swagger-autogen to nodox-cli
swagger-autogen requires JSDoc comments on every route. nodox-cli reads your existing validator schemas automatically, no comments, no YAML, no extra files to maintain.

The JSDoc problem
swagger-autogen's core mechanic is scanning your source files for JSDoc comments that describe your API. That means every route needs a comment block like this:
swagger-autogen — what you have to write per route
/**
* #swagger.tags = ['Users']
* #swagger.description = 'Create a new user'
* #swagger.parameters['body'] = {
* in: 'body',
* description: 'User data',
* required: true,
* schema: {
* $name: 'Alice',
* $email: 'alice@example.com',
* age: 28
* }
* }
* #swagger.responses[201] = {
* description: 'User created',
* schema: { $id: 1, $name: 'Alice', $email: 'alice@example.com' }
* }

app.post('/users', handler)nodox-cli — what you write
app.use(nodox(app)) // ← this is it
app.post('/users', validate(CreateUserSchema), handler)
// Swagger docs appear at /__nodox automatically.Migration from swagger-autogen
If you're already using swagger-autogen, switching takes about 5 minutes:
- Run
npm install nodox-cli - Add
app.use(nodox(app))before your routes - Wrap any inline validators with
validate(schema)for confirmed schemas - Remove your swagger-autogen JSDoc comments (or leave them; nodox ignores them)
- Delete your swagger-autogen build script and generated
swagger-output.json
Your docs are now live at /__nodox with zero build step.
