Nestjs live reload not working with Docker

I am using Nestjs Mono repo and I am trying to live reload with docker-compose.

Here is my Dockerfile

FROM node:16

ENV NODE_ENV=development
WORKDIR /app

COPY package.json ./

RUN npm install

COPY . .

And this is my service in docker-compose.yml

auth:
    build:
      context: ./
      dockerfile: ./apps/auth/Dockerfile.dev
    volumes:
      - ./apps:/app/apps
    command: npm start

Here is the start command

nest start --watch

Service is working but it is not reloading on changes

Live reloading works properly on my local machine and in container if I don't use volume.

Nestjs version: 8.1.5

Update:

I have opened an issue of nestjs/cli

For future references: Hot reload error.

When you're using the NestJS CLI to start your application in watch mode it is done by calling tsc --watch, and as of version 4.9 of TypeScript, a new strategy for detecting file changes is used which is likely to be the cause of this problem. In order to fix this problem, you need to add a setting to your tsconfig.json file after the "compilerOptions" option as follows:

"watchOptions": {
    "watchFile": "fixedPollingInterval"
}

It's late but can help others. you can add options to NestJS webpack's config

look at this reference about to config it: https://docs.nestjs.com/recipes/hot-reload

and when you did, add this options (your config file has to be like this):

module.exports = function (options) {
    options.watchOptions = {
        poll: 1000,
        aggregateTimeout: 300,
    }

    return options
};

you don't need to install dependencies that were told in the document (those are just for example). only install webpack as --save-dev

This may me a bit late, I had the same issue and i have tried all the available solutions and the only one that worked for me that was mentioned by @jbool24 at https://stackoverflow.com/a/73476289/4910054

solution is to start the nest with --tsc :

"start:dev": "nest start --tsc --watch"
