# Description

|

|
||
|
|
This derivation uses a [yarn2nix](https://github.com/nix-community/yarn2nix) to generate a Nix store package containing all NodeJS dependencies.
|
||
|
|
|
||
|
|
# Details
|
||
|
|
|
||
|
|
If you look at [`nix/deps/nodejs/default.nix`](./default.nix) you'll see that it it loads `package.json` and `yarn.lock` files and uses them to generate the derivation:
|
||
|
|
```sh
|
||
|
|
> make nix-repl
|
||
|
|
Welcome to Nix version 2.3.9. Type :? for help.
|
||
|
|
|
||
|
|
nix-repl> pkgs.deps.nodejs
|
||
|
|
«derivation /nix/store/23mpmpjjnq7miclv6bc6ilgypy8wz69p-status-react-node-deps-1.8.0.drv»
|
||
|
|
```
|
||
|
|
You can build the derivation:
|
||
|
|
```
|
||
|
|
nix-repl> :b pkgs.deps.nodejs
|
||
|
|
|
||
|
|
this derivation produced the following outputs:
|
||
|
|
out -> /nix/store/dqb2cjyz1g6n7jic07058y26lnmgaaz9-status-react-node-deps-1.8.0
|
||
|
|
```
|
||
|
|
And look inside:
|
||
|
|
```
|
||
|
|
> cd /nix/store/dqb2cjyz1g6n7jic07058y26lnmgaaz9-status-react-node-deps-1.8.0
|
||
|
|
> ls
|
||
|
|
deps node_modules
|
||
|
|
> ls node_modules | grep react-native-image
|
||
|
|
react-native-image-crop-picker
|
||
|
|
react-native-image-resizer
|
||
|
|
react-native-image-viewing
|

# Known Issues
|
||
|
|
|
||
|
|
It's important that dependencies from GitHub are added in a correct format:
|
||
|
|
```
|
||
|
|
git+https://github.com/status-im/bignumber.js.git#v4.0.2-status
|
||
|
|
```
|
||
|
|
Notice three things:
|
||
|
|
|
||
|
|
* `git+` prefix for the `https://` URL
|
||
|
|
* Repository name ends with `.git`
|
||
|
|
* Tag or branch is added after `#` character
|
||
|
|
|
||
|
|
__WARNING__: Using branches can cause dependencies to change their hash and cause builds to fail. Using them during development is fine, but tags should be used in the final version.
|
||
|
|
|
||
|
|
If this format is not used correctly you can see issues like:
|
||
|
|
```
|
||
|
|
fatal: unable to access 'https://github.com/status-im/bignumber.js.git/': Could not resolve host: github.com
|
||
|
|
```
|
||
|
|
or
|
||
|
|
```
|
||
|
|
error Couldn't find any versions for "bignumber.js" that matches "github.com/status-im/bignumber.js.git#v4.0.2-status" in our cache (possible versions are ""). This is usually caused by a missing entry in the lockfile, running Yarn without the --offline flag may help fix this issue.
|
||
|
|
```
|
||
|
|
or
|
||
|
|
```
|
||
|
|
error Can't make a request in offline mode ("https://codeload.github.com/status-im/bignumber.js/tar.gz/f322b670969512a35c84441036a0ba4836a96428")
