  • Breaking change: instead of

    

    • 



<AppContainer component={App} props={{ prop: val }} />



  you now need to write

  ```js
  <AppContainer>
    <App prop={val} />
  </AppContainer>



(#250)


See this commit as an update reference!


3.0.0-alpha


Big changes both to internals and usage. No docs yet but you can look at gaearon/react-hot-boilerplate#61 for an example.


2.0.0-alpha


Experimental release that isn't really representative on what will go in 2.0, but uses the new engine.


Some ideas of what should be possible with the new engine:


    

  • There is no requirement to pass getRootInstances() anymore, so React Hot Loader doesn't need react/lib/ReactMount or walk the tree, which was somewhat fragile and changing between versions
    • 

  • Static methods and properties are now hot-reloaded
    • 

  • Instance getters and setters are now hot reloaded
    • 

  • Static getters and setters are now hot reloaded
    • 

  • Deleted instance methods are now deleted during hot reloading
    • 

  • Single method form of autobind-decorator is now supported
    • 



What might get broken:


    

  • We no longer overwrite or even touch the original class. Every time makeHot is invoked, it will return a special proxy class. This means a caveat: for example, static methods will only be hot-reloaded if you refer to them as this.constructor.doSomething() instead of FooBar.doSomething(). This is because React Hot Loader calls makeHot right before exporting, so FooBar still refers to the original class. Similarly, this.constructor === App will be false inside App unless you call App = makeHot(App) manually, which you can't do with React Hot Loader. I'm not sure how much of a problem this will be, so let me know if it pains you. In the longer term, we will deprecate React Hot Loader in favor of a Babel plugin which will be able to rewrite class definitions correctly, so it shouldn't be a problem for a long time. If there is demand, we can introduce a mode that rewrites passed classes, too.
    • 



1.3.1


    

  • Fix import for ReactMount to support 15.4.0 (#430)
    • 



1.3.0


    

  • Recover from module errors on module level (#187)
    • 



1.2.9


    

  • Silently ignore exports that raise an error when accessed (#114)
    • 

  • Update source-map dependency
    • 



1.2.8


    

  • Remove React from peerDependencies
    • 

  • Update React Hot API to support React 0.14 beta 1
    • 



1.2.7


    

  • Preserve CommonJS exports context in the wrapping closure (#124)
    • 



1.2.6


    

  • Fix autobinding on newly added methods for createClass-style classes
    • 



1.2.5


    

  • Fix “React is not defined” error
    • 



1.2.4


    

  • Avoid updating each class twice in React 0.12
    • 



1.2.3


    

  • Explicitly exclude react/lib files from processing. You should use exclude: /node_modules/ in configuration, but at least this doesn't blow up for those who don't.
    • 



1.2.2


    

  • Fix crash on React 0.13. Now compatible!
    • 



1.2.1


    

  • Don't try to flatten inheritance chains, as it causes problems with super
    • 

  • Instead, automatically opt custom base classes into hot reloading as long as they descend from React.Component (in React 0.13). If your custom base class doesn't do that but you'd still want to have hot reloading, you need to manually opt it in via module.makeHot API.
    • 



1.2.0


    

  • Support hot-reloading components without a base class (react-hot-api#5)
    • 

  • Support hot-reloading inheritance chains (react-hot-api#10)
    • 

  • Support using React 0.13 as an external
    • 



1.1.7


    

  • Add React 0.13 RC2 to peerDeps
    • 



1.1.6


    

  • Allow React 0.13 RC1
    • 

  • Better support for ES6 inheritance
    • 

  • Fix reloading for modules with null prototype chain (#82)
    • 



1.1.5


    

  • Wrap user code in IEFF to prevent losing "use strict". Fixes #75
    • 



1.1.4


    

  • Fix crash when hot-reloading element factory. (Note: React discourages exporting factories.)
    • 



1.1.3


    

  • Avoid warnings on React 0.13
    • 



1.1.2


    

  • Compatibility with React 0.13.0-beta.1
    • 



1.1.1


    

  • Fix edge cases by requiring react/lib/ReactMount in transformed source files
    • 

  • Add a warning if ReactMount doesn't return anything useful (e.g. when using external React)
    • 



1.1.0


    

  • Skipping node_modules entirely wasn't the best idea. Instead, we now specifically skip node_modules/react/, node_modules/webpack/ and node_modules/react-hot-loader/. However you are still encouraged to add exclude: /node_modules/ to your loader config for best performance.
    • 

  • Now modules that don't export any valid React classes in module.exports or any its properties will not be auto-accepted. This prevents hot loader from trying to handle non-React updates and allows changes in plain JS files to propagate to components that can handle them. For example, this allows react-jss mixin to apply hot updates to JSS styles.
    • 



1.0.7


    

  • Skip node_modules entirely. Fixes #54 on Windows.
    • 



1.0.6


    

  • Add require('react-hot-loader/Injection') to override Hot Loader behavior. Now you can supply your own way of getting root component instances, so Hot Loader can also work in environment where require('react/lib/ReactMount') is not available (for example, when React is used as standalone bundle and not NPM package).
    • 



1.0.5


    

  • Fix stack overflow when hotifying same class twice (#52)
    • 



1.0.4


    

  • Allow both module.exports and its properties be components (Fixes #50)
    • 



1.0.3


    

  • In addition to hotifying module.exports by default, also hotify all its own properties
    • 



1.0.2


    

  • Don't try to hot-replace module.exported ReactElements
    • 



1.0.1


    

  • Delay requireing ReactMount to avoid circular dependencies
    • 

  • Don't process React or Webpack internals to avoid potential issues
    • 



1.0.0


    

  • Don't rely on createClass regex or any other regex
    • 

  • Only module.exports is hot by default
    • 

  • Supports ES6 classes when they land in React 0.13
    • 

  • Supports dynamically created classes
    • 

  • Manual mode
    •
