Question

The performance of the Express.js interface is currently lacking

Questions for using Express.js:

Code:

app.use(A)
app.use(B)


{
    const isCurlR = app.use(function (req, res, next) {
        next()
    })
    isCurlR.get('/getLatest', (req, res) => {})
}

{
    const isNotCurlR = app.use(function (req, res, next) {
        next()
    })
    isNotCurlR.get('/getLogs', (req, res) => {})
    isNotCurlR.get('/getCard', (req, res) => {})
}

Router workflow:

A → B → isCurlR → isNotCurlR → /getLatest

A → B → isCurlR → /getLogs

I want: A → B → isNotCurlR → /getLatest

When trying to access /cli, the isCurlR method works correctly,

However, when visiting /web, it first calls the isCurlR method,

But it should directly use the isNotCurlR method

I prefer not to complicate the interface path. Currently, I achieve this effect using the golang gin library.

typescript express go-gin

Answer №1

Why do you think about implementing the "isNotCurlR" concept in your code?

Here is my suggestion:

app.use((req, res, next) => {
  console.log('A');
  next();
});
app.use((req, res, next) => {
  console.log('B');
  next();
});

{
  const isNotCurlR = app.use(function (req, res, next) {
    console.log('isNotCurlR');
    next();
  });
  isCurlR.get('/getLatest', (req, res) => {
    res.send('ok');
  });
}

Edit

If you can provide more clarification on your issue, it would be helpful. Also, I recommend exploring Express Router as using the Express class may have limitations. You can refer to Router for more information.

Here's an example:

    //Protected
    let admin = express.Router()
    api.use("/admin", admin)
    admin.use((req, res, next) => {
        //Authentication
        try {
            const auth = req.headers.authorization
            if (!auth.includes("Bearer ")) {
                Index.unauthorized(res)
                return
            }
            const token = auth.split(" ")[1]
            req.token = jwt.verify(token, Index.Setting.SecretKey)
            next()
        }
        catch (e) {
            Index.unauthorized(res)
            return
        }
    })

    admin.get("/test", (req, res) => {
        res.json({ role: req.token.role })
    })

The route will be /api/admin/test. Any request that needs to pass through the admin section must undergo proper authentication.
