A simple wrapper for a simpler JWT surface API
npm install jwt-service[//]: # ( )
[//]: # (This file is automatically generated by a metapak)
[//]: # (module. Do not change it except between the)
[//]: # (content:start/end flags, your changes would)
[//]: # (be overridden.)
[//]: # ( )

[//]: # (::contents:start)
This wrapper is directly usable with
Knifecycle.
Let's say you wanna create a sub-service of this one with custom inputs, for
say, refresh tokens in a Whook project,
here is how you would do:
``ts
import initJWT, { JWTServiceConfig } from 'jwt_service';
import { inject } from 'knifecycle';
export type RefreshJWTServiceConfig = {
ENV: JWTServiceConfig['ENV'];
REFRESH_JWT_SECRET_ENV_NAME: JWTServiceConfig['JWT_SECRET_ENV_NAME'];
REFRESH_JWT: JWTServiceConfig['JWT'];
};
export default inject(
[
'?JWT_SECRET_ENV_NAME>REFRESH_JWT_SECRET_ENV_NAME',
'JWT>REFRESH_JWT',
'?ENV',
'?log',
'?time',
],
initJWT,
);
`
[//]: # (::contents:end)
Promise.<JWTService>Instantiate the JWT service
Promise.<JWTService>Kind: global function
Returns: Promise.<JWTService> - A promise of the jwt service
| Param | Type | Description |
| --- | --- | --- |
| services | Object | The services to inject |
| [services.JWT_SECRET_ENV_NAME] | function | The environment variable name in which to pick-up the JWT secret |
| [services.ENV] | Object | An environment object |
| services.JWT | function | The JWT service configuration object |
| [services.log] | function | A logging function |
| [services.time] | function | A function returning the current timestamp |
Example
`js
import initJWTService from 'jwt-service';
const jwt = await initJWTService({
JWT: {
secret: 'secret',
duration: '2d',
tolerance: '2h',
algorithms: ['HS256'],
},
log: console.log.bind(console),
time: Date.now.bind(Date),
});
const token = await jwt.sign({ my: 'payload' });
`
* JWTService
* [.sign(payload, [algorithm])](#JWTService.sign) ⇒ Promise.<JWTSignResult>
* [.verify([token])](#JWTService.verify) ⇒ Promise.<Object>
Kind: static method of JWTService
Returns: Promise.<JWTSignResult> - A promise to be resolved with the signed token.
| Param | Type | Description |
| --- | --- | --- |
| payload | Object | The payload to sign |
| [algorithm] | String | The signing algorithm |
Example
`js`
const token = await jwt.sign({ my: 'payload' });
Kind: static method of JWTService
Returns: Promise.<Object> - A promise to be resolved with the token payload.
| Param | Type | Description |
| --- | --- | --- |
| [token] | String | The token to decode |
Example
`js``
const payload = await jwt.verify('my.jwt.token');
