eslint-plugin-jsdoc
Advanced tools
The eslint-plugin-jsdoc package is a plugin for ESLint that provides linting rules for JSDoc comments. JSDoc is a markup language used to annotate JavaScript source code files. Using eslint-plugin-jsdoc, developers can ensure that their JSDoc comments are consistent and follow best practices.
Check alignment
Ensures that JSDoc blocks are aligned properly.
/* eslint jsdoc/check-alignment: "error" */
/**
* Function description.
*
* @param {string} name - The name of the person.
* @return {string} - The greeting message.
*/
function greet(name) {
return `Hello, ${name}!`;
}Check indentation
Ensures that JSDoc blocks have consistent indentation.
/* eslint jsdoc/check-indentation: "error" */
/**
* Function description.
*
* @param {string} name - The name of the person.
* @return {string} - The greeting message.
*/
function greet(name) {
return `Hello, ${name}!`;
}Check types
Validates JSDoc comments for type correctness.
/* eslint jsdoc/check-types: "error" */
/**
* Function description.
*
* @param {String} name - The name of the person.
* @return {String} - The greeting message.
*/
function greet(name) {
return `Hello, ${name}!`;
}Require JSDoc
Requires JSDoc comments for certain nodes in the code.
/* eslint jsdoc/require-jsdoc: "error" */
/**
* Function description.
*/
function greet(name) {
return `Hello, ${name}!`;
}TSDoc is a documentation comment format used for TypeScript source files. It is similar to JSDoc but tailored for the TypeScript language, providing a standardized way to document TypeScript APIs. Unlike eslint-plugin-jsdoc, TSDoc does not provide linting rules but focuses on the comment format itself.
The 'documentation' package is a documentation generator that uses JSDoc comments to produce documentation for JavaScript code. It is similar to eslint-plugin-jsdoc in that it processes JSDoc comments, but its primary purpose is to generate documentation rather than lint code.
TypeDoc is a documentation generator for TypeScript projects. It reads TypeScript source files and JSDoc comments to produce documentation. While eslint-plugin-jsdoc focuses on linting JSDoc comments, TypeDoc uses them to generate documentation websites or markdown files.
JSDoc linting rules for ESLint.
This table maps the rules between eslint-plugin-jsdoc and jscs-jsdoc.
Install ESLint either locally or globally.
npm install eslint
If you have installed ESLint globally, you have to install JSDoc plugin globally too. Otherwise, install it locally.
npm install eslint-plugin-jsdoc
Add plugins section and specify eslint-plugin-jsdoc as a plugin.
{
"plugins": [
"jsdoc"
]
}
Finally, enable all of the rules that you would like to use.
{
"rules": {
"jsdoc/check-param-names": 1,
"jsdoc/check-tag-names": 1,
"jsdoc/check-types": 1,
"jsdoc/newline-after-description": 1,
"jsdoc/require-description-complete-sentence": 1,
"jsdoc/require-hyphen-before-description": 1,
"jsdoc/require-param": 1,
"jsdoc/require-param-description": 1,
"jsdoc/require-param-type": 1,
"jsdoc/require-returns-description": 1,
"jsdoc/require-returns-type": 1
}
}
check-param-namesEnsures that parameter names in JSDoc match those in the function declaration.

newline-after-descriptionEnforces a consistent padding of the block description.
This rule takes one argument. If it is "always" then a problem is raised when there is a newline after the description. If it is "never" then a problem is raised when there is no newline after the description. The default value is "always".
