I think it's easier to review this PR commit by commit, so I'll explain
it this way:
## Commits
1. [parallelize eslint script (still showing logs results in
serial)](c9ac49c12d):
Previously, `--concurrency 1` was added to the script to make the logs
more readable. However, turborepo has an option specifically for these
use cases: `--log-order=grouped` runs the tasks in parallel but outputs
them serially. As a result, the lint script is now significantly faster.
2. [run pnpm
lint:fix](9c128c276a)
The auto-fix was run, which resolved some eslint errors that were
slipped in due to the use of `no-verify`. Most of these were
`perfectionist` fixes (property ordering) and the removal of unnecessary
assertions. Starting with this PR, this won't happen again in the
future, as we'll be verifying the linter in every PR across the entire
codebase (see commit 7).
3. [fix eslint non-autofixable
errors](700f412a33)
All manual errors have been resolved except for the configuration errors
addressed in commit 5. Most were React compiler violations, which have
been disabled and commented out "TODO" for now. There's also an unused
`use no memo` and a couple of `require` errors.
4. [move react-compiler linter to eslint-config
package](4f7cb4d63a)
To simplify the eslint configuration. My concern was that there would be
a performance regression when used in non-react related packages, but
none was experienced. This is probably because it only runs on .tsx
files.
5. [remove redundant eslint config files and fix
allowDefaultProject](a94347995a)
The main feature introduced by `typescript-eslint` v8 was
`projectService`, which automatically searches each file for the closest
`tsconfig`, greatly simplifying configuration in monorepos
([source](https://typescript-eslint.io/blog/announcing-typescript-eslint-v8#project-service)).
Once I moved `projectService` to `packages/eslint-config`, all the other
configuration files could be easily removed.
I confirmed that pnpm lint still works on individual packages.
The other important change was that the pending eslint errors from
commits 2 and 3 were resolved. That is, some files were giving the
error: "[File] was not found by the project service. Consider either
including it in the tsconfig.json or including it in
allowDefaultProject." Below I copy the explanatory comment I left in the
code:
```ts
// This is necessary because `tsconfig.base.json` defines `"rootDir": "${configDir}/src"`,
// And the following files aren't in src because they aren't transpiled.
// This is typescript-eslint's way of adding files that aren't included in tsconfig.
// See: https://typescript-eslint.io/troubleshooting/typed-linting/#i-get-errors-telling-me--was-not-found-by-the-project-service-consider-either-including-it-in-the-tsconfigjson-or-including-it-in-allowdefaultproject
// The best practice is to have a tsconfig.json that covers ALL files and is used for
// typechecking (with noEmit), and a `tsconfig.build.json` that is used for the build
// (or alternatively, swc, tsup or tsdown). That's what we should ideally do, in which case
// this hardcoded list wouldn't be necessary. Note that these files don't currently go
// through ts, only through eslint.
```
6. [Differentiate errors from warnings in VScode ESLint
Rules](5914d2f48d)
There's no reason to do that. If an eslint rule isn't an error, it
should be disabled or converted to a warning.
7. [Disable skip lint, and lint over the entire repo now that it's
faster](e4b28f1360)
The GitHub action linted only the files that had changed in the PR.
While this seems like a good idea, once exceptions were introduced with
[skip lint], they opened the door to propagating more and more errors.
Often, the linter was skipped, not because someone introduced new
errors, but because they were trying to avoid those that had already
crept in, sometimes accidentally introducing new ones.
On the other hand, `pnpm lint` now runs in parallel (commit 1), so it's
not that slow. Additionally, it runs in parallel with other GitHub
actions like e2e tests, which take much longer, so it can't represent a
bottleneck in CI.
8. [fix lint in next
package](4506595f91)
Small fix missing from commit 5
9. [Merge remote-tracking branch 'origin/main' into
fix-eslint](563d4909c1)
10. [add again eslint.config.js in payload
package](78f6ffcae7)
The comment in the code explains it. Basically, after the merge from
main, the payload package runs out of memory when linting, probably
because it grew in recent PRs. That package will sooner or later
collapse for our tooling, so we may have to split it. It's already too
big.
## Future Actions
- Resolve React compiler violations, as mentioned in commit 3.
- Decouple the `tsconfig` used for typechecking and build across the
entire monorepo (as explained in point 5) to ensure ts coverage even for
files that aren't transpiled (such as scripts).
- Remove the few remaining `eslint.config.js`. I had to leave the
`richtext-lexical` and `next` ones for now. They could be moved to the
root config and scoped to their packages, as we do for example with
`templates/vercel-postgres/**`. However, I couldn't get it to work, I
don't know why.
- Make eslint in the test folder usable. Not only are we not linting
`test` in CI, but now the `pnpm eslint .` command is so large that my
computer freezes. If each suite were its own package, this would be
solved, and dynamic codegen + git hooks to modify tsconfig.base.json
wouldn't be necessary
([related](https://github.com/payloadcms/payload/pull/11984)).
The `localized` properly was not stripped out of referenced block fields, if any parent was localized. For normal fields, this is done in sanitizeConfig. As the same referenced block config can be used in both a localized and non-localized config, we are not able to strip it out inside sanitizeConfig by modifying the block config.
Instead, this PR had to bring back tedious logic to handle it everywhere the `field.localized` property is accessed. For backwards-compatibility, we need to keep the existing sanitizeConfig logic. In 4.0, we should remove it to benefit from better test coverage of runtime field.localized handling - for now, this is done for our test suite using the `PAYLOAD_DO_NOT_SANITIZE_LOCALIZED_PROPERTY` flag.
This will hopefully allow pnpm to reliably install the correct lexical version, as lexical is now solely part of our `dependencies`. Currently, pnpm completely disregards lexical version bumps until the user deletes both the lockfile and their `node_modules` folder.
The downside of this is that pnpm will no longer throw a warning if payload is installed in a project with a mismatching lexical version. However, noone read that warning anyways, and our runtime dependency checker is more reliable.
This PR fixes 2 eslint config issues that prevented it from running in our test dir
- spec files were ignored by the root eslint config. This should have only ignored spec files within our packages, as they are ignored by the respective package tsconfigs
- defining the payload plugin crashed eslint in our test dir, as it was already defined in the root eslint config it was inheriting
Having the `scripts` dir re-use all packages from the top-level was
getting quite unwieldy. Created new `tools` directory that is part of
the workspace. Packages are exported with the `@tools` package
namespace.
Bumps Next.js to the latest version `15.1.3`. This affects only internal
`package.json` files (in the root dir and test)
Fixes errors from here https://github.com/payloadcms/payload/pull/10209
Previously, the following MDX could not be parsed by lexical:
```tsx
<RestExamples
data={[
{
operation: "Find"
}
]}
```
Instead, it had to be converted into valid JSON:
```tsx
<RestExamples
data={[
{
"operation": "Find"
}
]}
```
This PR permits using the first example, as it swaps out JSON.parse with
them ore lenient [json5](https://www.npmjs.com/package/json5) package
parser
Supports bi-directional import/export between MDX <=> Lexical. JSX will
be mapped to lexical blocks back and forth.
This will allow editing our mdx docs in payload while keeping mdx as the
source of truth

Payload uses `pino` for a logger. When using the error logger
`payload.logger.error` it is possible to pass any number of arguments
like this: `payload.logger.error('Some error ocurred', err)`. However,
in this scenario, the full error will not be serialized by `pino`. It
must be passed as the `err` property inside of an object in order to be
properly serialized.
This rule ensures that a user is using this function call to properly serialize the error.
Now enforcing curly brackets on all if statements. Includes auto-fixer.
```ts
// ❌ Bad
if (foo) foo++;
// ✅ Good
if (foo) {
foo++;
}
```
Note: this did not lint the `drizzle` package or any `db-*` packages.
This will be done in the future.
This PR makes three major changes to the codebase:
1. [Component Paths](#component-paths)
Instead of importing custom components into your config directly, they
are now defined as file paths and rendered only when needed. That way
the Payload config will be significantly more lightweight, and ensures
that the Payload config is 100% server-only and Node-safe. Related
discussion: https://github.com/payloadcms/payload/discussions/6938
2. [Client Config](#client-config)
Deprecates the component map by merging its logic into the client
config. The main goal of this change is for performance and
simplification. There was no need to deeply iterate over the Payload
config twice, once for the component map, and another for the client
config. Instead, we can do everything in the client config one time.
This has also dramatically simplified the client side prop drilling
through the UI library. Now, all components can share the same client
config which matches the exact shape of their Payload config (with the
exception of non-serializable props and mapped custom components).
3. [Custom client component are no longer
server-rendered](#custom-client-components-are-no-longer-server-rendered)
Previously, custom components would be server-rendered, no matter if
they are server or client components. Now, only server components are
rendered on the server. Client components are automatically detected,
and simply get passed through as `MappedComponent` to be rendered fully
client-side.
## Component Paths
Instead of importing custom components into your config directly, they
are now defined as file paths and rendered only when needed. That way
the Payload config will be significantly more lightweight, and ensures
that the Payload config is 100% server-only and Node-safe. Related
discussion: https://github.com/payloadcms/payload/discussions/6938
In order to reference any custom components in the Payload config, you
now have to specify a string path to the component instead of importing
it.
Old:
```ts
import { MyComponent2} from './MyComponent2.js'
admin: {
components: {
Label: MyComponent2
},
},
```
New:
```ts
admin: {
components: {
Label: '/collections/Posts/MyComponent2.js#MyComponent2', // <= has to be a relative path based on a baseDir configured in the Payload config - NOT relative based on the importing file
},
},
```
### Local API within Next.js routes
Previously, if you used the Payload Local API within Next.js pages, all
the client-side modules are being added to the bundle for that specific
page, even if you only need server-side functionality.
This `/test` route, which uses the Payload local API, was previously 460
kb. It is now down to 91 kb and does not bundle the Payload client-side
admin panel anymore.
All tests done
[here](https://github.com/payloadcms/payload-3.0-demo/tree/feat/path-test)
with beta.67/PR, db-mongodb and default richtext-lexical:
**dev /admin before:**

**dev /admin after:**

---
**dev /test before:**

**dev /test after:**

---
**build before:**

**build after::**

### Usage of the Payload Local API / config outside of Next.js
This will make it a lot easier to use the Payload config / local API in
other, server-side contexts. Previously, you might encounter errors due
to client files (like .scss files) not being allowed to be imported.
## Client Config
Deprecates the component map by merging its logic into the client
config. The main goal of this change is for performance and
simplification. There was no need to deeply iterate over the Payload
config twice, once for the component map, and another for the client
config. Instead, we can do everything in the client config one time.
This has also dramatically simplified the client side prop drilling
through the UI library. Now, all components can share the same client
config which matches the exact shape of their Payload config (with the
exception of non-serializable props and mapped custom components).
This is breaking change. The `useComponentMap` hook no longer exists,
and most component props have changed (for the better):
```ts
const { componentMap } = useComponentMap() // old
const { config } = useConfig() // new
```
The `useConfig` hook has also changed in shape, `config` is now a
property _within_ the context obj:
```ts
const config = useConfig() // old
const { config } = useConfig() // new
```
## Custom Client Components are no longer server rendered
Previously, custom components would be server-rendered, no matter if
they are server or client components. Now, only server components are
rendered on the server. Client components are automatically detected,
and simply get passed through as `MappedComponent` to be rendered fully
client-side.
The benefit of this change:
Custom client components can now receive props. Previously, the only way
for them to receive dynamic props from a parent client component was to
use hooks, e.g. `useFieldProps()`. Now, we do have the option of passing
in props to the custom components directly, if they are client
components. This will be simpler than having to look for the correct
hook.
This makes rendering them on the client a little bit more complex, as
you now have to check if that component is a server component (=>
already has been rendered) or a client component (=> not rendered yet,
has to be rendered here). However, this added complexity has been
alleviated through the easy-to-use `<RenderMappedComponent />` helper.
This helper now also handles rendering arrays of custom components (e.g.
beforeList, beforeLogin ...), which actually makes rendering custom
components easier in some cases.
## Misc improvements
This PR includes misc, breaking changes. For example, we previously
allowed unions between components and config object for the same
property. E.g. for the custom view property, you were allowed to pass in
a custom component or an object with other properties, alongside a
custom component.
Those union types are now gone. You can now either pass an object, or a
component. The previous `{ View: MyViewComponent}` is now `{ View: {
Component: MyViewComponent} }` or `{ View: { Default: { Component:
MyViewComponent} } }`.
This dramatically simplifies the way we read & process those properties,
especially in buildComponentMap. We can now simply check for the
existence of one specific property, which always has to be a component,
instead of running cursed runtime checks on a shared union property
which could contain a component, but could also contain functions or
objects.

- 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!
