Object-to-graph mapper for Node.js which speaks Gremlin (and also reads .groovy files).
Most of the documentation is found in the wiki.
Comments, suggestions and pull requests are welcome.
$ npm install mogwai
Please refer to grex's documentation first on how to set up your Graph database/Rexster server (ie. you will have to install Gremlin and Batch kibbles).
Note that installing Batch kibble will no longer be necessary in a future version of Mogwai.

Simple Schema Definition

The full documentation is available in the Github wiki.
Mogwai's API is currently inspired by two libraries:
- Mongoose (see documentation), a MongoDB modeling library for Node.js, especially for the general design of the library (Schema, Models, plugins, etc.). Hence, some method names in Mogwai are very inspired by MongoDB's method (ie.
- Bulbflow (see Github repo), "a Python persistence framework for graph databases", especially for all stuff related to loading Gremlin scripts defined in .groovy files.
Mogwai sends Gremlin code/queries via HTTP directly to a Rexster server with the Gremlin extension enabled. Note that Mogwai currently also uses some features from grex, a "Gremlin inspired Rexster Graph Server client", which requires the Batch extension on your Rexster server as well.
Mogwai also aims to be ready for changes coming next year with Tinkerpop 3.0. Mogwai may support Rexpro in the future.
Note that Mogwai is currently developed with TitanDB v0.4.0 only, and hasn't been tested with other Tinkerpop/Rexster compliant databases. Although most features should work, expect some of them to not work at all (ie. the still partially supported indexes). Feel free to fork and send a pull request (see
/src/clients if you wish to tweak/implement client classes).
Please be aware that Mogwai is in active development, so changes breaking backward compatibility are very likely to occur as this project evolves to a more mature/stable API.
Mogwai is not considered stable and should not be used in production. Use at your own risk.
Install development dependencies
$ npm install
then run tests
$ make test
- More work on indexes (support more databases)
- Schema: defining property types, indexes, etc.
- Hooks (pre and post middlewares)
- Getters and setters for properties
- Write many more tests
- Performance and optimization
