var Neo = require('neo4j-qb');

var qb = Neo(host, username, password, options);

```

```javascript

// CREATE (:User {name: 'Jhon'})

qb.insert({ name: 'Jhon' }, 'User').then(...)

// MERGE (:User {name: 'Jhon'})

qb.upsert(null, { name: 'Jhon' }, 'User').then(...);

// MERGE (n:User {name: 'Jhon'}) ON CREATE SET n.email = '[email protected]' ON MATCH SET n.email = '[email protected]'

qb.upsert({ email: '[email protected]' }, { name: 'Jhon' }, 'User').then(...);

```

### Match

```javascript

// MATCH (u:User {id: 1}) RETURN n.id

qb.match('User', { id: 1 }, 'u').fetch('n.id').then(...);

// MATCH (u:User)-[f:FRIEND_OF]->(u2:User) WHERE u.name = 'Jhon' RETURN f.since

qb.path(function (q) {

  q.node('User', 'u').rrel('FRIEND_OF', 'f').node('User', 'u2');

})

.where('u.name', '=', 'Jhon')

.fetch('f.since');
