# Mithril.js - A framework for building brilliant applications
|
|
|
|
[Documentation](docs) | [Migration Guide](docs/v1.x-migration.md)
|
|
|
|
Note: This branch is a sneak peek for the upcoming version 1.0. It's a rewrite from the ground up and it's not backwards compatible with [Mithril 0.2.x](http://mithril.js.org). You can find preliminary [documentation here](docs) and [migration guide here](docs/v1.x-migration.md)
|
|
|
|
This rewrite aims to fix longstanding API design issues, significantly improve performance, and clean up the codebase.
|
|
|
|
## Early Preview
|
|
|
|
You can install this via NPM using this command:
|
|
|
|
```
|
|
npm install lhorie/mithril.js#rewrite
|
|
```
|
|
|
|
Examples run out of the box. Just open the HTML files.
|
|
|
|
## Status
|
|
|
|
The code is fairly stable and I'm using it in production, but there may be bugs still lurking.
|
|
|
|
Some examples of usage can be found in the [examples](examples) folder. [ThreadItJS](http://cdn.rawgit.com/lhorie/mithril.js/rewrite/examples/threaditjs-bundle/index.html) has the largest API surface coverage.
|
|
|
|
Partial documentation can be found in the [`/docs`](docs) directory
|
|
|
|
## Performance
|
|
|
|
Mithril's virtual DOM engine is around 500 lines of well organized code and it implements a modern search space reduction diff algorithm and a DOM recycling mechanism, which translate to top-of-class performance. See the [dbmon implementation](http://cdn.rawgit.com/lhorie/mithril.js/rewrite/examples/dbmonster/mithril/index.html) (for comparison, here are dbmon implementations for [React v15.0.2](http://cdn.rawgit.com/lhorie/mithril.js/rewrite/examples/dbmonster/react/index.html), and [Angular v2.0.0-beta.17](http://cdn.rawgit.com/lhorie/mithril.js/rewrite/examples/dbmonster/angular/index.html). All implementations are naive (i.e. apples-to-apples, no optimizations)
|
|
|
|
## Robustness
|
|
|
|
There are over 4000 assertions in the test suite, and tests cover even difficult-to-test things like `location.href`, `element.innerHTML` and `XMLHttpRequest` usage.
|
|
|
|
## Modularity
|
|
|
|
Despite the huge improvements in performance and modularity, the new codebase is smaller than v0.2.x, currently clocking at 7.2kb min+gzip
|
|
|
|
In addition, Mithril is now completely modular: you can import only the modules that you need and easily integrate 3rd party modules if you wish to use a different library for routing, ajax, and even rendering
