koa-jwt-login-example

This is a quick app to demonstrate how to use koa and koa-jwt to create a secure rest api.

This README assumes you're using yarn. If not, you can substitute npm commands where appropriate.

Setup

• clone the git repo:

git clone https://github.com/clintmod/koa-jwt-login-example.git

• run yarn to install the dependencies
• run yarn local to run node via nodemon to auto-reboot node if you edit source files

Running the tests

You can run the tests with the usual:

yarn test

If you want to develop more tests you can run:

yarn test-mocha-watch

This will start mocha in watch mode.

Testing the api

• use curl to register a new user:

curl -X POST --data '{"username":"thedude", "password":"abides", "email":"[email protected]", "name":"Mr. Lebowski"}' http://localhost:9000/public/register

• use curl to login with that user and get a token:

curl -X POST -H "Content-Type: application/json" --data '{"username":"thedude", "password":"abides"}' http://localhost:9000/public/login

• use curl to access the secured api/v1 route with the token you received in the login step

curl -X GET -H "Authorization: Bearer INSERT_TOKEN_HERE" http://localhost:9000/sacred

Notes

You'll notice in the package.json I'm using a forked version of koa-jwt. This is because currently, there's no "documented" way to know when a token expires. I've opened an issue and sent a pull request with what I think is an appropriate fix. When the pull request gets merged and released I'll update the demo with the new version of koa-jwt.

I also hash the password using bcrypt because you should always hash your passwords.
