I've been using create-react-app in conjunction with lerna repos and for the most part its been an awesome experience. The one issue I've been seeing is when trying to issue lerna run test commands to test all packages that have a "test" script. Since create-react-app defaults to entering watch mode on test, it hangs.

Read the migration guide to learn how to enable it in older projects! Create React App uses Jest as its test runner. To prepare for this integration, we did a major revamp of Jest so if you heard bad things about it years ago, give it another try. Jest is a Node-based runner. This means that the tests always run in a Node environment and not in a real browser. This lets us enable fast iteration speed and prevent flakiness. While Jest provides browser globals such as window thanks to jsdom , they are only approximations of the real browser behavior. Jest is intended to be used for unit tests of your logic and your components rather than the DOM quirks. We recommend that you use a separate tool for browser end-to-end tests if you need them. They are beyond the scope of Create React App. For example, if App. Collocation also helps find tests more quickly in larger projects.

The error sounds like something has gone wrong with the build.

Webpack can watch files and recompile whenever they change. This page explains how to enable this and a couple of tweaks you can make if watching does not work properly for you. Turn on watch mode. This means that after the initial build, webpack will continue to watch for changes in any of the resolved files. Add a delay before rebuilding once the first file changed. This allows webpack to aggregate any other changes made during this time period into one rebuild.

Alternatively, you can learn how to create a React app from scratch, using Webpack to build and watch the files, and Babel to transpile the React to JavaScript. You switched accounts on another tab or window. Is that the current situation or have I missed some completely obvious way of doing this? The plan would be that react would gradually expand to the rest of the app if needed, maybe it'd never be needed. This is an optimization designed to make your tests run fast regardless of how many tests you have. Thanks gaearon and ryansully. If progress shows on save but no files are outputted, it is likely a configuration issue, not a file watching issue. This was referenced Feb 23, How to run build in watch mode Also, I notice you do not import React in App. No tests found related to files changed since the last commit No tests found related to files changed since the last commit. This would be a very nice feature!! This could potentially cause problems with the system's file watching mechanism. I actually deleted it because in the youtube video which is from freeCodeCamp by CodingAddict also deleted them.

To customize most things when using Create React App , you can eject. However, you'll then need to maintain every configuration and script yourself, which can be a bit annoying. By doing this you're breaking the "guarantees" that CRA provides.

I don't understand why there is no debug build, seriously, I have not seen any compiler that forces you to build optimized builds only Make a script for npm build-dev From this, cross-env is one solution, but running npm test -- --coverage also only runs tests once, and avoids the need for another dependency unless you already have need for it for other reasons. Any way to resolve that? This was referenced Feb 11, Watch and WatchOptions Webpack can watch files and recompile whenever they change. CRA is quite appealing to non Node. But CRA appears to assume that in development mode, your frontend is a different app from your backend. I understand the frustrations, but all I can see is:. And to be honest, these days it's way more difficult to set up a React project than an ember or angularjs 1. We hope we could show you how easy it is to create code coverage during Continuous Integration and to keep an eye on it over time. You signed in with another tab or window.
