graphql2cypher

Naive parser from graphql to cypher query.

main.js:

tape('user entity with address', (t) => {
  t.plan(2)
  parse(`
    user(id: <id>) {
      properties {
        name,
        address(edge: ":address", addressId: <addressId>) {
          properties {
            line
          }
        }
      }
    }
  `, (err, r) => {
    t.error(err)
    t.equals(r.cql, expected)
  })
  var expected = `
    match(user:user {id: {id}}) optional match(user)<-[:address]->(address:address {addressId: {addressId}})
    return *
  `
})

To see how reduce works to see how it looks check out fixtures, It works together with the module cypherquery

relationships, labels and graph

This requires that the statement sent to cypher has resultType ['row', 'graph']]

`
    user(id: <id>) {
      relationships,
      ...
`

labels

You can ask for labels in graphql

`
    user(id: <id>) {
      labels
      ...
