Quick Start

Create Client Instance

const { API, cond, or, and } = require('space-api-node');

const api = new API('demo-project');

// For MongoDB
const db = api.Mongo();

// For PostgresQL
const db = api.Postgres();

// For MySQL
const db = api.MySQL();

Note: Multiple databases may be used simultaneously.

Insert a document into the database

const doc = {_id: 1, title: "Title 1", content: "My first record"};
db.insert('COLLECTION_NAME').one(doc).then(res => {
  if (res.status === 200) {
    // Document inserted successfully
    return;
  }
}).catch(ex => {
  // Exception occured while processing request
});

Note: Always insert documents with a id in order to use the realtime feature.

Query documents in database

const find = and(cond('title', '==', 'Title1'), cond('author', '==', 'Jon'));
db.get('COLLECTION_NAME').where(find)
  .skip(10).limit(10)
  .all()
  .then(res => {
    if (res.status === 200) {
      // res.data contains the documents returned by the database
      console.log('Response:', res.data);
      return;
    }
  }).catch(ex => {
    // Exception occured while processing request
  });

Update documents in database

const find = and(cond('author', '==', 'Jon'));
db.update('COLLECTION_NAME').where(find)
  .set({ author: 'John' })
  .all()
  .then(res => {
    if (res.status === 200) {
      // Document updated successfully
      return;
    }
  }).catch(ex => {
    // Exception occured while processing request
  });

Delete documents in database

const find = and(cond('author', '==', 'John'));
db.delete('COLLECTION_NAME').where(find)
  .many()
  .then(res => {
    if (res.status === 200) {
      // Document deleted successfully
      return;
    }
  }).catch(ex => {
    // Exception occured while processing request
  });

Get real time updates

const onSnapshot  = (snapshot, type, docs) => {
  if (type === 'monitor') {
    console.log('Monitored successfully ', snapshot)
      return
    }
    console.log(type, snapshot, docs)
   }
 
const onError = (err) => {
  console.log('Monitor error', err)
}
 
let unsubscribe = db.monitor('posts').where().subscribe(onSnapshot, onError) 
 
unsubscribe()

Call functions directly (Function as a Service)

api.call('my-engine', 'my-func', { msg: 'Function as a Service is awesome!' }, 1000)
  .then(res => {
    if (res.status === 200) {
      console.log('Response: ', res.data)
    }
  }).catch(ex => {
    // Exception occured while processing request
  })
