Notes

The middleware property on the options param is useful for applying universal middleware such as CORS headers or Auth, across an entire API from a single place.

Examples

Create an API

import { api } from '@nitric/sdk'
const publicApi = api('public')

Create an API with universal middleware

import { api } from '@nitric/sdk'
import { authMiddleware } from '../middleware'
const privateApi = api('private', { middleware: authMiddleware })

Define middleware

const authMiddleware = async (ctx, next) => {
// Perform auth validation.
return await next(ctx)
}

Notes

Middleware services are supplied an HttpContext object and a next() function which calls the next middleware in the chain.

Create an API with a base path

If you need to put all the routes in your api below a shared base path, you can do that with the path option. In this example we ensure all routes start with /api/v1/ before the route specific path.

import { api } from '@nitric/sdk'
const apiV1 = api('private', { path: '/api/v1' })

Apply JWT authentication to an API

import { api, jwt } from '@nitric/sdk'
const secureApi = api('secure', {
// security requirements for your API are defined here
securityDefinitions: {
// define a security definition called 'user'
user: jwt({
issuer: 'https://example-issuer.com',
audiences: ['YOUR-AUDIENCES'],
}),
},
// You can optionally apply security rules to the entire API
security: {
// apply the 'user security definition the whole API'
user: [
// Optionally apply required scopes to this api
// in this case users will require the products:read scope to access the API
'products:read',
],
},
})
