gremlin-template-string
Generate Gremlin scripts with bound parameters using ES6 template strings.
Gremlin is a graph database query language used by the Apache TinkerPop framework.
Read the full Gremlin/TinkerPop3 documentation there: http://www.tinkerpop.com/docs/current/
Install
$ npm install gremlin-template-string --save
Run tests with:
$ npm test
Usage
The module exports a single function (tag expression) which allows you to tag an ES6 template template string.
It will return an object with two properties:
script
: an escaped Gremlin stringparams
: a map (Object) of bound parameters (ie{p1: 'Foo', 'p2': 'Bar'}
)
Example
var gremlin = require('gremlin-template-string');
var who = 'Foobar';
var query = gremlin`
g.V('name', ${who}).out('follows').name
`
// query.script === "\n g.V('name', p1).out('follows').name\n"
// query.params.p1 === 'Foobar'
Benefits
- easy multiline Gremlin queries
- syntax highlighting in IDE (Sublime Text)
- safer scripts (prevents Gremlin injections)
- faster scripts (bound parameters)
