Server

Our open-source server allows you to build backend-driven apps that run on your own infrastructure.

Below is the bones of an app server with user authentication built in.

// import { internalStack } from '@internalstack/server'

// const server = await internalStack('live_psk_5b2d902f24a057349d9f2d1c385fef7c59')

server.statefulSession(async(io, { user, sessionId }) => { // listening for requests
  // Business logic
})

Everytime a user loads the app's page two things happen before a request hits your app:

1. The user is authenticated/verified via email or SSO
2. The permissions are checked to make sure that user has access to your app.
3. A session is created with a unique sessionId

The server can fulfill multiple requests from multiple users while keeping track of each session's progress in-memory.

The handler function is fired whenever a page is loaded will continue it's resolution path for the length of the session.

This allows for user identity to be paired with actions for the duration of every session.

// import { internalStack } from '@internalstack/server'

// const server = await internalStack('live_psk_5b2d902f24a057349d9f2d1c385fef7c59')

server.statefulSession(async(io, { user }) => { // listening for requests
  console.log(user) // e.ripley@internalstack.com (<- Fully authenticated and authorized)
  const note = await io.input.text('Enter a note')
  console.log(note) // 'This is a note from Ellen!'

  const requestedItem = await io.input.number('Enter the name of the product to reorder')
  console.log(requestedItem) // 'Space suits'
  const requestedItemCount = await io.input.number('Enter the amount to reorder')
  console.log(requestedItemCount) // 5
})

These servers run entirely on-premises! All of your code is committed to your organization's repositories.
