Reticle Docs: verification for AI coding agents

@reticlehq/vite-plugin is one line in vite.config.ts that does the two things everyone forgets: injecting reticle.connect() and enabling source mapping. Install it if your app builds with Vite. On Next.js use @reticlehq/next instead; on any other bundler, wire @reticlehq/browser by hand. Apache 2.0. Depends on @babel/core, @reticlehq/babel-plugin and @reticlehq/core. Optional peer dependency: vite >= 4.

Install and use

npm i -D @reticlehq/vite-plugin @reticlehq/react

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import { reticle } from '@reticlehq/vite-plugin';

export default defineConfig({
  plugins: [reticle(), react()],
});

The import specifier is @reticlehq/vite-plugin and the export is reticle. An old README documented @reticlehq/core/vite; that subpath has never existed in core’s exports map, and npx @reticlehq/core init is not a command either. The binary is reticle, from @reticlehq/server.

Why it exists

apply: 'serve' means it never reaches a production build. That is the guarantee that lets you leave it in the config permanently: there is no way to ship Reticle to your users by forgetting to remove a line.

What it injects

A virtual module at /@reticle-connect, added to the HTML, whose contents are:

import { reticle, install } from '@reticlehq/react';
install();
reticle.connect({/* resolved args */});

Plus a dynamic import of your dev module if one exists. It looks for src/reticle-dev.ts, .js, .tsx or .jsx, in that order, and leaves the file alone if you have one: that file is yours to edit.

Options

reticle(options?: ReticleVitePluginOptions): ReticleVitePlugin. Every option is optional.

Option	Type	Default
`port`	`number`	Discovered from the daemon registry for this project, falling back to `4400`
`root`	`string`	Vite’s `root`, else `process.cwd()`
`sdkVersion`	`string`	Read from the installed `@reticlehq/react`
`session`	`string`	Omitted, so the SDK generates one
`projectId`	`string`	Derived from the package name plus the root path
`token`	`string`	`readPairingToken()`, from `~/.reticle/pairing-token`
`sourceMapping`	`boolean`	`true`. Set `false` to skip the Babel pass
`inject`	`boolean`	`true`. Set `false` to call `connect()` yourself
`desktop`	`boolean`	`false`. When `true` the plugin also applies to `vite build` and passes `allowInProduction: true`, which is what an Electron or Tauri renderer needs
`captureNetworkBodies`	`boolean`	`false`. Also enabled by `VITE_RETICLE_CAPTURE_BODIES=1`
`onWarn`	`(message: string) => void`	`console.warn`

Other exports

Export	Type	What it is
`RETICLE_VITE_PLUGIN_NAME`	`'reticle'`	The plugin name
`RETICLE_TOKEN_GLOBAL`	`'__RETICLE_TOKEN__'`	The global the token is stamped onto
`RETICLE_CONNECT_MODULE`	`'/@reticle-connect'`	The virtual module id
`RENDER_PREHOOK_SOURCE`	`string`	The inline render prehook snippet
`RETICLE_DEV_MODULE_CANDIDATES`	readonly tuple	The four dev-module paths it looks for
`readPairingToken`	`() => string \| undefined`	Read the pairing token from disk
`findDevModule`	`(root: string, exists: (p: string) => boolean) => string \| null`	Locate the dev module
`connectModuleSource`	`(options: ReticleVitePluginOptions, devModule?: string \| null) => string`	Build the injected module source
`cjsDepIncludes`	`(appRoot: string, canResolve?: (dep: string) => boolean) => string[]`	CommonJS deps to add to `optimizeDeps`

Types: ReticleVitePluginOptions, ReticleVitePlugin, ViteDevServerLike.

Desktop

reticle({ desktop: true });

A packaged Electron or Tauri renderer is a production build loaded from a custom protocol, so the default guards would refuse. This one flag drops apply: 'serve' and opts the connect call into production.
