ArangoDB JavaScript Driver 3.7: Promises and Performance

ArangoJS, the official ArangoDB JavaScript client, has been updated to version 3.7.0. The new release features significant performance improvements in Node.js and io.js. The dependency on the third-party request module has been replaced with a thin wrapper around node’s own http module, bringing a 3-4x performance improvement for consecutive requests by maintaining a connection pool.

The earlier 3.5 release also added optional support for ES6 promises. While ArangoJS does not provide a promise implementation itself, all asynchronous methods now return promises in JavaScript environments that support them – whether natively (e.g. in io.js or modern browsers) or using a polyfill like es6-promise.

The latest version of ArangoJS is available on NPM and GitHub.
