-+ * Overleaf request-input lockdown.
-+ *
-+ * Captures parsed request input in symbol-keyed fields and, when
-+ * REQ_LOCKDOWN_MODE is 'warn' or 'throw', turns the public req.body,
-+ * req.query and req.params properties into lockdown accessors:
-+ *
-+ *  - reads log a warning ('warn' mode) or throw ('throw' mode); request
-+ *    input must be read through parseReq() from @overleaf/validation-tools,
-+ *    which validates it against a zod schema, or through getRawReqInput()
-+ *    for allowlisted middleware
-+ *  - writes always work and are stored in the symbol-keyed fields, so body
-+ *    parsers and middleware that assign req.body keep functioning unchanged
-+ *
-+ * With REQ_LOCKDOWN_MODE unset (or 'off') nothing is installed and express
-+ * behaves exactly like the unpatched package.
-+ *
-+ * The symbols are registered in the global symbol registry so that
-+ * @overleaf/validation-tools can read the raw fields without importing
-+ * express internals. Express' own internals (router param processing, the
-+ * query middleware, res.jsonp) go through the helpers below instead of the
-+ * public properties so that only application code trips the lockdown.
-+ *
-+ * Note: unlike the stock properties, the locked accessors are defined
-+ * non-enumerable so that iterating/serializing a request (e.g. in logging)
-+ * does not trip the lockdown.

+# Overleaf Community Edition, development environment
+
+## Building and running
+
+In this `develop` directory, build the services:
+
+```shell
+bin/build
+```
+
+> [!NOTE]
+> If Docker is running out of RAM while building the services in parallel, create a `.env` file in this directory containing `COMPOSE_PARALLEL_LIMIT=1`.
+
+Then start the services:
+
+```shell
+bin/up
+```
+
+Once the services are running, open <http://localhost/launchpad> to create the first admin account.
+
+## Development
+
+To avoid running `bin/build && bin/up` after every code change, you can run Overleaf
+Community Edition in _development mode_, where services will automatically update on code changes.
+
+To do this, use the included `bin/dev` script:
+
+```shell
+bin/dev
+```
+
+This will start all services using `node --watch`, which will automatically monitor the code and restart the services as necessary.
+
+To improve performance, you can start only a subset of the services in development mode by providing a space-separated list to the `bin/dev` script:
+
+```shell
+bin/dev [service1] [service2] ... [serviceN]
+```
+
+> [!NOTE]
+> Starting the `web` service in _development mode_ will only update the `web`
+> service when backend code changes. In order to automatically update frontend
+> code as well, make sure to start the `webpack` service in _development mode_
+> as well.
+
+If no services are named, all services will start in development mode.
+
+## Debugging
+
+When run in _development mode_ most services expose a debugging port to which
+you can attach a debugger such as
+[the inspector in Chrome's Dev Tools](chrome://inspect/) or one integrated into
+an IDE. The following table shows the port exposed on the **host machine** for
+each service:
+
+| Service            | Port |
+| ------------------ | ---- |
+| `web`              | 9229 |
+| `clsi`             | 9230 |
+| `chat`             | 9231 |
+| `docstore`         | 9233 |
+| `document-updater` | 9234 |
+| `filestore`        | 9235 |
+| `notifications`    | 9236 |
+| `real-time`        | 9237 |
+| `history-v1`       | 9239 |
+| `project-history`  | 9240 |
+| `linked-url-proxy` | 9241 |
+
+To attach to a service using Chrome's _remote debugging_, go to
+<chrome://inspect/> and make sure _Discover network targets_ is checked. Next
+click _Configure..._ and add an entry `localhost:[service port]` for each of the
+services you want to attach a debugger to.
+
+After adding an entry, the service will show up as a _Remote Target_ that you
+can inspect and debug.

-/**
- * cypress-multi-reporters, loadable from inside Cypress.
- *
- * Cypress builds mocha reporters in its Electron process. That process resolves
- * modules through PackherdModuleLoader and does not inherit NODE_OPTIONS, so
- * Yarn PnP is not installed there and `require('cypress-multi-reporters')`
- * fails with "Cannot find module".
- *
- * Installing PnP for the rest of that process is not an option either: Cypress
- * asks packherd for its own bundled modules under ids like
- * `packages/server/lib/browsers/`, which PnP reads as paths inside this
- * workspace and then rejects ("it isn't declared in your dependencies"),
- * breaking the browser launch.
- *
- * So install PnP, pull the reporters in through it, and hand resolution back to
- * Cypress. Requires made by the modules that came in through PnP keep going
- * through PnP, so anything they load later still resolves.
- *
- * Point Cypress at this package rather than at cypress-multi-reporters:
- *
- *   reporter: require.resolve('@overleaf/cypress-pnp-reporter')

- * to look it up, and every store that did was paying a lookup -- a database query,
