Glimmer compiles Handlebars templates into document fragments rather than string buffers
Glimmer is a flexible, low-level rendering pipeline for building a "live" DOM from Handlebars templates that can subsequently be updated cheaply when data changes.
It is written in TypeScript.
The project is still going through rapid changes at the moment. For the time being, please refer the architecture overview for more information.
npm install
or yarn install
to ensure the required dependencies are installed.npm run build
to build each Glimmer package. The builds will be placed in the dist/
directory.Glimmer's packages are only built when running npm run build
(or ember build --env production
).
If you run ember build
without setting the production environment, dist/
will only contain test assets.
If you want to use the built packages in other projects, you can use npm run yarn:link
to execute the yarn link
command inside each built package. (You
must build the packages first with npm run build
).
ember test --server
Ember CLI is a CI tool, so it will run tests as you change files.
npm test
.npm start
.In TypeScript, private
and protected
refer to the class itself
(and its subclasses).
Sometimes, you want to add a property or method that shouldn't be considered part of the external API (for other packages or Ember) but is expected to be used as part of an internal protocol.
In that case, it's ok to mark the property as private
or
protected
and use ['property']
syntax to access the property
inside of the same package.
class Layout {
private template: Template;
}
function compile(layout: Layout, environment: Environment): CompiledBlock {
return layout['template'].compile(environment);
}
The idea is that the compile
function might as well be a private method
on the class, but because the function leaks into untyped code, we want
to be more careful and avoid exporting it.
Other use-cases might include protocols where a cluster of classes is intended to work together internally, but it's difficult to describe as a single class hierarchy.
This is a semi-blessed workflow according to the TypeScript team, and Visual Studio Code (and tsc) correctly type check uses of indexed properties, and provide autocompletion, etc.
You should not treat use of ['foo']
syntax as license to access
private properties outside of the package.
