@fubhy/docgen NPM

An opinionated documentation generator for Effect projects.

Credits

This library was inspired by the following projects:

docs-ts

Setup

Install @effect/docgen as a dev dependency:

pnpm add @effect/docgen -D

(Optional) Add a docgen.json configuration file.

{
  "$schema": "node_modules/@effect/docgen/schema.json"
}

Add the following script to your package.json file:

{
  "scripts": {
    "docs": "docgen"
  }
}

Warning To use "@effect/docgen", Node.js v18 or above is required.

Example Configuration

The docgen.json configuration file allows you to customize docgen's behavior. Here's an example configuration:

{
  "exclude": ["src/internal/**/*.ts"],
  "theme": "mikearnaldi/just-the-docs",
  "parseCompilerOptions": {
    "strict": true,
    "noEmit": true,
    "target": "ES2021",
    "lib": ["ES2021"],
    "paths": {
      "@effect/<project-name>": ["./src/index.ts"],
      "@effect/<project-name>/test/*": ["./test/*"],
      "@effect/<project-name>/examples/*": ["./examples/*"],
      "@effect/<project-name>/*": ["./src/*"]
    }
  },
  "examplesCompilerOptions": {
    "strict": true,
    "noEmit": true,
    "target": "ES2021",
    "lib": ["ES2021"],
    "paths": {
      "@effect/<project-name>": ["../../src/index.ts"],
      "@effect/<project-name>/test/*": ["../../test/*"],
      "@effect/<project-name>/examples/*": ["../../examples/*"],
      "@effect/<project-name>/*": ["../../src/*"]
    }
  }
}

Supported JSDoc Tags

Tag	Description	Default
`@category`	Groups associated module exports together in the generated documentation.	`'utils'`
`@example`	Allows usage examples to be provided for your source code. All examples are type checked using `ts-node`. Examples are also run using `ts-node` and the NodeJS assert module can be used for on-the-fly testing.
`@since`	Allows for documenting most recent library version in which a given piece of source code was updated.
`@deprecated`	Marks source code as deprecated, which will ~~strikethrough~~ the name of the annotated module or function in the generated documentation.	`false`
`@internal`	Prevents `docgen` from generating documentation for the annotated block of code. Additionally, if the `stripInternal` flag is set to `true` in `tsconfig.json`, TypeScript will not emit declarations for the annotated code.
`@ignore`	Prevents `docgen` from generating documentation for the annotated block of code.

By default, docgen will search for files in the src directory and will output generated files into a docs directory. For information on how to configure docgen, see the Configuration section below.

Configuration

docgen is meant to be a zero-configuration command-line tool by default. However, there are several configuration settings that can be specified for docgen. To customize the configuration of docgen, create a docgen.json file in the root directory of your project and indicate the custom configuration parameters that the tool should use when generating documentation.

The docgen.json configuration file adheres to the following interface:

interface Config {
  readonly projectHomepage?: string;
  readonly srcDir?: string;
  readonly outDir?: string;
  readonly theme?: string;
  readonly enableSearch?: boolean;
  readonly enforceDescriptions?: boolean;
  readonly enforceExamples?: boolean;
  readonly enforceVersion?: boolean;
  readonly exclude?: ReadonlyArray<string>;
  readonly parseCompilerOptions?: string | Record<string, unknown>;
  readonly examplesCompilerOptions?: string | Record<string, unknown>;
}

The following table describes each configuration parameter, its purpose, and its default value.

Parameter	Description	Default Value
projectHomepage	Will link to the project homepage from the Auxiliary Links of the generated documentation.	`homepage` in `package.json`
srcDir	The directory in which `docgen` will search for TypeScript files to parse.	`'src'`
outDir	The directory to which `docgen` will generate its output markdown documents.	`'docs'`
theme	The theme that `docgen` will specify should be used for GitHub Docs in the generated `_config.yml` file.	`'mikearnaldi/just-the-docs'`
enableSearch	Whether or search should be enabled for GitHub Docs in the generated `_config.yml` file.	`true`
enforceDescriptions	Whether or not descriptions for each module export should be required.	`false`
enforceExamples	Whether or not `@example` tags for each module export should be required. (Note: examples will not be enforced in module documentation)	`false`
enforceVersion	Whether or not `@since` tags for each module export should be required.	`true`
exclude	An array of glob strings specifying files that should be excluded from the documentation.	`[]`
parseCompilerOptions	tsconfig for parsing options (or path to a tsconfig)	{}
examplesCompilerOptions	tsconfig for the examples options (or path to a tsconfig)	{}

FAQ

Q: For functions that have overloaded definitions, is it possible to document each overload separately?

A: No, docgen will use the documentation provided for the first overload of a function in its generated output.
