Question posted in 
I am trying to run a typescript express.js in a docker container. After running the docker I get the following error:
> ts-node-dev src/app.ts
Using ts-node version 8.10.1, typescript version 3.9.2
TypeError [ERR_FEATURE_UNAVAILABLE_ON_PLATFORM]: The feature watch recursively is unavailable on the current platform, which is being used to run Node.js
at Object.watch (fs.js:1441:11)
at add (/app/node_modules/filewatcher/index.js:74:34)
at /app/node_modules/filewatcher/index.js:93:5
at FSReqCallback.oncomplete (fs.js:176:5)
my Dockerfile:
FROM node:alpine
WORKDIR /app
COPY package.json .
RUN npm install
COPY . .
CMD ["npm","start"]
and the package.json file:
{
"name": "app-name",
"version": "1.0.0",
"description": "Init master",
"main": "src/app.ts",
"scripts": {
"build": "./node_modules/.bin/tsc",

},

}
P.S. I have decided to include the fix:
change the Dockerfile:
FROM node:lts-alpine
and change the package.json:
"start": "ts-node-dev src/app.ts --poll"

Node v14 introduced a breaking change to the
fs.watch()API, specifically that therecursiveoption (which has never been supported on Linux) now raises theERR_FEATURE_UNAVAILABLE_ON_PLATFORMerror if used on Linux.A bug report and fix have been submitted to
filewatcher: https://github.com/fgnass/filewatcher/pull/6Until that fix is merged and a new version released, you’ll need to stick to NodeJS < v14, or override the
filewatcherpackage installed locally to include that patch.It seems this error caused by
node.jsv14, to fix it use this command:ts-node-dev --poll src/app.tsOr you can use another version of
node.jsrather than version 14
