This library enables developers to quickly integrate with the VTEX IO APIs and create full fledged node services using VTEX IO.

For a complete example on using @vtex/api, check out this app: https://github.com/vtex-apps/service-example

The most basic usage is to export a new Service() with your route handlers:

// Import global types
import './globals'

import { Service } from '@vtex/api'

import { clients } from './clients'
import example from './handlers/example'

// Export a service that defines route handlers and client options.
export default new Service({
  clients,
  routes: {
    example,
  },
})

This allows you to define middlewares that receive a Context param which contains all IO Clients in the clients property:

export const example = async (ctx: Context, next: () => Promise<void>) => {
  const {state: {code}, clients: {apps}} = ctx
  console.log('Received code:', code)

  const apps = await apps.listApps()
  
  ctx.status = 200
  ctx.body = apps
  ctx.set('Cache-Control', 'private')

  await next()
}

ctx.clients.apps is an instance of Apps.

• Install the dependencies: yarn
• Watch for changes: yarn watch

• Install the dependencies: yarn
• Link this package: yarn link
• Watch for changes: yarn watch
• Move to the app that depends on the changes made on this package: cd ../<your-app>/node
• Link this package to your app's node_modules: yarn link @vtex/api

Now, when you get a workspace up and running for your app with vtex link, you'll have this package linked as well.

When done developing, don't forget to unlink it from <your-app>/node: yarn unlink @vtex/api
