This metadoc post-processor will generate a static (read-only) JSON "API" for browsing metadoc data.

The output is structured in a simple folder that can be uploaded to a static web host. However; since there is no index.html file, it's important to configure your server to use index.json as the default file.

The file structure will always contain:

├─┬ global
│ ├── MyClassA.json
│ ├── MyClassB.json
│ └── …
├─┬ mynamespace
│ ├── MyClassC.json
│ ├── MyClassD.json
│ └── …
├── api.bus.json
├── api.classes.json
├── api.json
├── api.bus.json
├── api.namespaces.json
└── index.json

An example of the index.json (last file) may be:

  "full_spec_href": "https://domain.com/4.0.0/api.json",
  "bus_href": "https://domain.com/4.0.0/api.bus.json",
  "exceptions_href": "https://domain.com/4.0.0/api.exceptions.json",
  "class_href": "https://domain.com/4.0.0/api.classes.json",
  "namespace_href": "https://domain.com/4.0.0/api.namespaces.json"


Simply run metadoc-api as a command in the metadoc chain. For example:

metadoc --source ./src --output ./docs | metadoc-api

There are two optional flags: --root (web root) and --version (API version/subfolder).

metadoc --source ./src --output ./docs | metadoc-api --root https://domain.com/ --version 2.0.0

The example above will produce links prefixed with https://domain.com/2.0.0/.

--version auto can be used to automatically identify the version from a local package.json file. The source directory will be searched for a package.json file first, then the current working directory.

Testing Locally

Testing your API locally can be done with any static web host. We recommend using Fenix Web Server.

Fenix Web Server

Fenix will support static hosting and default file modification. Oh, and it's free.

Guiding Principles

This is a read-only/static API, but it attempts to follow reasonable API guidelines. For example, subresources are all identified with a href or _href attribute, allowing API clients to traverse the entire API programmatically.

The API aims to be as simple as possible, but documentation websites are often more complex than they appear. To facilitate the simplest development flow possible, a few helper files are generated and put in the API root:


This file acts like index.html would in a web server, i.e. the default page served when no other is specified. It contains links to the primary resources documented in the API.


This is a failsafe file. It contains all of the output from metadoc, in case you can't get the detail you need from anywhere else. WARNING: This file can be really, really big (10K+ lines). Use alternatives whenever possible.


Remember, metadoc was designed for NGN, which is an object oriented programming library focused around a core event emitter. The bus is an event bus. This file contains all of the events triggered by an event bus. If you're not using NGN, this file may or may not be of use to you.


This file contains a list of all available classes in the code being documented.


This file contains all of the global/customer exceptions triggered by the code being documented.


This file contains all of the namespaces recognized within the code being documented.
