build: implement a monorepo with Lerna TL;DR ===== `yarn install` in a fresh clone of the repo. `yarn reboot` when switching branches. When pulling in these changes, there may be untracked files at the root in all/some of: ``` .embark/ .nyc_output/ coverage/ dist/ embark-ui/ test_apps/ ``` They can be safely deleted since those paths are no longer in use at the root. Many of the scripts in the top-level `package.json` support Lerna's [filter options]. For example: `yarn build --scope embark` build only `packages/embark`. `yarn build --ignore embark-ui` build everything except `packages/embark-ui`. Scoping scripts will be more useful when there are more packages in the monorepo and, for example, `yarn start` doesn't need to be invoked for all of them while working on just a few of them simultaneously, e.g `embark` and `embarkjs`. It's also possible to `cd` into a particular package and run its scripts directly: ``` cd packages/embark && yarn watch ``` Hot Topics & Questions ====================== What should be done about the [README][embark-readme] for `packages/embark`? Should the top-level README be duplicated in that package? Lerna is setup to use [Fixed/Locked mode][fixed-locked], and accordingly `packages/embark-ui` is set to `4.0.0-beta.0`. The same will be true when adding embarkjs, swarm-api, etc. to the monorepo. Is this acceptable or do we want to use [Independent mode][independent]? Scripts ======= If a package doesn't have a matching script, `lerna run` skips it automatically. For example, `packages/embark-ui` doesn't have a `typecheck` script. `yarn build` ------------ Runs babel, webpack, etc. according to a package's `build` script. `yarn build:no-ui` is a shortcut for `yarn build --ignore embark-ui`. `yarn ci` --------- Runs a series of scripts relevant in a CI context according to a package's `ci` script. For `packages/embark` that's `lint typecheck build test package`. Also runs the `ci` script of the embedded `test_dapps` monorepo. `yarn clean` ------------ Runs rimraf, etc. according to a package's `clean` script. `yarn globalize` ---------------- Makes the development embark available on the global PATH, either via symlink (Linux, macOS) or a shim script (Windows). `yarn lint` ----------- Runs eslint, etc. according to a package's `lint` script. `yarn package` -------------- Invokes `npm pack` according to a package's `package` script. `yarn qa` --------- Very similar to `ci`, runs a series of scripts according to a package's `qa` script. The big difference between `ci` and `qa` is that at the top-level `qa` first kicks off `reboot:full`. There is a `preqa` script ([invoked automatically][npm-scripts]), which is a bit of a wart. It makes sure that `embark reset` can be run successfully in `packages/embark/templates/` when the `reboot` script invokes the `reset` script. The `qa` script is invoked by `yarn release` before the latter proceeds to invoke `lerna publish`. `yarn reboot` ------------- Invokes the `reset` script and then does `yarn install`. The `reboot:full` variant invokes `reset:full` and then does `yarn install`. `yarn release` -------------- Works in concert with [lerna publish], which will prompt to verify the version before proceeding. Use `n` to cancel instead of `ctrl-c` as `lerna publish` has been seen to occasionally misbehave when not exited cleanly (e.g. creating a tag when it shouldn't have). ``` yarn release [bump] [--options] ``` `[bump]` see [`publish` positionals][pub-pos] and [`version` positionals][ver-pos]; an exact version can also be specified. * `--preid` prerelease identifier, e.g. `beta`; when doing a prerelease bump will default to whatever identifier is currently in use. * `--dist-tag` registry distribution tag, defaults to `latest`. * `--message` commit message format, defaults to `chore(release): %v`. * `--sign` indicates that the git commit and tag should be signed; not signed by default. * `--release-branch` default is `master`; must match the current branch. * `--git-remote` default is `origin`. * `--registry` default is `https://registry.npmjs.org/` per the top-level [`lerna.json`][lerna-json]. To release `4.0.0-beta.1` as `embark@next` (assuming version is currently at `4.0.0-beta.0`) could do: ``` yarn release prerelease --dist-tag next ``` For test releases (there is no longer a `--dry-run` option) [verdaccio] and a filesystem git remote can be used. Condensend instructions: ``` mkdir -p ~/temp/clones && cd ~/temp/clones git clone git@github.com:embark-framework/embark.git cd ~/repos/embark git remote add FAKEembark ~/temp/clones/embark ``` in another terminal: ``` npm i -g verdaccio && verdaccio ``` in the first terminal: ``` yarn release --git-remote FAKEembark --registry http://localhost:4873/ ``` `yarn reset` ------------ Invokes cleaning and resetting steps according to a package's `reset` script. The big difference between `clean` and `reset` is that `reset` is intended to delete a package's `node_modules`. The `reset:full` variant deletes the monorepo's top-level `node_modules` at the end. That shouldn't be necessary too often, e.g. in day-to-day work when switching branches, which is why there is `reboot` / `reset` vs. `reboot:full` / `reset:full`. Errors may be seen related to invocation of `embark reset` if embark is not built, but `reset` will still complete successfully. `yarn start` ------------ Runs babel, webpack, tsc, etc. (in parallel, in watch mode) according to a package's `start` script. `yarn test` ----------- Run mocha, etc. according to a package's `test` script. The `test:full` variant runs a series of scripts: `lint typecheck test test_dapps`. `yarn test_dapps` ----------------- Runs the `test` script of the embedded `test_dapps` monorepo. The `test_dapps:ci` and `test_dapps:qa` variants run the `ci` and `qa` scripts of the embedded `test_dapps` monorepo, respectively. `yarn typecheck` ---------------- Runs tsc, etc. according to a package's `typecheck` script. Notes ===== `npx` is used in some of the top-level and package scripts to ensure the scripts can run even if `node_modules` is missing. [`"nohoist"`][nohoist] specifies a couple of embark packages because [`restrictPath`][restrictpath] is interfering with access to modules that are located in a higher-up `node_modules`. All dependencies in `packages/embark-ui` have been made `devDependencies` since its production build is self-contained. `packages/embark`'s existing CHANGELOG's formatting has been slightly adjusted to match the formatting that Lerna will use going forward (entries in the log haven't been modified). Lerna will generate a CHANGELOG at the top-level and in each package. Since we're transitioning to a monorepo, things may look a little wonky with respect to old entries in `packages/embark/CHANGELOG.md` and going forward we need to consider how scoping our commits corresponds to member-packages of the monorepo. In `packages/embark`, `test` invokes `scripts/test`, which starts a child process wherein `process.env.DAPP_PATH` is a temporary path that has all of `packages/embark/dist/test` copied into it, so that paths to test helpers/fixtures don't need to be prefixed with `dist/test/` and so that a `.embark` directory doesn't get written into `packages/embark`. The `"engines"` specified in top-level and packages' `package.json` reflect a node and npm pair that match (a source of confusion in the past). The pair was chosen according to the first post v5 npm that's bundled with node. A `"runtime"` key/object has been introduced in `packages/embark/package.json` which is used as the basis for specifying the minimum version of node that can be used to run embark, and that's what is checked by `bin/embark`. Some changes have been introduced, e.g. in `lib/core/config` and `lib/utils/solidity/remapImports` so that it's not implicitly assumed that `process.env.DAPP_PATH` / `fs.dappPath()` are the same as `process.cwd()`. There are probably several++ places where that assumption is still in effect, and we should work to identify and correct them. `embark reset` now deletes `embarkArtifacts/` within a dapp root, and `embarkArtifacts/` is git-ignored. `lib/core/env` adds all `node_modules` relative to `process.env.EMBARK_PATH` to `NODE_PATH` so that embark's modules can be resolved as expected whether embark's `node_modules` have been deduped or are installed in npm's flat "global style". `checkDependencies` has been inlined (see `lib/utils/checkDependencies`) and slightly modified to support dependencies that have been hoisted into a higher-up `node_modules`, e.g. as part of a yarn workspace. eslint has been disabled for that script to avoid more involved changes to it. `test_apps` is not in `packages/embark`; rather, there is `test_dapps` at the top-level of the monorepo. `test_dapps` is an embedded monorepo, and its `ci` / `qa` scripts `npm install` embark from freshly built tarballs of the packages in the outer monorepo and then use that installation to run `embark test` in the dapps. This should allow us to rapidly detect breakage related to auto-bumps in transitive dependencies.

build: implement collective typecheck This PR replaces #2057. Implement a collective typecheck action that can be invoked in the root of the monorepo with `yarn typecheck` or in watch-mode with `yarn watch:typecheck`. Include the watch-mode typecheck action as part of `yarn start` (a.k.a `yarn watch`). To activate collective typecheck for a package in the monorepo, its `package.json` file should specify: ``` { "embark-collective": { "typecheck": true } } ``` -or- ``` { "embark-collective": { "typecheck": {...} } } ``` Where `{...}` above is a `tsconfig.json` fragment that will be merged into the config generated for the package according the same rules that `tsc` applies when merging [configs][config]. When collective typecheck begins, it generates a `tsconfig.json` for the root of the monorepo and for each package that is activated for the action. If the generated JSON is different than what's on disk for the respective root/package config, or if the config is not present on disk, then it will be written. Changes to generated `tsconfig.json` files should be committed; such changes will arise when there are structural changes to the monorepo, e.g. a package is added, removed, moved and/or the directory containing it is renamed. Since the configs are only generated at the beginning of collective typecheck, when structural changes are made in the monorepo `yarn typecheck` (or `yarn start` or `yarn watch:typecheck`) should be restarted. Nearly all of the packages in the monorepo (i.e. all those for which it makes sense) have been activated for collective typecheck. Even those packages that don't contain `.ts` sources are activated because `tsc` can make better sense of the code base as a whole owing to the project references included in the generated `tsconfig.json` files. Also, owing to the fully cross-referenced `tsconfig.json` files, it's possible for `tsc` to type check the whole code base without babel (`yarn build` or `yarn watch:build`) having been run beforehand. NOTE that a "cold typecheck" of the whole monorepo is resource intensive: on this author's 2019 MacBook Pro it takes around three minutes, the fans spin up, and `tsc` uses nearly 0.5 GB of RAM. However, once a full typecheck has completed, the next full typecheck will complete in a few seconds or less; and when running in watch-mode there is likewise a big speedup once a full typecheck has completed, whether that full check happened before it's running in watch-mode or when watch-mode itself resulted in a full check before switching automatically to incremental check, as well a corresponding big reduction in resource consumption. A full check will be needed any time `yarn typecheck` (or `yarn start` or `yarn watch:typecheck`) is run in a fresh clone plus `yarn install`, or after doing `yarn reboot[:full]` or `yarn reset`. The combination of options in each generated package-level `tsconfig.json` and the root `tsconfig.base.json` result in `tsc` writing `.d.ts` files (TypeScript declaration files) into the `dist/` directory of each package. That output is intended to live side-by-side with babel's output, and therefore the `"rootDir"` option in each generated config is set to `"./src"`. In projects activated for collective typecheck, `.js` may be converted to `.ts` and/or `.ts` sources may be added without any additional changes needed in package-level `package.json`. --- Reorganize types in `packages/core/typings` (a.k.a `@types/embark`) into `packages/core/core` (`embark-core`), refactor other packages' imports accordingly, and delete `packages/core/typings` from the monorepo. This results in some similarly named but incompatible types exported from `embark-core` (e.g. `Events` and `EmbarkEvents`, the latter being the one from `packages/core/typings`); future refactoring should consolidate those types. To avoid circular dependency relationships it's also necessary to split out `Engine` from `embark-core` into its own package (`embark-engine`) and to introduce a bit of duplication, e.g. the `Maybe` type that's now defined in both `embark-i18n` and `embark-core`. In the process of the types reorg, move many dependencies spec'd in various `package.json` to the `package.json` of the package/s that actually depend on them, e.g. many are moved from `packages/embark/package.json` to `packages/core/engine/package.json`. Related to those moves, fix some Node.js `require`-logic related to bug-prone dependency resolution. Fix all type errors that appeared as a result of activating collective typecheck across the whole monorepo. Reactivate `tslint` in `packages/core/core` and fix the remaining linter errors. Tidy up and add a few items in the root `package.json` scripts. Bump lerna from `3.16.4` to `3.19.0`. Bumpt typescript from `3.6.3` to `3.7.2`. Bumpt tslint from `5.16.0` to `5.20.1`. Make various changes related to packages' `import`/`require`ing packages that weren't spec'd in their respective `package.json`. More refactoring is needed in this regard, but changes were made as the problems were observed in the process of authoring this PR.

It makes sure that `embark reset` can be run successfully in `packages/embark/templates/` when the `reboot` script invokes the `reset` script. The `qa` script is invoked by `yarn release` before the latter proceeds to invoke `lerna publish`. `yarn reboot` ------------- Invokes the `reset` script and then does `yarn install`. The `reboot:full` variant invokes `reset:full` and then does `yarn install`. `yarn release` -------------- Works in concert with [lerna publish], which will prompt to verify the version before proceeding. Use `n` to cancel instead of `ctrl-c` as `lerna publish` has been seen to occasionally misbehave when not exited cleanly (e.g. creating a tag when it shouldn't have). ``` yarn release [bump] [--options] ``` `[bump]` see [`publish` positionals][pub-pos] and [`version` positionals][ver-pos]; an exact version can also be specified. * `--preid` prerelease identifier, e.g. `beta`; when doing a prerelease bump will default to whatever identifier is currently in use. * `--dist-tag` registry distribution tag, defaults to `latest`. * `--message` commit message format, defaults to `chore(release): %v`. * `--sign` indicates that the git commit and tag should be signed; not signed by default. * `--release-branch` default is `master`; must match the current branch. * `--git-remote` default is `origin`. * `--registry` default is `https://registry.npmjs.org/` per the top-level [`lerna.json`][lerna-json]. To release `4.0.0-beta.1` as `embark@next` (assuming version is currently at `4.0.0-beta.0`) could do: ``` yarn release prerelease --dist-tag next ``` For test releases (there is no longer a `--dry-run` option) [verdaccio] and a filesystem git remote can be used. Condensend instructions: ``` mkdir -p ~/temp/clones && cd ~/temp/clones git clone git@github.com:embark-framework/embark.git cd ~/repos/embark git remote add FAKEembark ~/temp/clones/embark ``` in another terminal: ``` npm i -g verdaccio && verdaccio ``` in the first terminal: ``` yarn release --git-remote FAKEembark --registry http://localhost:4873/ ``` `yarn reset` ------------ Invokes cleaning and resetting steps according to a package's `reset` script. The big difference between `clean` and `reset` is that `reset` is intended to delete a package's `node_modules`. The `reset:full` variant deletes the monorepo's top-level `node_modules` at the end. That shouldn't be necessary too often, e.g. in day-to-day work when switching branches, which is why there is `reboot` / `reset` vs. `reboot:full` / `reset:full`. Errors may be seen related to invocation of `embark reset` if embark is not built, but `reset` will still complete successfully. `yarn start` ------------ Runs babel, webpack, tsc, etc. (in parallel, in watch mode) according to a package's `start` script. `yarn test` ----------- Run mocha, etc. according to a package's `test` script. The `test:full` variant runs a series of scripts: `lint typecheck test test_dapps`. `yarn test_dapps` ----------------- Runs the `test` script of the embedded `test_dapps` monorepo. The `test_dapps:ci` and `test_dapps:qa` variants run the `ci` and `qa` scripts of the embedded `test_dapps` monorepo, respectively. `yarn typecheck` ---------------- Runs tsc, etc. according to a package's `typecheck` script. Notes ===== `npx` is used in some of the top-level and package scripts to ensure the scripts can run even if `node_modules` is missing. [`"nohoist"`][nohoist] specifies a couple of embark packages because [`restrictPath`][restrictpath] is interfering with access to modules that are located in a higher-up `node_modules`. All dependencies in `packages/embark-ui` have been made `devDependencies` since its production build is self-contained. `packages/embark`'s existing CHANGELOG's formatting has been slightly adjusted to match the formatting that Lerna will use going forward (entries in the log haven't been modified). Lerna will generate a CHANGELOG at the top-level and in each package. Since we're transitioning to a monorepo, things may look a little wonky with respect to old entries in `packages/embark/CHANGELOG.md` and going forward we need to consider how scoping our commits corresponds to member-packages of the monorepo. In `packages/embark`, `test` invokes `scripts/test`, which starts a child process wherein `process.env.DAPP_PATH` is a temporary path that has all of `packages/embark/dist/test` copied into it, so that paths to test helpers/fixtures don't need to be prefixed with `dist/test/` and so that a `.embark` directory doesn't get written into `packages/embark`. The `"engines"` specified in top-level and packages' `package.json` reflect a node and npm pair that match (a source of confusion in the past). The pair was chosen according to the first post v5 npm that's bundled with node. A `"runtime"` key/object has been introduced in `packages/embark/package.json` which is used as the basis for specifying the minimum version of node that can be used to run embark, and that's what is checked by `bin/embark`. Some changes have been introduced, e.g. in `lib/core/config` and `lib/utils/solidity/remapImports` so that it's not implicitly assumed that `process.env.DAPP_PATH` / `fs.dappPath()` are the same as `process.cwd()`. There are probably several++ places where that assumption is still in effect, and we should work to identify and correct them. `embark reset` now deletes `embarkArtifacts/` within a dapp root, and `embarkArtifacts/` is git-ignored. `lib/core/env` adds all `node_modules` relative to `process.env.EMBARK_PATH` to `NODE_PATH` so that embark's modules can be resolved as expected whether embark's `node_modules` have been deduped or are installed in npm's flat "global style". `checkDependencies` has been inlined (see `lib/utils/checkDependencies`) and slightly modified to support dependencies that have been hoisted into a higher-up `node_modules`, e.g. as part of a yarn workspace. eslint has been disabled for that script to avoid more involved changes to it. `test_apps` is not in `packages/embark`; rather, there is `test_dapps` at the top-level of the monorepo. `test_dapps` is an embedded monorepo, and its `ci` / `qa` scripts `npm install` embark from freshly built tarballs of the packages in the outer monorepo and then use that installation to run `embark test` in the dapps. This should allow us to rapidly detect breakage related to auto-bumps in transitive dependencies.

build: implement collective typecheck This PR replaces #2057. Implement a collective typecheck action that can be invoked in the root of the monorepo with `yarn typecheck` or in watch-mode with `yarn watch:typecheck`. Include the watch-mode typecheck action as part of `yarn start` (a.k.a `yarn watch`). To activate collective typecheck for a package in the monorepo, its `package.json` file should specify: ``` { "embark-collective": { "typecheck": true } } ``` -or- ``` { "embark-collective": { "typecheck": {...} } } ``` Where `{...}` above is a `tsconfig.json` fragment that will be merged into the config generated for the package according the same rules that `tsc` applies when merging [configs][config]. When collective typecheck begins, it generates a `tsconfig.json` for the root of the monorepo and for each package that is activated for the action. If the generated JSON is different than what's on disk for the respective root/package config, or if the config is not present on disk, then it will be written. Changes to generated `tsconfig.json` files should be committed; such changes will arise when there are structural changes to the monorepo, e.g. a package is added, removed, moved and/or the directory containing it is renamed. Since the configs are only generated at the beginning of collective typecheck, when structural changes are made in the monorepo `yarn typecheck` (or `yarn start` or `yarn watch:typecheck`) should be restarted. Nearly all of the packages in the monorepo (i.e. all those for which it makes sense) have been activated for collective typecheck. Even those packages that don't contain `.ts` sources are activated because `tsc` can make better sense of the code base as a whole owing to the project references included in the generated `tsconfig.json` files. Also, owing to the fully cross-referenced `tsconfig.json` files, it's possible for `tsc` to type check the whole code base without babel (`yarn build` or `yarn watch:build`) having been run beforehand. NOTE that a "cold typecheck" of the whole monorepo is resource intensive: on this author's 2019 MacBook Pro it takes around three minutes, the fans spin up, and `tsc` uses nearly 0.5 GB of RAM. However, once a full typecheck has completed, the next full typecheck will complete in a few seconds or less; and when running in watch-mode there is likewise a big speedup once a full typecheck has completed, whether that full check happened before it's running in watch-mode or when watch-mode itself resulted in a full check before switching automatically to incremental check, as well a corresponding big reduction in resource consumption. A full check will be needed any time `yarn typecheck` (or `yarn start` or `yarn watch:typecheck`) is run in a fresh clone plus `yarn install`, or after doing `yarn reboot[:full]` or `yarn reset`. The combination of options in each generated package-level `tsconfig.json` and the root `tsconfig.base.json` result in `tsc` writing `.d.ts` files (TypeScript declaration files) into the `dist/` directory of each package. That output is intended to live side-by-side with babel's output, and therefore the `"rootDir"` option in each generated config is set to `"./src"`. In projects activated for collective typecheck, `.js` may be converted to `.ts` and/or `.ts` sources may be added without any additional changes needed in package-level `package.json`. --- Reorganize types in `packages/core/typings` (a.k.a `@types/embark`) into `packages/core/core` (`embark-core`), refactor other packages' imports accordingly, and delete `packages/core/typings` from the monorepo. This results in some similarly named but incompatible types exported from `embark-core` (e.g. `Events` and `EmbarkEvents`, the latter being the one from `packages/core/typings`); future refactoring should consolidate those types. To avoid circular dependency relationships it's also necessary to split out `Engine` from `embark-core` into its own package (`embark-engine`) and to introduce a bit of duplication, e.g. the `Maybe` type that's now defined in both `embark-i18n` and `embark-core`. In the process of the types reorg, move many dependencies spec'd in various `package.json` to the `package.json` of the package/s that actually depend on them, e.g. many are moved from `packages/embark/package.json` to `packages/core/engine/package.json`. Related to those moves, fix some Node.js `require`-logic related to bug-prone dependency resolution. Fix all type errors that appeared as a result of activating collective typecheck across the whole monorepo. Reactivate `tslint` in `packages/core/core` and fix the remaining linter errors. Tidy up and add a few items in the root `package.json` scripts. Bump lerna from `3.16.4` to `3.19.0`. Bumpt typescript from `3.6.3` to `3.7.2`. Bumpt tslint from `5.16.0` to `5.20.1`. Make various changes related to packages' `import`/`require`ing packages that weren't spec'd in their respective `package.json`. More refactoring is needed in this regard, but changes were made as the problems were observed in the process of authoring this PR.

build: implement a monorepo with Lerna TL;DR ===== `yarn install` in a fresh clone of the repo. `yarn reboot` when switching branches. When pulling in these changes, there may be untracked files at the root in all/some of: ``` .embark/ .nyc_output/ coverage/ dist/ embark-ui/ test_apps/ ``` They can be safely deleted since those paths are no longer in use at the root. Many of the scripts in the top-level `package.json` support Lerna's [filter options]. For example: `yarn build --scope embark` build only `packages/embark`. `yarn build --ignore embark-ui` build everything except `packages/embark-ui`. Scoping scripts will be more useful when there are more packages in the monorepo and, for example, `yarn start` doesn't need to be invoked for all of them while working on just a few of them simultaneously, e.g `embark` and `embarkjs`. It's also possible to `cd` into a particular package and run its scripts directly: ``` cd packages/embark && yarn watch ``` Hot Topics & Questions ====================== What should be done about the [README][embark-readme] for `packages/embark`? Should the top-level README be duplicated in that package? Lerna is setup to use [Fixed/Locked mode][fixed-locked], and accordingly `packages/embark-ui` is set to `4.0.0-beta.0`. The same will be true when adding embarkjs, swarm-api, etc. to the monorepo. Is this acceptable or do we want to use [Independent mode][independent]? Scripts ======= If a package doesn't have a matching script, `lerna run` skips it automatically. For example, `packages/embark-ui` doesn't have a `typecheck` script. `yarn build` ------------ Runs babel, webpack, etc. according to a package's `build` script. `yarn build:no-ui` is a shortcut for `yarn build --ignore embark-ui`. `yarn ci` --------- Runs a series of scripts relevant in a CI context according to a package's `ci` script. For `packages/embark` that's `lint typecheck build test package`. Also runs the `ci` script of the embedded `test_dapps` monorepo. `yarn clean` ------------ Runs rimraf, etc. according to a package's `clean` script. `yarn globalize` ---------------- Makes the development embark available on the global PATH, either via symlink (Linux, macOS) or a shim script (Windows). `yarn lint` ----------- Runs eslint, etc. according to a package's `lint` script. `yarn package` -------------- Invokes `npm pack` according to a package's `package` script. `yarn qa` --------- Very similar to `ci`, runs a series of scripts according to a package's `qa` script. The big difference between `ci` and `qa` is that at the top-level `qa` first kicks off `reboot:full`. There is a `preqa` script ([invoked automatically][npm-scripts]), which is a bit of a wart. It makes sure that `embark reset` can be run successfully in `packages/embark/templates/` when the `reboot` script invokes the `reset` script. The `qa` script is invoked by `yarn release` before the latter proceeds to invoke `lerna publish`. `yarn reboot` ------------- Invokes the `reset` script and then does `yarn install`. The `reboot:full` variant invokes `reset:full` and then does `yarn install`. `yarn release` -------------- Works in concert with [lerna publish], which will prompt to verify the version before proceeding.
