Bug Report

I've started a new Node.js project and followed the passport authentication tutorial until:
https://docs.nestjs.com/techniques/authentication#jwt-functionality

Current behavior

Expected behavior

Applications should start.

Environment

My jsconfig.json file (I'v changed to esnext as suggested by nestjs/passport#27:

{
  "compilerOptions": {
      "target": "esnext",
      "experimentalDecorators": true
  },
  "exclude": [
      "node_modules"
  ]
}

Nest version: 6.7.2

 
For Tooling issues:
- Node version: v12.6.0  
- Platform:  Mac 

Others:

I've also edited local.strategy.js, i've switched the super(); and this.authService = authService; lines as I was getting an error:
TypeError: Cannot set property 'authService' of undefined

local.strategy.js

import { Strategy } from 'passport-local';
import { PassportStrategy } from '@nestjs/passport';
import { Injectable, UnauthorizedException, Dependencies } from '@nestjs/common';
import { AuthService } from './auth.service';

@Injectable()
@Dependencies(AuthService)
export class LocalStrategy extends PassportStrategy(Strategy) {
  constructor(authService) {
    super();
    this.authService = authService;
  }

  async validate(username, password) {
    const user = await this.authService.validateUser(username, password);
    if (!user) {
      throw new UnauthorizedException();
    }
    return user;
  }
}

Hi, wanted to try the framework and the project does not run since its missing modules after npm install. I only cloned the repo and run both npm install and npm run start.

This version of code not working anymore. I have tried installing with npm install but it's not installing all the required packages. As a result it's not running using npm run start

I'm following the docs to try out nest and I've not jumped on the typescript bandwagon just yet, but I was under the impression that this repo would contain standard js code... Is this the right place to start for someone not using typescript? The files in src have .js extensions but the code is still typescript.

node: 8.10.0

when i run "npm run start:dev", the issue occure.

I am trying to run npm run start:dev and getting below error.

I am trying on
Node Version: v10.7.0
NPM version: 6.1.0

Steps to reproduces

• Create new project nest n -l js myproject
• Follow the steps described here: https://docs.nestjs.com/techniques/mongodb
• npm run start:dev

Then I get this error:

Support for the experimental syntax 'classProperties' isn't currently enabled
Add @babel/plugin-proposal-class-properties (https://git.io/vb4SL) to the 'plugins' section of your Babel config to enable transformation.

How to fix it

• npm install --save-dev @babel/plugin-proposal-class-properties
• Add ["@babel/plugin-proposal-class-properties"] in the plugins array in .babelrc

Hope this can help :)

How to use decorators like @Param in project with JavaScript？

I use nestjs/javascript-starter but I don't know to to build dist for run in production ?

Thank you

Hi there,

I cloned this repo and it looks like when I try to use nest-cli commands such as nest build or nest start I get this error

 Error  Could not find TypeScript configuration file "tsconfig.build.json". Please, ensure that you are running this command in the appropriate directory (inside Nest workspace).

This, I assume is because the default language when you nest start is TypeScript. Using npm start is fine, but I'm not too sure about using babel-node in a production environment since the babel-node docs explicitly say it's not meant for production.

Right now my work around is to transpile manually using babel-cli using something that looks like this npx babel src/ --out-dir dist/ and then I just node dist/main.js on the prod server.

My question is, am I missing something entirely about nest-cli usage? Or am I going about this in an acceptable way since the build should just be a transpilation anyways?

Thanks in advance

babel/babel#10221

I started this template repo.

but I can't use @Body decorator in parameter.

after 3hours, I researched that as drilling

I can find the issue with babel.

Plz add this package and code in .babelrc file for starter nestjs/JS
