elm-doc-preview

This is an Elm 0.19 offline documentation previewer for packages, applications, their dependencies and all cached packages.

It aims at rendering documentation exactly like the official package website to avoid any surprise when releasing a package.

“name”

It should use the same author/project format than packages, but the repository does not have to exist on GitHub.

The default name is my/application.

“summary”

A short summary for the application in less than 80 characters.

The default summary is “Elm application”.

“version”

A version using MAJOR.MINOR.PATCH format.

The default version is “1.0.0”.

“exposed-modules”

The modules to include in the documentation. All exposed symbols inside these modules must be documented or the documentation build will fail.

Port modules will be shown as normal modules.

Exposed modules contain by default those found in forked and local packages (see next section). Setting the field does not remove those modules from the list.

Forked and local packages in applications

elm-doc-preview will automatically exposes documentation for forked or local packages modules if their are exposed in an elm.json file located in the directory above the one declared in source-directories.

Typically, to import a forked package and keep its documentation, just clone it in the application directory, and add the forked packages src sub-directory in elm.json source-directories.

API

const DocServer = require('elm-doc-preview');
const server = new DocServer();
server.listen();

or with custom options:

const DocServer = require('elm-doc-preview');

// constructor(options) {
//   const {
//     debug = false,
//     dir = ".",
//     port = 8000,
//     browser = true,
//     reload = true
//   } = options || {};
//   ...
const server = new DocServer({ port: 9000, browser: false });

server.listen();

FAQ

Is elm-doc-preview secure enough to publicly host documentation?

elm-doc-preview is a development tool and is not designed to be exposed on internet. As such, no effort at all has been made to secure it and it most likely contains severe vulnerabilities. If you want to publicly share some documentation, use the online version or maybe host static web pages of the documentation (see below).

Why adding elm-application.json instead of using elm.json?

Extending elm.json would not be convenient because elm install will remove any unexpected field from it when run, and all the additional fields used by elm-doc-preview are currently unexpected for an application, even if they are valid for a package.

Why my forked/local/vendored packages modules are not automatically documented?

They are automatically added in the documentation if you kept the package elm.json file in the directory above the package src one.
