Quick example

var Neo4j = require('neo4j-transactions')
 
// Create a Neo4j client instance
var client = Neo4j({
  url: 'http://localhost:7474',
  credentials: {
    username: 'neo4j',
    passwrod: 'mypassword'
  }
})
 
// If you want you can check database avaliability
// before moving on
client.databaseAvaliable
.then(function() {
  // A first call to database was successful
})
.catch(function() {
  // Database is not reachable on the provided url
})
 
// Create a transaction object
var tx = client.transaction()
 
var newPost = {
  title: 'neo4j-transactions is a tiny library',
  slug: 'neo4j-transactions-is-a-tiny-library'
}
 
// Execute a transaction which immediately commits
tx.commit([ // commit takes a list of statements
  tx.statement([
    'CREATE (post:Post)',
    'SET post = {postData}',
    'RETURN post'
  ], {postData: newPost})
])
.then(function (results) {
