HOW TO KEEP JAVASCRIPT BUILDS FAST

SLOW BUILDS QUIETLY DRAIN PRODUCTIVITY. A FEW SMART HABITS CAN CUT WAITING TIME FROM MINUTES TO SECONDS.

As projects grow, build times often creep up until every small change feels expensive. The good news is that most of the delay comes from a handful of common causes.

MEASURE BEFORE YOU OPTIMISE

Use your bundler's analysis tools to see which dependencies and steps take the longest. Large libraries, duplicated packages and unnecessary transforms are usually the first things to fix.

USE MODERN TOOLING

Newer bundlers and compilers written in faster languages can make builds dramatically quicker. Combine them with caching in your CI pipeline so unchanged code is never rebuilt twice.

FASTER BUILDS MEAN MORE EXPERIMENTS, QUICKER FEEDBACK AND HAPPIER DEVELOPERS.

SHIP LESS CODE

Split bundles by route, lazy-load heavy components and remove unused code. Smaller bundles build faster and load faster for your visitors too.
