LABjs is a dynamic JavaScript script loader that loads all scripts in parallel while allowing explicit execution-order dependencies via a chained .wait() API. It was designed to replace blocking <script> tags with a performance-optimized loading approach for the browser.
Use cases
- load javascript files in parallel in the browser
- control script execution order with dependencies
- speed up page load by avoiding blocking script tags
- chain inline scripts to run after loaded scripts
- optimize legacy website script loading performance
When to choose
- maintaining an older codebase that already uses LABjs
- supporting very old browsers where native async/defer handling is unreliable
- you need fine-grained parallel loading with explicit execution-order control
When to avoid
- starting a new modern project - use native ES modules, async/defer, or a bundler instead
- you need actively maintained software - the repo was archived in 2022
- you rely on modern module bundling or tree-shaking workflows
