Why we chose Loopback over Sails and Meteor

The Context for using Loopback for our application

One of the first things we do in a typical Node.js project is to pick the appropriate Node framework from the plenty of choices available. Good thing – Lots of choices; Bad thing – Fragmented efforts and no framework with real momentum.

Our decision framework

We took a typical polyglot approach to a technology stack. The platform has 2 main components: one for intelligence (Data Crunching, Machine Learning, Text Analytics and so on). For this we finalized a stack of LUIGI, Elastic search, Spark, R and Python with a little bit of MongoDB thrown in.

The second part of the platform is a typical business web application to expose output of the intelligent platform, business workflows etc.,

For this, we decided on Node.js because it lend itself well for micro-services architecture. Some of our UI is message driven. Having decided on Node.js, we needed a web application framework (if you are only looking for an API backend, there are other good options like http://senecajs.org/) for rapid application development. Some of our selection criteria were

  • Integrated a la Rails
  • Quick CRUD development
  • Automatic API generation from CRUD
  • Good horizontal starter functionality
  • Integrated build, deploy, debug, monitor capability
  • Critical mass adoption
  • Ability to get to barebones node when needed
  • Embedded socket.io for push messaging
  • Decent ORM with auto managed associations etc
  • Not tied to a front end framework as we want to use React
  • Isomorphic Javascript compatible

We considered the following frameworks:

  • Sails.js
  • Loopback
  • Total.js
  • Koa.js
  • Meteor.js
  • mean.io/mean.js

Unfortunately, in Node.js web framework landscape there is no one clear winner with mass adoption unlike for Rails for Ruby or Django for Python. There are lot of fragmentation with each framework having some nice features but with very little adoption.

The choices (Meteor vs. Sails vs. Loopback)

After the initial research, we quickly dropped Total.js and Koa.js because of considerations like lack of momentum, the strength of the organization behind it etc.

We quickly dropped mean.io and mean.js because they are tightly married to Angular and retrofitting React is a lot of work.

We gave more consideration to Meteor as it has nice features like:

  • Fully integrated tool chain
  • Very easy data to front end binding etc

But dropped it because the choice meant that we couldn’t have a pure Node.js runtime. Besides it was too opinionated, doesn’t play nice with non-meteor specific third party components. Also, the front end was not switchable.

Then it boiled down to Sails and Loopback. Sails had the most adoption and Loopback had the most recent momentum.

Sails it is. Sails it isn’t.

We picked Sails because of the maturity, adoption, good documentation, availability of many useful plugins and our developer knowledge.

Sails:

5438 commits, 23 branches, 173 releases, 195 contributors

Loopback:

1705 commits, 44 branches, 95 releases, 62 contributors

But quickly switched to Loopback because of 2 events.

The Sails team have fragmented with most of the developers going to start a competing framework Trails.js (read this discussion: shit hit the roof. Also, though Sails had some decent GitHub statistics, when we delve deeper most of it turned to be cosmetic changes like read-me updates.

The fallback to Loopback

Finally, we decided to go with Loopback:

  • Isomorphic model definitions
  • Strong support for API creation – plays well with our Microservices strategy
  • Clean separation between API server and client
  • Baked in mobile client SDKs
  • Powerful ACLs
  • Secure with baked in cross XSS
  • Good core code quality
  • Good suite of surrounding tools like StrongLoop Arc, visual API composer, CLI code generators etc.
  • Great recent momentum
  • Pedigree of the core developers
  • Commercial tools from StrongLoop which gives them a business incentive to keep investing into LoopBack

IBM has acquired StrongLoop which will only increase the commitment to the commercial suite of products and keep the dedicated team working on Loopback funded. And IBM has a good track record of contributing to open source projects like Apache Spark, Cloud foundry etc.
