v2.2.0

New in this release:

• customizeWebpackConfig can now return a promise, to allow for asynchronously constructing the result.
• new jsdomOptions config, to allow for configuring the underlying JSDOM instance.
• plugins can now specify their own publicFolders

v2.1.1

Fixes a bug where certain webpack build errors would be swallowed and surfaced as "Could not load script" instead of showing the build failure.

Also makes it possible to use happo.io with @babel/preset-react for Babel 7. Before, happo would fail trying to use babel-preset-react (which is only compatible with babel <6).

v2.1.0

Changes:

• New configuration option, tmpdir, allows you to control where happo creates its webpack bundles. This can be useful when debugging things.

v2.0.0

Breaking changes:

• webpack is now a peer dependency, and we allow both webpack v3 or v4 to be used. If you're upgrading to happo.io v2 from v1, you need to make sure webpack is in the list of dependencies for your project.

Enhancements:

• Happo plugins are born, the first one being happo-plugin-storybook that can be used to turn storybook examples into happo examples.

Bug fixes:

• In React projects, components are now unmounted after being rendered. This fixes memory issues we've seen in larger projects.

v1.5.1

• Log something when fallback auth is used (to help debug authentication issues)

v1.5.0

Changes:

• Adds ability to skip api tokens (apiKey, apiSecret) in a pull request model. This will make it possible to run Happo tests on PRs coming from forks of a repo. Requires the Happo app to be installed, and activated on the account on happo.io.

(Some pending updates to the happo.io are required for this to fully work.)

v1.4.0

Changes in this version:

• Improvements to CLI logging (colors, structure)
• All render failures are now collected before failing run

v1.3.0

Changes in this release:

• babel-core and babel-loader have been made peerDependencies.

v1.2.1

• Fixes issues with rendering portal components in React.
• Updates a few dependencies

v1.2.0

The main change in 1.2.0 is that the direct dependency on React has been removed. It is still the default, but you can now also create plain js projects, so anything that can render html in javascript should now be covered.

Other changes worth mentioning:

• Better error messages. Instead of seeing an error in an eval, you now see the component and variant where the error happened, plus a location in a js file (this is still the tmp file which isn't ideal, but better than nothing).
• Better default webpack config. Many projects can now ditch the customizeWebpackConfig configuration option.
• Use type: 'plain' to not use react.
• A simple requestAnimationFrame polyfill will silence warnings from React
• Don't fail when publicFolders is missing (and there is a resource to inline)
• CSS url()s are now also inlined if needed. Images in html were already inlined.
• stylesheets can now be file paths as well as urls.
