Change Log

0.0.0 => 0.1.0

• feat: JWT sign & verify

See CHANGELOG for detail.

Usage

See simple demo for more detail.

Install

npm i --save @iinfinity/jwt

Create

Create a default JWT instance.

const jwt = new JWT(); // same as `new JWT({ algorithm: 'HS512', key: String(Date.now()), urlsafe: false })`

Create a custom JWT instance with urlsafe:

const customJWT = new JWT({ algorithm: 'HS256', key: 'key', urlsafe: true });

Sign

Define header & payload first:

const header: Header = {
  alg: 'HS256',
  typ: 'JWT'
};

const payload: Payload = {
  username: 'user',
  password: 'pass'
};

Sign with payload & default header:

const token = jwt.sign(payload);

Sign with payload & header, you can set special algorithm in header:

const token256 = jwt.sign(payload, header);

Verify

Verify token & parse it:

const verified: JSONWebToken | undefined = jwt.verify(token); // if failed to verify, return undefined
const verified256: JSONWebToken | undefined = jwt.verify(token); // use header.alg as Algorithm

If failed to verify, it will return undefined.
