dochammer v1.1.0

dochammer

Code documentation made easy and fun.

Motivation

Most of the projects uses the documentation in a different place (wiki, a readme, etc) and all the docs are centralized there.

The problem with this approach is because some times the members could forgot to update the doc because it's not directly visible.

The dochammer was created to have the markdown documentation side-by-side with your code without changing your code file (like jsdocs, etc).

Setup

Install dochammer:

npm install -g dochammer

In your project, create a dochammer.config.js on the root (same level as node_modules).

module.exports = {
  outputDir: './docs',
  inputDir: './my-app-src',
  inputFileExt: '.doc.md'
}

Usage

The dochammer has 2 types of documents you can create: page and component.

Page

A page is a document that will be generated. To explain better, let's use this sample:

You have a service in your application that returns a user by it's id:

+ services/
  + user/
    - get-user.service.js

module.exports = async id => {
  // ...
  return {
    // user data
  }
}

You can create a doc file for the service:

+ services/
  + user/
    - get-user.service.js
    - get-user.service.doc.md

---
type: page
filename: services
---

## Get User Service

This service returns a user by it's id.

### Usage:

const service = require('./get-user.service')
const user = await service('user-id-1')

Where:

Ok, we are done with our page.

Now, in the terminal in the root of your project, just run:

dochammer

It will generate a folder named docs (that we configured in the dochammer.config.js as outputFolder) with a file services.md (that was the filename in the doc header)

+ docs/
  - services.md

Component

Components are the best way to reuse documentation inside other documents.

To create a component, you just need to create a doc with:

---
type: component
id: my-component
---

## My component

bla bla bla

You can use it in your pages using:

---
type: page
filename: services
---

## My service

%{component:my-component}

Where my-component is the id of your component.

Now, if you run dochammer to generate the docs, the %{component:my-component} will be replaced with the content of the component doc.

component

---
type: component
id: my-component
---

## My component

bla bla bla

page

---
type: page
filename: services
---

## My service

%{component:my-component}

result

---
type: page
filename: services
---

## My service

## My component

bla bla bla

Using variables

You can use pre-configured variables in your template rendering.

To use it, you need to:

Add the variables to dochammer.config.js

// dochammer.config.js
module.exports = {
  variables: {
    api_url: 'http://api.com'
  },
  //...
}

Use the variable inside your doc

---
type: component
id: my-component
---

Hey this is a component

%{variable:api_url}

Including a table of contents in pages

Each generated page file can have an index guide if you want.

To add the table of contents index, just add includeTableOfContent to your config file:

// dochammer.config.js
module.exports = {
  includeTableOfContent: true,
  //...
}
