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.

See comment for a discussion which leads to the creation of this issue. I propose adding a new command working name build-dev which watches for changes and rebuild the bundle effectively, given the current CRA implementation, it should execute webpack --watch , then writes it onto filesystem. The main motivation is an easier integration path with non-Node. The only desired configuration options is an --output , which could probably be specified via a command line argument:. The text was updated successfully, but these errors were encountered:. My concern: the concept of a dev server is already confusing to many people and I've seen countless issues from people trying to find dev server output in the filesystem, adding scripts with hrefs to local files, when they didn't need it. So I'm worried introducing this feature is useful in some advanced cases but might make everything more confusing in simple cases for people who mistakingly start with build-dev instead because they haven't seen a dev server before when dev server is exactly what they need.

It does not necessarily need to be named App. Jest will always run all tests on a continuous integration server or if the project is not inside a Git or Mercurial repository.

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.

It'd be very awesome if craco automatically watched for changes to craco. The text was updated successfully, but these errors were encountered:. Hi devinrhode2. Sorry, something went wrong. Do you think it'd be possible to write a plugin that watches craco.

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.

Both of those should cover my needs. Still feels against the norm to me for npm test to run tests in watch mode. The default configuration that Create React App uses for Jest can be overridden by adding any of the following supported keys to a Jest config in your package. The main problem with trying to use Express with create-react-app is that react-scripts start doesn't output anything so there's nothing to serve with Express in development mode with hot reload. Now we are done. 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. The text was updated successfully, but these errors were encountered:. Wow, this is old. Pass a value in milliseconds:. Hello there, Just my best guess: HMR is not watching index. There is no any error showing in console. Travis, Circle, and probably others already do this. Thanks for your reply. This lets us enable fast iteration speed and prevent flakiness.

Even though many helper extensions exist out there on VSCode to address the "dot-dot-slash recursive hell", the relational paths are painful to write if you have a folder structure with multiple layers. You may see some projects that are using absolute paths, and it looks cool right? So, why not?

See this article. Does it work with the second link the one after On Your Network? Support for staging builds Further, npm test is commonly used in CI processes in the context of it being a single run without needing to set an environment variable.

When you use create-react-app it includes some special scripts that encapsulate much of the normal activities, such as starting a development server and running tests. That is, it could be specifically excluded from the watch directory. There are a variety of reasons why webpack might miss a file change. POC of providing a watching build mode that writes to the disk in development The default configuration that Create React App uses for Jest can be overridden by adding any of the following supported keys to a Jest config in your package. Have a question about this project? Here is a stackoverflow issue about the problem you are facing: I would however suggest you to create a fresh installation of Create-react-app in a different folder, and see if the problem is solved by doing that.
