HTTP Request Method Database

This is a database of known HTTP Request Methods and information about them. It consists of a single, public JSON file and does not include any logic, allowing it to remain as un-opinionated as possible with an API. It aggregates data from the following sources:

• https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods
• https://www.iana.org/assignments/http-methods/http-methods.xhtml

Installation

npm i --save http-request-method-db

Database Download

If you want download the database and use it directly in the browser, you can just grab the JSON file using jsDelivr. It is recommended to replace main with a release tag as the JSON format may change in the future.

https://cdn.jsdelivr.net/gh/pichillilorenzo/http-request-method-db@main/dist/db.json

Usage

import db from 'http-request-method-db';
// .. or
const db = require('http-request-method-db').default;

const getInfo = db['get']; // An instance of HTTPRequestMethod
console.log(getInfo.syntax); // GET /index.html

Access HTTP Request Method info using the request method name in lower case as key.

Contributing

The primary way to contribute to this database is by updating the data in one of the upstream sources. Check the scripts/src/mdn-scraper.ts to check the MDN scraper implementation.

Direct Inclusion

If that is not possible / feasible, they can be added directly here as a "custom" request method.

To edit the database, only make PRs against scripts/src/custom-request-methods.json.

The scripts/src/custom-request-methods.json file is a JSON object of type HTTPRequestMethodDb, where each key is the request method name in lower case and the value is an Object of type HTTPRequestMethod.

To update the build, run npm run build:all.

It is better to just avoid sending payloads in GET requests.",
