Nest: Route params decorators bug in ES

[cdiaz]

Route params decorators not working properly in ES

I'm trying to use @Body decorator, but I'm getting unwanted results:

  @Post('/signup')
  async signUp (
    @Request() req, 
    @Response() res,
    @Body('username') username,
    @Body('password') password ) {
      console.log(username) //[Function: next] 
      console.log(password) //undefined
    }

Then I tried to send the @Body decorator arguments first, but when printing them I got equivalents to the Request, Response and Next in their respective order.

  @Post('/signup')
  async signUp (
    @Body('username') username,
    @Body('password') password,
    @Request() req, 
    @Response() res
  ) {
      console.log(username) //IncomingMessage {.........  <- req equivalent
      console.log(password) //ServerResponse {...... <- res equivalent
      console.log(req) //[Function: next]  <- next equivalent
      console.log(res) //undefined
    }

I think the problem is with the order or obligation of the params

I am experiencing this as well.

@kamilmysliwiec any known bugs here or workarounds?

Hi @benbayard, @cdiaz,

Unfortunately, babel doesn't support custom parameters decorators.. This is why it's not working without TypeScript :disappointed:

[benbayard]

I don't think I'm using babel though. I'm just using ts-node. Could I have something incorrect in my tsconfig?

[kamilmysliwiec]

@benbayard, it should work fine with ts-node. Could you share us your entire controller as an example?

[benbayard]

@kamilmysliwiec I was actually just able to solve the issue I was having by using target: es6 @cdiaz can you check if this works for you?

[cdiaz]

@benbayard Apparently you are using TypeScript, in my case I am using Babel, like this:
https://github.com/kamilmysliwiec/nest-babel-starter.
Therefore tsconfig does not apply in this case

[cojack]

@cdiaz show your babel config

[cdiaz]

@cojack This same

[cojack]

@cdiaz why you close the issue? it's fixed, did you found solution?

[kamilmysliwiec]

@cojack, i'm afraid there's no solution. The params decorators are the TypeScript feature.

Hey guys !
Did you try this ?
https://www.npmjs.com/package/babel-plugin-transform-function-parameter-decorators

I'll try this soon if no one do ;-)

[kamilmysliwiec]

@ThomRick the implementation is different, it won't work :disappointed:

[kamilmysliwiec]

Hi @cdiaz,
Now Nest is compatible with pure JavaScript + Babel now :slightly_smiling_face: You can find examples in the docs.

[mathis-m]

n find examples in the docs.
Could you provide a link to the examples?
