single-spa/single-spa v3.0.0

Version 3.0.0

on GitHub

Breaking changes:

• The pause and unpause apis have been removed
• single-spa doesn't mount, or unmount applications until the new start API is called. However, it does load and bootstrap them before start is called.
• The setLoader api now must be called. And it must be called before any declareChildApplication or start apis are called.

Features

• The "main" file is now a distributable which can be used via <script>, npm/commonjs (require), and systemjs.
• Tests now run in IE11, Chrome, Firefox, Edge, and Safari via karma + saucelabs. This is an improvement over just running in node with a mocked DOM and browser.
• Loading and bootstrapping before start() is now possible, which yields a performance boost.
• Apps that are going to be mounted no longer wait for all other apps to load/bootstrap before beginning to mount. This improves performance.

Issues fixed

• Fixed #4 (code quality of single-spa project)
• Fixed #64 (performance)

Concerns

• Because the main file is now a bundle with no dependencies and because I'm using async/await babel plugin, the size of the distributable has ballooned to 64kb. I think we can address that after releasing 3.0
