Create automatic documentation of your NodeJS API endpoints
npm install dictum.jsCreate automatic documentation of your NodeJS API endpoints.
#### NPM
``bash`
$ npm install --save-dev dictum.js
#### Yarn
`bash`
$ yarn add --dev dictum.js
The first step is to create a file in which we'll document our endpoints. So let's do that in documentation.js:
`node
var dictum = require('dictum.js');
// For every endpoints
dictum.document({
description: 'Some description for the given endpoint',
endpoint: '/some/endpoint',
method: 'GET',
requestHeaders: { / headers for endpoint / },
requestPathParams: { / path params for endpoint / },
requestBodyParams: { / body params for endpoint / },
responseStatus: 200,
responseHeaders: { / headers for response / },
responseBody: { / body params for response / },
resource: 'My Resource'
});
`
Second and last step, execute the created file to generate our html documentation in ./docs/index.html like the following:
`bash`
$ node documentation.js
If you pay attention to the basic usage, you will notice that it is a lot of boilerplate if your API has a lot of endpoints, this is not DRY. Luckily you can omit most of it when testing with chai:
`node
const chai = require('chai'),
dictum = require('dictum.js'),
server = require('./../app'),
should = chai.should();
describe('/some/endpoint GET', () => {
it('should fail login because of invalid username', () => {
chai.request(server)
.post('/some/endpoint')
.then((res) => {
res.should.have.status(200);
res.should.be.json;
dictum.chai(res, 'description for endpoint');
});
});
});
`
See the important line here:
`node`
dictum.chai(res, 'description for endpoint');
Using chai returned res object will supply all the information we need to address the given endpoint. Optionally, we can provide a second parameter containing a description for it.
Then, documentation will be created when running our tests.
#### Markdown syntax instead of HTML? Change the formatter:
`node`
dictum.setFormatter('markdown'); // default: 'html'
#### Publishing docs when using Express? Add:
`node
var express = require('express'),
path = require('path'),
app = express();
app.use('/docs', express.static(path.join(__dirname, 'docs')));
