Parse all `<img>` tags, during doc-gen, and insert the width and height of the sourceed image, if neither are already specified. Warnings are reported if the `<img>` tag has no `src` attribute or the image cannot be loaded. The work is done in the `addImageDimensions` post-processor, which must be configured with a `basePath` so that it knows where to find the images. Closes #15888
Documentation Generation
The dgeni tool is used to generate the documentation from the source files held in this repository.
The documentation generation is configured by a dgeni package defined in tools/transforms/angular.io-package/index.js.
This package, in turn requires a number of other packages, some are defined locally in the tools/transforms folder,
such as tools/transforms/cheatsheet-package and tools/transforms/content-package, etc. And some are brought in from the
dgeni-packages node modules, such as jsdoc and nunjucks.
Generating the docs
To generate the documentation simply run yarn docs from the command line.
Testing the dgeni packages
The local packages have unit tests that you can execute by running yarn docs-test from the command line.
What does it generate?
The output from dgeni is written to files in the src/content folder.
Notably this includes a JSON file containing the partial HTML for each "page" of the documentation, such as API pages and guides. It also includes JSON files that contain metadata about the documentation such as navigation data and keywords for building a search index.
Viewing the docs
You can view the pages by running yarn start and navigating to https://localhost:4200.
