Today we release Mojito JS Delivery v2.5.0, the latest version of our versatile JavaScript split testing library. This release focuses on improving your workflow by significantly reducing dependencies and build times through the new npm Scripts. We also introduce new container visibility enhancements to help you keep your container weight under check.

Bye to Gulp, Hello to npm Scripts​

We've replaced our aging Gulp build scripts with npm Scripts, waving goodbye to the older, aging Gulp ecosystem. This shift to npm scripts reduces dependencies by over 60% and significantly improves build times. Specifically, our Bitbucket Pipelines build times have improved by over 30%.

New Features & Updates​

• New Build Tools Suite: We've replaced the old gulp pipeline with a suite of new build tools. These npm script-based tools provide a more modern, efficient, and streamlined build process. Refer to the documentation for how the new syntax should work within your build tools.

• Improved Container Statistics: When you build your container, we now show how heavy each component and experiment is inside your container, helping you to streamline your experiments as much as possible. We also save this information and other build info to the container under the Mojito.buildInfo key for easier debugging.

• Active Development Environment: With the new npm run watch command, your container is deployed to your development environment as you actively work on experiments and files inside the container. To use this command, you'll need to be using Amazon S3 and have nodemon installed:

$ npm install -g nodemon
$ npm run watch

> mojito-js-delivery@2.5.0 watch
> nodemon --on-change-only -e js,css,yml --watch ./lib --exec npm run deploy

[nodemon] 3.0.2
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): lib/**/*
[nodemon] watching extensions: js,css,yml
[nodemon] restarting due to changes...
[nodemon] starting `npm run deploy`

> mojito-js-delivery@2.5.0 deploy
> node scripts/command.js --command deploy

Important - Breaking Changes​

Final Thoughts​

We hope these updates and features will excite you as much as we are about them. As always, feel free to share any issues or comments over on our GitHub. Happy testing and happy new year!

Note: Mojito v2.5.0 is a significant upgrade. Before updating, we recommend you thoroughly test it in your development environment.

Today we released a new minor version of Mojito JS Delivery - v2.4.0. The changes won't have a significant bearing on the contents of the split testing containers built by Mojito but it includes a significant change to the test suite, targets and build pipeline.

The changes for this version include:

The focus of this release was a series of optimisations that allowed us to cut minified container weights by a huge 0.29KB for Mojito JS Delivery. Despite the large savings, we've retained the same behaviour in the library as before.

Here's a comprehensive summary of the changes you'll find:

We've now created a new dedicated resource for Mojito documentation and guides. This site should help new and existing Mojito users with making the most out of Mojito.

We intend for this site to host resources such as:

• Getting started with Mojito
• Detailed documentation
• Mojito release announcements
• Showcasing unique usecases and the users of Mojito

To contact us, you may like to reach out to us at Mint Metrics. You can also follow / contribute to the Mojito Documentation through the website git repo here.
