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',
    ],
  },
})
