Breaking Changes in 0.5.0

Global ESLint Plugin Versions

If you used a global ESLint installation for the editor integration, you’ll need to install these versions of global ESLint packages.

Moving index.html into public Folder

You’ll also need to create a new folder called public in the root of your project. Then, move index.html and files it references (such as a favicon) into that folder.

You can no longer reference any files from ./src in index.html. Instead, public/index.html can now only reference files other inside of the public folder using a special variable called %PUBLIC_URL%.

For example, instead of:

<link rel="shortcut icon" href="./src/favicon.ico">

You would need to move both index.html and src/favicon.ico into the public folder, and change <link> to look like this:

<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">

This ensures it become a part of the build output, and resolves correctly both with client-side routing and non-root homepage in package.json. Read more about using the public folder and why these changes were made.

0.4.3 (September 18, 2016)

  • You can now import jpeg, wav, mp3, m4a, aac, and oga. (@mareksuscak in #624, @danharper in #665)
  • Fixes false positives caused by the case sensitive import warning on Windows. (@Urthen in #593)

0.4.1 (September 3, 2016)

Build Dependency (react-scripts)

Migrating from 0.4.0 to 0.4.1

Inside any created project that has not been ejected, run:

npm install --save-dev --save-exact [email protected]

0.4.0 (September 2, 2016)

Migrating from 0.3.1 to 0.4.0

Inside any created project that has not been ejected, run:

npm install --save-dev --save-exact [email protected]

Breaking Change in 0.4.0

Paths like /src/somefile.png used to be served in development, but only by accident. They never worked in production builds. Since 0.4.0, we don’t serve static files by default in development anymore either. This removes a dangerous inconsistency that we never intentionally supported.

If you need a static file to be part for the build, import it from JavaScript and you will get its filename. This ensures it gets included into the production build as well, and its filename contains the content hash.

If you used static files with <link href>, read this new guide on how to make sure these files get included into the builds. For example, you can replace <link href="/src/favicons/favicon-32.png"> with <link href="./src/favicons/favicon-32.png">, and then Webpack will recognize it and include it into the build.

If you referenced some other files from index.html, please file an issue to discuss your use case. In the meantime, you can serve them from a separate static server until your use case is supported.

0.3.1 (September 2, 2016)

Build Dependency (react-scripts)

Migrating from 0.3.0 to 0.3.1

  • You can now create a project in a folder that already contains an .idea folder, which is necessary for future WebStorm integration. (@denofevil in #522)

Migrating from 0.2.3 to 0.3.0

You may optionally update the global command (it’s not required):

npm install -g [email protected]

Inside any created project that has not been ejected, run:

npm install --save-dev --save-exact [email protected]

Breaking Change

Now favicon.ico is not treated specially anymore.
If you use it, move it to src and add the following line to <head> in your HTML:

<link rel="shortcut icon" href="./src/favicon.ico">

New Feature

Since 0.3.0 added a test runner, we recommend that you add it to the scripts section of your package.json like this:

  // ...
  "scripts": {
    // ...
    "test": "react-scripts test --env=jsdom"
  }

Then read the testing guide to learn more about using it!
