# Angular documentation project (https://angular.io)
|
|
|
|
Everything in this folder is part of the documentation project. This includes
|
|
|
|
* the web site for displaying the documentation
|
|
* the dgeni configuration for converting source files to rendered files that can be viewed in the web site.
|
|
* the tooling for setting up examples for development; and generating plunkers and zip files from the examples.
|
|
|
|
## Developer tasks
|
|
|
|
We use `yarn` to manage the dependencies and to run build tasks.
|
|
You should run all these tasks from the `angular/aio` folder.
|
|
Here are the most important tasks you might need to use:
|
|
|
|
* `yarn` - install all the dependencies.
|
|
* `yarn setup` - Install all the dependencies, boilerplate, plunkers, zips and runs dgeni on the docs.
|
|
|
|
* `yarn start` - run a development web server that watches the files; then builds the doc-viewer and reloads the page, as necessary.
|
|
* `yarn serve-and-sync` - run both the `docs-watch` and `start` in the same console.
|
|
* `yarn lint` - check that the doc-viewer code follows our style rules.
|
|
* `yarn test` - watch all the source files, for the doc-viewer, and run all the unit tests when any change.
|
|
* `yarn e2e` - run all the e2e tests for the doc-viewer.
|
|
|
|
* `yarn docs` - generate all the docs from the source files.
|
|
* `yarn docs-watch` - watch the Angular source and the docs files and run a short-circuited doc-gen for the docs that changed.
|
|
* `yarn docs-lint` - check that the doc gen code follows our style rules.
|
|
* `yarn docs-test` - run the unit tests for the doc generation code.
|
|
|
|
* `yarn boilerplate:add` - generate all the boilerplate code for the examples, so that they can be run locally. Add the option `-- --local` to use your local version of Angular contained in the "dist" folder.
|
|
* `yarn boilerplate:remove` - remove all the boilerplate code that was added via `yarn boilerplate:add`.
|
|
* `yarn generate-plunkers` - generate the plunker files that are used by the `live-example` tags in the docs.
|
|
* `yarn generate-zips` - generate the zip files from the examples. Zip available via the `live-example` tags in the docs.
|
|
|
|
* `yarn example-e2e` - run all e2e tests for examples
|
|
- `yarn example-e2e -- --setup` - force webdriver update & other setup, then run tests
|
|
- `yarn example-e2e -- --filter=foo` - limit e2e tests to those containing the word "foo"
|
|
- `yarn example-e2e -- --setup --local` - run e2e tests with the local version of Angular contained in the "dist" folder
|
|
|
|
* `yarn build-ie-polyfills` - generates a js file of polyfills that can be loaded in Internet Explorer.
|
|
|
|
## Using ServiceWorker locally
|
|
|
|
Since abb36e3cb, running `yarn start -- --prod` will no longer set up the ServiceWorker, which
|
|
would require manually running `yarn sw-manifest` and `yarn sw-copy` (something that is not possible
|
|
with webpack serving the files from memory).
|
|
|
|
If you want to test ServiceWorker locally, you can use `yarn build` and serve the files in `dist/`
|
|
with `yarn http-server -- dist -p 4200`.

## Guide to authoring
|
|
|
|
There are two types of content in the documentatation:
|
|
|
|
* **API docs**: descriptions of the modules, classes, interfaces, decorators, etc that make up the Angular platform.
|
|
API docs are generated directly from the source code.
|
|
The source code is contained in TypeScript files, located in the `angular/packages` folder.
|
|
Each API item may have a preceding comment, which contains JSDoc style tags and content.
|
|
The content is written in markdown.
|
|
|
|
* **Other content**: guides, tutorials, and other marketing material.
|
|
All other content is written using markdown in text files, located in the `angular/aio/content` folder.
|
|
More specifically, there are sub-folders that contain particular types of content: guides, tutorial and marketing.
|
|
|
|
We use the [dgeni](https://github.com/angular/dgeni) tool to convert these files into docs that can be viewed in the doc-viewer.
|
|
|
|
The [Authors Style Guide](https://angular.io/guide/docs-style-guide) prescribes guidelines for
|
|
writing guide pages, explains how to use the documentation classes and components, and how to markup sample source code to produce code snippets.
|
|
|
|
### Generating the complete docs
|
|
|
|
The main task for generating the docs is `yarn docs`. This will process all the source files (API and other),
|
|
extracting the documentation and generating JSON files that can be consumed by the doc-viewer.
|
|
|
|
### Partial doc generation for editors
|
|
|
|
Full doc generation can take up to one minute. That's too slow for efficient document creation and editing.
|
|
|
|
You can make small changes in a smart editor that displays formatted markdown:
|
|
>In VS Code, _Cmd-K, V_ opens markdown preview in side pane; _Cmd-B_ toggles left sidebar
|
|
|
|
You also want to see those changes displayed properly in the doc viewer
|
|
with a quick, edit/view cycle time.
|
|
|
|
For this purpose, use the `yarn docs-watch` task, which watches for changes to source files and only
|
|
re-processes the the files necessary to generate the docs that are related to the file that has changed.
|
|
Since this task takes shortcuts, it is much faster (often less than 1 second) but it won't produce full
|
|
fidelity content. For example, links to other docs and code examples may not render correctly. This is
|
|
most particularly noticed in links to other docs and in the embedded examples, which may not always render
|
|
correctly.
|
|
|
|
The general setup is as follows:
|
|
|
|
* Open a terminal, ensure the dependencies are installed; run an initial doc generation; then start the doc-viewer:
|
|
|
|
```bash
|
|
yarn
|
|
yarn docs
|
|
yarn start
|
|
```
|
|
|
|
* Open a second terminal and start watching the docs
|
|
|
|
```bash
|
|
yarn docs-watch
|
|
```
|
|
|
|
* Open a browser at https://localhost:4200/ and navigate to the document on which you want to work.
|
|
You can automatically open the browser by using `yarn start -- -o` in the first terminal.
|
|
|
|
* Make changes to the page's associated doc or example files. Every time a file is saved, the doc will
|
|
be regenerated, the app will rebuild and the page will reload.
