Email Signin

You can easily allow users to log in to your app via email using the db.signIn function. This is how you could add a simple log in feature in your app. Make sure you have enabled the auth module. Here’s a code snippet to implement basic email sign in:

import { API } from 'space-api';

// Initialize api with the project name and url of the space cloud
const api = new API('todo_app', 'http://localhost:4122');

// Initialize database(s) you intend to use
const db = api.DB("mydb");

// SignIn
db.signIn('', '1234').then(res => {
  if (res.status === 200) {
    // Set the token id to enable operations of other modules
    // contains request payload
  // Request failed
}).catch(ex => {
  // Exception occured while processing request

As you would have noticed, the above function is asynchronous in nature. The signIn method takes 2 parameters:

  • email - Email of the user.
  • pass - Password of the user.


On getting the log in request, Space Cloud validates whether such an user exists and sends a response accordingly. A response object sent by the server contains the status and data fields explained below.

status: Number describing the http status code of the response. Following values are possible:

  • 200 - Successful sign in
  • 404 - No user with the given email
  • 401 - The given credentials are not correct
  • 500 - Internal server error

data: The data object consists of the following fields:

  • token - The JWT token generated by the authentication module. The token contains the following claims - id (the unique id for the user), role and email
  • user - Row / document corresponding to the signed in user

The next step would be checking out the client reference to register a new user.
