nodemon not restarting after typescript change

Question

My nodemon is not restarting after a typescript file change.

Currently I'm using the following to run and compile my changes:

"dev": "nodemon -e ts,json --exec \"npm run compile\"",
"compile": "tsc && node src/index.js"

it should detect ts changes and recompile however it's not.

It is running through a docker container linked with a volume, the code in volume should be watched.

docker-compose

version: '2'
services:
  api:
    build:
      context: ./api
    ports: ["5000:5000"]
    environment:
      - NODE_ENV=production 

the override:

version: '2'
services:
  api:
    command: yarn run dev
    volumes:
      - ./api/src:/usr/workspace/api/src      
    environment:      
      - NODE_ENV=dev   

The api has the following dockerfile

FROM node:latest

# Install yarn
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - \
  && echo "deb http://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list  && apt-get update && apt-get clean

# Set working dir and copy contents of our images to that dir  
RUN mkdir -p /usr/workspace/api && cd /usr/workspace/api

# install dependencies
COPY *.json /usr/workspace/api/
WORKDIR /usr/workspace/api

# npm install will check NODE_ENV if its production if will not install dev dependencies
RUN npm install --silent && npm install -g nodemon pm2 typescript --silent

# copy sources
COPY ./src ./src

# create env file with the port
ENV PORT 8100
EXPOSE $PORT

CMD ["pm2-docker", "src/process.json"]

as you can see, with the override i run the development environment instead of staging

i have tried turning the watch option to true in my tsconfig however then the code doesn't re run. when i change the nodemon options to watch js files as well it works, however it then constantly rebuilds because it detects js files change when it compiles.

any opinions?

I have fixed this issue by adding the -L switch to nodemon. this apparently uses the legacy watch which worked on the docker container

"dev": "nodemon -L -e ts,json --exec \"npm run compile\"",
