Here we are talking about solutions to build web applications from the back-end side (including the database and the web server) to the front-end layer using only one language (JavaScript).

Let's face the truth: unlike other categories like front-end frameworks, there are very very few contenders in this category where Meteor is the king. We could mention DerbyJS as a contender but it has little traction.

Interest - satisfaction

In this category, Meteor is the pionner, with an active community and a strong eco-system, so it's not a surprise that it's known by 90% of people who anwsered the survey.

Meteor may be the most popular solution (more than 35,000 stars on Github), the "MEAN" (Mongo + Express + AngularJS + node.js) stack was used by almost twice more users in our survey (3000 vs 1700).

GOAL: display the list of projects from bestof.js.org

├── index.html
