### Any ember components hot-reloading
Main Idea of this addon - ability to reload changed components without application reloading.
This addon is continuation of the project [ember-cli-hot-loader](https://github.com/adopted-ember-addons/ember-cli-hot-loader) and includes part of it's codebase.
* __ember-cli__ >= `2.15.1`
* __ember-source__ >= `2.16`
Many thanks to [Toran Billups / @toranb](https://github.com/toranb) for this huge work, support and inspiration!
* `ember-cli-hot-loader` implemented using middleware for `ember-resolver` and `wrapping` components.
* `ember-ast-hot-load` implemented using compile-time templates `ast` transformations.

Installation
------------------------------------------------------------------------------
```
ember install ember-ast-hot-load
```
* Ember.js v3.20 or above
* Ember CLI v3.20 or above
* Node.js v10 or above
## How to use this addon
It should just work without any config.
After the installing, simply run `ember serve` as you normally would. Any changes to component JS/HBS files will result in a hot reload (not a full page reload). If you alter a route, service, or controller ember-cli will do a full page reload.
Hot-reloading Ember [helpers](https://guides.emberjs.com/v3.10.0/templates/writing-helpers/) is not supported.
Because helpers look like components (in the AST) they will be unnecessarily wrapped, e.g. `helper` -> `dynamic component` -> `helper`
To prevent this from happening, you can exclude helpers from the hot-loader pipeline by specifying a list of helper names in the add-on config.
```js
// ember-cli-build.js
new EmberApp(defaults, {
'ember-ast-hot-load': {
helpers: ["foo-bar", "liquid-if", ... ],
enabled: true
}
});
```
If you don't specify `helpers` in the config the addon will continue to work, but with it will also wrap all your helpers (you can see this in the `ember-inspector` components tab, e.g. `helper "you-app-helper-name"`).
To get a list of all the helpers in your app that hot-reload might think are components, run this script in a debug console in your browner. You can then use this list to configure the add-on.
```js
var componentLikeHelpers = Object.keys(require.entries)
.filter(name=>(name.includes('/helpers/')|| name.includes('/helper')))
.filter(name=>!name.includes('/-')).map(name=>{
let path = name.split('/helpers/');
return path.pop();
}).filter(name=>!name.includes('/')).uniq();
console.log(JSON.stringify(componentLikeHelpers))
```
You should also exclude `ember-ast-hot-load` from production builds (to avoid unnecessary calculations)
```js
// ember-cli-build.js
const environment = EmberApp.env();
// ...
const addonsToIgnoreInProdBuilds = [
environment === 'production' ? 'ember-ast-hot-load' : null
].filter(name => name !== null);
new EmberApp(defaults, {
addons: {
blacklist: addonsToIgnoreInProdBuilds
}
});
```
### Public API?
```js
service('hot-loader')
```
```js
.registerWillHotReload(onHotReload)
```
```js
.unregisterWillHotReload(onHotReload)
```
```js
.registerWillLiveReload(onLiveReload)
```
```js
.unregisterWillLiveReload(onLiveReload)
```
```js
// we need to prevent full app refresh if we can hande changed file.
function onLiveReload(event) {
if (event.modulePath.includes('redusers')) {
event.cancel = true;
requirejs.unsee('some-module');
}
}
function onHotReload(path) {
if (path.includes('redusers')) {
// do some hot-reload magic,
// for example
requirejs.resolve('some-module')
}
}
```
## Known Compatibility Workarounds
#### Serving your Ember app from a different backend (e.g. Rails)
In most development environments, Ember applications are served directly from Ember's development server, e.g. http://localhost:4200.
If you are using a different way of service your Ember app, you may need to override the URL that we use to reload your changes.
```js
// config/enironment.js
if (environment === 'development') {
ENV['ember-ast-hot-load'] = {
baseUrl: 'http://app.mydomain.test:4200'
}
}
```
