Summary:
Our build system doesn’t make it easy to have two separate React
applications, which we would like to have for the V1 and V3 branches.
Instead, we’ll implement a bridge to maintain compatibility.
The plan looks like this:
1. Change the app from pointing to V1 to pointing to a bridge
2. Move the router into the bridge and move the V1 app from the `/`
route to the `/v1` route (e.g., `/v1/explorer`)
3. Add a V3 app under the `/v3` route
4. ???
5. Delete the V1 app and remove it from the bridge
6. Delete the bridge and move the V3 app from the `/v3` route to `/`
This commit implements Step 1.
Test Plan:
To verify that the bridge is in fact showing, apply
```diff
diff --git a/src/bridge/app/index.js b/src/bridge/app/index.js
index 379e289..72e784c 100644
--- a/src/bridge/app/index.js
+++ b/src/bridge/app/index.js
@@ -9,5 +9,11 @@ const root = document.getElementById("root");
if (root == null) {
throw new Error("Unable to find root element!");
}
-ReactDOM.render(<V1App />, root);
+ReactDOM.render(
+ <React.Fragment>
+ <h1>Hello</h1>
+ <V1App />
+ </React.Fragment>,
+ root
+);
registerServiceWorker();
```
and say “hello” back to the app.
