+# PoC for multi-gitter
+
+PoC for using [multi-gitter](https://github.com/lindell/multi-gitter) to do bulk upgrade over multiple repos
+
+## Steps
+1. install multi-gitter as [described in the repo](https://github.com/lindell/multi-gitter?tab=readme-ov-file#install) 
+1. update the `config.yml` as you see fit (i.e. to include certain repos)
+1. run `multi-gitter run "node $PWD/script.js" --config ./config.yml`

+/**
+ * script to be run on all repos to upgrade to the latest version of app-platform tools
+ * which uses Vite and upgrades to React 18.
+ *
+ * It does few things to make the process easier:
+ * 1. Upgrade to the latest version of cli-app-scripts, cli-style and UI library
+ * 2. Removes the resolutions for these packages from package.json
+ * 3. Runs d2 migrate script, which mainly updates d2.config and js extensions to use jsx (which is needed to optimise Vite performance)
+ * 4. Dedupes the dependencies with npx yarn-deduplicate
+ * 5. Upgrades test dependencies (@testing-library et al.) to a version compatible with React@18
+ * 6. Run `yarn format`
+ * 7. Check that React is definitely version 18
+ * 8. Adds a React-18 badge to the README
+ * To run it, do: multi-gitter run "node $PWD/script.js" --config ./config.yml
