Parser for outputting a Javascript object from documented code via JSDoc's explain (-X) command.

Install via NPM:

npm i jsdoc-x

Usage:

const jsdocx = require('jsdoc-x');
try {
    const docs = await jsdocx.parse('./src/**/*.js');
    console.log(docs);
} catch (err) {
    console.log(err.stack);
}

(If you like pain, .parse() method also supports a callback, instead of promises.)

See an output example here.

jsdocx.parse(options[, callback])

Executes the jsdoc -X command and parses the output into a Javascript object/array; with the specified options.

Param Type Description
options Object|Array|String Required. Either an options object or one or more source files to be processed. See details below.
callback Function Callback function to be executed in the following signature: `function (err, array) { ... }`. Omit this callback to return a `Promise`. Default: undefined

options

Object|Array|String - Parse options.

Option Type Description
files String|Array Required (if source is not set). One or more file/directory paths to be processed. This also accepts a Glob string or array of globs. e.g. ./src/**/*.js will produce an array of all .js files under ./src directory and sub-directories. Default: undefined
source String Required (if files is not set). Documented source code to be processed. If files is also set, this will be ignored. Default: undefined
config Object Pass a configuration object to the underlying JSDoc core. This will bypass all parser options. Default: {}
encoding String Encoding to be used when reading source files. Default: "utf8"
recurse Boolean Specifies whether to recurse into subdirectories when scanning for source files. Default: false
pedantic Boolean Specifies whether to treat errors as fatal errors, and treat warnings as errors. Default: false
access String|Array Specifies which symbols to be processed with the given access property. Possible values: "private", "protected", "public" or "all" (for all access levels). By default, all except private symbols are processed. Note that, if access is not set for a documented symbol, it will still be included, regardless of this option. Default: undefined
private Boolean Shorthand for enabling documentation for private access symbols. Default: false
package String The path to the package.json file that contains the project name, version, and other details. If set to true instead of a path string, the first package.json file found in the source paths. Default: undefined
module Boolean Specifies whether to include module.exports symbols. Default: true
undocumented Boolean Specifies whether to include undocumented symbols. Default: true
undescribed Boolean Specifies whether to include symbols without a description. Default: true
ignored Boolean Specifies whether to include symbols marked with @ignore tag. Default: true
allowUnknownTags Boolean Specifies whether to allow unrecognized tags. If set to false parsing will fail on unknown tags. Default: true
dictionaries Array Indicates the dictionaries to be used. By default, both standard JSDoc tags and Closure Compiler tags are enabled. Default: ["jsdoc", "closure"]
includePattern String String pattern for defining sources to be included. By default, only files ending in ".js", ".jsdoc", and ".jsx" will be processed. Default: ".+\\.js(doc|x)?$"
excludePattern String String pattern for defining sources to be ignored. By default, any file starting with an underscore or in a directory starting with an underscore will be ignored. Default: "(^|\\/|\\\\)_"
plugins Array Defines the JSDoc plugins to be used. See this guide on JSDoc plugins. Default: []
relativePath String When set, all symbol.meta.path values will be relative to this path. Default: undefined
predicate Function|string Alias: filter. This is used to filter the parsed documentation output array. If a Function is passed; it's invoked for each included symbol. e.g. function (symbol) { return symbol; } Returning a falsy value will remove the symbol from the output. Returning true will keep the original symbol. To keep the symbol and alter its contents, simply return an altered symbol object. If a RegExp string is passed, it's executed on the symbol's long name. Default: undefined
hierarchy Boolean Specifies whether to arrange symbols by their hierarchy. This will find and move symbols that have a memberof property to a $members property of their corresponding owners. Also the constructor symbol will be moved to a $constructor property of the ClassDeclaration symbol; if any. Default: false
sort Boolean|String Specifies whether to sort the documentation symbols. For alphabetic sort, set to true or "alphabetic". To group-sort set to "grouped". (Group sorting is done in the following order: by memberof, by scope, by access type, by kind, alphabetic.) To sort by only "scope" or "access" or "kind", set to corresponding string. (Sorting by kind is done in the following order: constant, package/module, namespace, class, constructor, method, property, enum, typedef, event, interface, mixin, external, other members.) Set to false to disable. Default: false
output String|Object Path for a JSON file to be created, containing the output documentation array. Or you can set this to an object for extra options. Default: undefined
output.path String Path for a JSON file to be created. Default: undefined
output.indent Boolean|Number Number of spaces for indentation. If set to true, 2 spaces will be used. Default: false
output.force Boolean Whether to create parent directories if they don't exist. Default: false
debug Boolean Specifies whether to include extra information within thrown error messages. Default: true

jsdocx.filter(docs[, options][, predicate])

Filters the given documentation output array. This is useful if you have an already parsed documentation output.

Param Type Description
docs Array Required. Documentation output array.
options Object Filter options. See details below. Default: undefined
predicate Function The function invoked per iteration. Returning a falsy value will remove the symbol from the output. Returning true will keep the original symbol. To keep the symbol and alter its contents, simply return an altered symbol object. Default: undefined

options

Object - Filter options.

Option Type Description
access String|Array Specifies which symbols to be processed with the given access property. Possible values: "private", "protected", "public" or "all" (for all access levels). By default, all except private symbols are processed. Note that, if access is not set for a documented symbol, it will still be included, regardless of this option. Default: undefined
package String The path to the package.json file that contains the project name, version, and other details. If set to true instead of a path string, the first package.json file found in the source paths. Default: undefined
module Boolean Specifies whether to include module.exports symbols. Default: true
undocumented Boolean Specifies whether to include undocumented symbols. Default: true
undescribed Boolean Specifies whether to include symbols without a description. Default: true
relativePath String When set, all symbol.meta.path values will be relative to this path. Default: undefined
hierarchy Boolean Specifies whether to arrange symbols by their hierarchy. This will find and move symbols that have a memberof property to a $members property of their corresponding owners. Also the constructor symbol will be moved to a $constructor property of the ClassDeclaration symbol; if any. Default: false
sort Boolean|String Specifies whether to sort the documentation symbols. For alphabetic sort, set to true or "alphabetic". To additionally group by scope (static/instance) set to "grouped". Set to false to disable. Default: false

jsdocx.utils
