Where `unplugin` gives plugins a common interface across bundlers, Devframe gives devtools a common definition and a standard way to be mounted into different environments. -## Design principles +## The shared boundary -Devframe keeps its surface focused on one tool, so the same definition stays portable across runtimes: +Most devtools — inspectors, asset viewers, build analyzers, terminals, editor integrations — rebuild the same infrastructure: server–client communication, state synchronization, serialization, static asset hosting, and a web interface. Each one also has to decide, again, how to be embedded, standalone, deployable, or integrated into a larger devtools experience. That work is usually coupled to one framework and to how its dev server serves assets, handles requests, and upgrades connections, so similar features get rebuilt separately across the ecosystem. -- **One tool per definition.** A devframe describes a single integration. Deploy it through any adapter; host-level features that only matter when several tools share a UI (palettes, cross-tool toasts, unified terminals) come from whichever host you mount into — Vite DevTools is one example. -- **Headless.** Hook into `onReady`, `cli.configure`, and friends to print your own startup banners and styling — Devframe stays out of the way. -- **App-owned file watching.** Wire your own watcher (chokidar, fs.watch, …) and signal change via `ctx.rpc.sharedState.set(...)` or event-typed RPCs. -- **Context-aware mount paths.** Standalone adapters (`cli`, `build`) serve at `/` by default; hosted adapters (`vite`, `embedded`) serve at `/./`. Override via `DevframeDefinition.basePath`. -- **SPAs own their base at runtime.** Build with relative asset paths (`vite.base: './'`); `connectDevframe` discovers the effective base from the executing script's location. -- **CLI flags compose.** The `cac` instance is exposed to both the devframe (`cli.configure`) and the caller of `createCac`, so capability flags and app flags merge cleanly. +Devframe frees a devtool from those framework-specific boundaries. A capability is defined once and can run on every supported host, so communities can improve one tool together instead of maintaining parallel versions of the same idea. -## What Devframe provides +## One definition, one standard handler -| Subsystem | What it does | -|-----------|--------------| -| **[Devframe Definition](./devframe-definition)** | One `defineDevframe` call describes your tool once; the adapters deploy it anywhere. | -| **[RPC](./rpc)** | Type-safe bidirectional calls built on birpc + valibot.

[`initDevframe()`](/adapters/initiate) turns it into a live instance whose `handler` is a Web Standard `(request: Request) => Promise`: + +```ts +import { initDevframe } from 'devframe/initiate' +import devframe from './devframe' + +const devtools = initDevframe(devframe, { base: '/__my-tool/' }) + +devtools.handler +// (request: Request) => Promise + +devtools.nodeMiddleware +// (req, res, next) => void — for Connect-style servers (Vite, Rsbuild) +``` + +Behind this handler, Devframe serves the tool's web interface, connection metadata, live RPC, authentication, and the optional MCP endpoint under one namespace. The tool is no longer tied to a particular dev-server API; its boundary is the Web Standard `Request` and `Response`. + +Modern frameworks and runtimes already converge on that boundary. Hono and Nitro work with Web Standard requests directly; Next.js and SvelteKit expose route handlers; Vite and Rsbuild accept Connect-style middleware, for which the same instance provides `nodeMiddleware`. The host still decides how the live RPC connection attaches — sharing its HTTP server, receiving its upgrade events, or using a side-car — and that choice is advertised through `__connection.json`, invisible to the client. See [The Standard Handler](/adapters/initiate) for every mount pattern. + +## Adapters as conveniences + +Mounting the handler directly is the lowest-level option. For common entry points, [higher-level adapters](/adapters/) package the same foundation into familiar forms — a standalone CLI, a dedicated dev server, a Vite DevTools plugin, an MCP server, or a static report: + +```ts +import { createPluginFromDevframe } from '@vitejs/devtools-kit/node' +import { createBuild } from 'devframe/adapters/build' +import { createCac } from 'devframe/adapters/cac' +import { createDevServer } from 'devframe/adapters/dev' +import { createMcpServer } from 'devframe/adapters/mcp' +import devframe from './devframe' + +// Pick the entry points your package ships: +export const runCli = () => createCac(devframe).parse() +export const startServer = () => createDevServer(devframe) +export const vitePlugin = createPluginFromDevframe(devframe) +export const startMcp = () => createMcpServer(devframe, { transport: 'stdio' }) +export const buildReport = () => createBuild(devframe, { outDir: 'dist-static' }) +``` + +A single package can ship several of these from one definition. A build inspector could offer a standalone CLI for any project, generate static reports in CI, appear as a dock inside Vite DevTools, and let an agent query the active build — all backed by the same tool. + +## Visual and agentic + +Once a devtool has a structured boundary, its visual panel is no longer the only interface. The same internal state and capabilities can also be consumed programmatically. Visualizations are effective for exploration, overview, and comparison; agents can retrieve focused context, correlate it with the codebase, and carry out multi-step actions. Both read from one source of truth. + +RPC functions stay private by default and explicitly opt into agent exposure. The [MCP adapter](/adapters/mcp) translates those functions, readable resources, and selected shared state into an agent-consumable surface, with descriptions, schemas, and safety metadata. See [Agent-Native](./agent-native). + +## From one devframe to a hub + +A single devframe is one portable tool. A complete devtools experience becomes more interesting when those tools meet and collaborate. [`@devframes/hub`](./hub) is the framework-neutral composition layer, providing shared concepts such as docks, commands, messages, and terminals. Each devframe runs against a shared context, so tools can contribute capabilities and interact with each other. + +The same mounting model scales to the whole collection — [`initHub()`](./hub-initiate) puts many devframes behind one Web Standard handler: + +```ts +import { createUi } from '@devframes/hub-ui' +import { DEVFRAMES_HUB_BASE, initHub } from '@devframes/hub/initiate' +import { createDataInspectorDevframe } from '@devframes/plugin-data-inspector' +import { createTerminalsDevframe } from '@devframes/plugin-terminals' + +const hub = initHub({ + base: DEVFRAMES_HUB_BASE, + devframes: [createDataInspectorDevframe(), createTerminalsDevframe()], + ui: createUi(), +}) + +hub.handler +// the whole devtools collection as Request → Response +``` + +The mounted devframes share one RPC registry, state store, connection, auth gate, and optional aggregate MCP endpoint. The hub itself is headless: [`@devframes/hub-ui`](./build-your-own-hub-ui) provides a reference interface, and a product can bring its own UI without changing the underlying tools. + +## Inheriting the ecosystem + +Portability does not make every devtool generic. Framework-specific layers can offer richer experiences because they understand their framework's conventions and runtime — the universal parts are shared while the final integrations stay specific. + +[Vite DevTools](https://devtools.vite.dev/) is the first flagship host built on this foundation, using `initHub()` for composition and serving alongside its own Vite, Rolldown, Vitest, and Oxc tooling.
