Restart via 'rs', even without changes to watched files

[Tjomas]

• nodemon -v: 1.12.5
• node -v: v8.9.1
• Command you ran: nodemon --legacy-watch --on-change-only --verbose < $pipeNodemon &amp; pid=$!

Nodemon runs inside a docker container.
There are unwatched file extensions that another process creates. When all the files are completely written, i want to send a manual signal through a pipe. However, this has no effect, since the restart is not executed because no changes are detected.
A restart should be a restart no matter if there are any changes.

With or without "--on-change-only" makes no difference.

entrypoint.sh:
mkfifo $pipeNodemon
nodemon --legacy-watch --on-change-only --verbose < $pipeNodemon &amp; pid=$!

// At some point later
echo -e "rs\r\n" > $pipeNodemon

Config

{
"ext": "json hbs trigger",
"delay": "300",
"watch": [
"dist"
],
"exec": "node --inspect=0.0.0.0:9229 ./dist/server.js",
"ignore": [
"src/**/*.spec.ts"
]
}

Expected behaviour

A real restart.

Actual behaviour

A change detection without a restart.

backend-api_1 | [TSC] 13:48:52 - File change detected. Starting incremental compilation...
backend-api_1 | [TSC] 13:48:52 - Compilation complete. Watching for file changes.
backend-api_1 | [TSC] 13:48:52 - Trigger nodemon // this is the: echo -e "rs\r\n" > $pipeNodemon
backend-api_1 | [nodemon] files triggering change check: dist/modules/database/product/product.entity.js
backend-api_1 | [nodemon] matched rule: /app/dist//*
backend-api_1 | [nodemon] changes after filters (before/after): 1/0

Steps to reproduce

1. Remove .js from the watched extensions.
2. Touch some js file
3. Send rs

Thank you for any advice.

I'm pretty sluggish when it comes to working with Docker, so do you think you could pull together a simple script that you can run instead of nodemon that will echo out the stdin that you're intending to inject? That way we can rule out that node isn't the problem.

nodemon reads stdin like this:

      process.stdin.resume();
      process.stdin.setEncoding('utf8');
      process.stdin.on('data', function (data) {
        data = (data + '').trim().toLowerCase();
        console.log(data); // nodemon would _do_ something with data
      });

I'm not 100% sure you want to pipe to stdin, but with [email protected] you can send a SIGHUP to nodemon and it trigger a restart. I'm going to close as I believe this is a workaround that I think you're after. Happy to reopen if not.

Thank you. Works perfect!
