- Upgrades eslint from v8 to v9
- Upgrades all other eslint packages. We will have to do a new
full-project lint, as new rules have been added
- Upgrades husky from v8 to v9
- Upgrades lint-staged from v14 to v15
- Moves the old .eslintrc.cjs file format to the new eslint.config.js
flat file format.
Previously, we were very specific regarding which rules are applied to
which files. Now that `extends` is no longer a thing, I have to use
deepMerge & imports instead.
This is rather uncommon and is not a documented pattern - e.g.
typescript-eslint docs want us to add the default typescript-eslint
rules to the top-level & then disable it in files using the
disable-typechecked config.
However, I hate this opt-out approach. The way I did it here adds a lot
of clarity as to which rules are applied to which files, and is pretty
easy to read. Much less black magic
## .eslintignore
These files are no longer supported (see
https://eslint.org/docs/latest/use/configure/migration-guide#ignoring-files).
I moved the entries to the ignores property in the eslint config. => one
less file in each package folder!
**BREAKING:**
- bumps minimum required next.js version from `14.3.0-canary.68` to
`15.0.0-rc.0`
- bumps minimum required react and react-dom versions to `19.0.0
`(`19.0.0-rc-f994737d14-20240522` should be used)
- `@types/react` and `@types/react-dom` have to be bumped to
`npm:types-react@19.0.0-beta.2` using overrides and pnpm overrides, if
you want correct types. You can find an example of this here:
https://github.com/payloadcms/payload/pull/6429/files#diff-10cb9e57a77733f174ee2888587281e94c31f79e434aa3f932a8ec72fa7a5121L32
## Issues
- Bunch of todos for our react-select package which is having type
issues. Works fine, just type issues. Their type defs are importing JSX
in a weird way, we likely just have to wait until they fix them in a
future update.
