On my build step I'm using babel to transpile the code to es5 (from src to dist). How do I make it exclude files ending in .test.js?
package.json
"scripts": { "build": "babel src --out-dir dist", .babelrc
{ "presets": [ "es2015" ], "ignore": "\\.test\\.js" }

The . babelrc file is your local configuration for your code in your project. Generally you would put it in the root of your application repo. It will affect all files that Babel processes that are in the same directory or in sibling directories of the . babelrc .
Babel is a toolchain that is mainly used to convert ECMAScript 2015+ code into a backwards compatible version of JavaScript in current and older browsers or environments.
@babel/preset-env is a smart preset that allows you to use the latest JavaScript without needing to micromanage which syntax transforms (and optionally, browser polyfills) are needed by your target environment(s). This both makes your life easier and JavaScript bundles smaller!
Based on the documentation, you should be able to write .babelrc
{ "ignore": [ "**/*.test.js" ] } However, I was able to verify that this does not seem to work. I tried it with version 6.5.1 (babel-core 6.5.2).
At the same time, the following does work:
babel src --out-dir build --ignore '**/*.test.js' That is the same glob pattern as written in the .babelrc file. If you install any glob library from npm you'll find that this glob pattern would work (that is how I came up with it...I do not currently use babel).

As of today, the following works in .babelrc (babel-core: v6.26.3)
"ignore": [ "**/__tests__", // ignore the whole test directory "**/*.test.js" // ignore test files only ] If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
