    Module Express JWT

    @byu-oit-sdk/jwt-express

    Requirements:

    • Node.js 18+
    • npm v9+
    npm install @byu-oit-sdk/jwt-express
    

    This express plugin allows for verification and decoding of JWTs.

    Along with the options for the CreateJwt() function (see docs for jwt package), the following options can be passed in when registering the plugin with fastify.

    Option Type Default Description
    prefix string - Used to specify what route the middleware is registered with.
    transformer JwtPayloadTransformer<Payload, Transformer> - The function that you will use for manipulating the JWT you are authenticating.
    getJwt function - A function for getting the JWT from the request. By default, the JWT is pulled from the auth header.
    validate boolean - Boolean used to signify if we want to validate the jwt if true, or just decode it if false.
    TypeScript Coding Example
    import express from 'express'
    import request from 'supertest'
    import { verifyJwtPlugin } from '../src/express.js'
    import { Type } from '@sinclair/typebox'

    // set up express server
    const app = express()

    // use the transformer
    const transformer = (payload: { 'http://byu.edu/claims/client_preferred_first_name': string }): { preferred_first_name: string } => ({ preferred_first_name: payload['http://byu.edu/claims/client_preferred_first_name'] })
    try {
    app.use(verifyJwtPlugin({ schema: Type.Object({ }, { additionalProperties: true }), key: '', validate: false, transformer }))
    } catch (e) {
    console.log(e)
    }

    // define an endpoint
    app.get('/', (req, res) => {
    res.send(req.caller)
    })
    const server = app.listen(3000)

    const response = await request(server).get('/').set('Authorization', /* A valid token */).send({ })
    console.log(response)

    server.close()
