Docs Readme Markdown File Auto-Generation ​

Stencil is able to auto-generate readme.md files in markdown. This opt-in feature will save the readme files as a sibling to the component within the same directory. This can help you to maintain consistently formatted documentation for your components which live right next to them and render in GitHub.

To auto-generate readme files, add the docs-readme output target to your stencil.config.ts like so:

import { Config } from "@stencil/core";

export const config: Config = {
  outputTargets: [{ type: "docs-readme" }],
};

Another option would be to use the --docs CLI flag, like so:

stencil build --docs

This will cause the Stencil compiler to perform a one-time generation of README files.

Adding Custom Markdown to Auto-Generated Files ​

Once you've generated a readme.md file you can customize it with your own markdown content. Simply add your own markdown above the comment that reads: <!-- Auto Generated Below -->.

Custom Footer ​

Removing or customizing the footer can be done by adding a footer property to the output target. This string is added to the generated Markdown files without modification, so you can use Markdown syntax in it for rich formatting.

import { Config } from "@stencil/core";

export const config: Config = {
  outputTargets: [
    {
      type: "docs-readme",
      footer: "*Built with love!*",
    },
  ],
};

Generating to a Directory ​

By default, a readme file will be generated in the same directory as the component is corresponds to. This behavior can be changed by setting the dir property on the output target configuration. Specifying a directory will create the structure {dir}/{component}/readme.md.

import { Config } from "@stencil/core";

export const config: Config = {
  outputTargets: [
    {
      type: "docs-readme",
      dir: "output",
    },
  ],
};

Strict Mode ​

Adding strict: true to the output target configuration will cause Stencil to output a warning whenever the project is built with missing documentation.

import { Config } from "@stencil/core";

export const config: Config = {
  outputTargets: [
    {
      type: "docs-readme",
      strict: true,
    },
  ],
};
