N/A I think you're wrong Brody about prestart.

I created a file watcher for laravel log file and console log by default to see if it works.

 const logsDir = path.join(srcdir, 'storage', 'logs');
    (async () => {
        try {
            const watcher = fs.watch(logsDir);
            for await (const event of watcher) {
                if (event.eventType !== 'change' || !event.filename.endsWith('.log'))
                    continue;

                const logFile = await fs.readFile(path.join(logsDir, event.filename), 'utf-8');
                const regex = /^\[(?<date>.*)\]\s(?<env>\w+)\.(?<type>\w+):(?<message>.*)/gm;

                for (const match of logFile.matchAll(regex)) {
                    const { date, env, type, message } = match.groups;
                    console.log(`[${date}] ${env}.${type}: ${message}`)
                }
            }
        } catch (e) {
            console.error(e);
        }
    })();

 const logsDir = path.join(srcdir, 'storage', 'logs');
    (async () => {
        try {
            const watcher = fs.watch(logsDir);
            for await (const event of watcher) {
                if (event.eventType !== 'change' || !event.filename.endsWith('.log'))
                    continue;

                const logFile = await fs.readFile(path.join(logsDir, event.filename), 'utf-8');
                const regex = /^\[(?<date>.*)\]\s(?<env>\w+)\.(?<type>\w+):(?<message>.*)/gm;

                for (const match of logFile.matchAll(regex)) {
                    const { date, env, type, message } = match.groups;
                    console.log(`[${date}] ${env}.${type}: ${message}`)
                }
            }
        } catch (e) {
            console.error(e);
        }
    })();

@aleks - who wrote prestart.mjs, please confirm that on its own, it has nothing to do with file watching that is JavaScript, besides that, I don't see how any of this relates to prestart.mjs in any way shape or form may I know why it's not feasible to set laravel to log to stdout / stderr (I've seen it done before) but it is feasible to write something like that?

root•10mo ago

Prestart does absolutely nothing with file watching, it just writes some config files and fixes permissions I've been considering writing functionality to have it pull log files into stdout, though

Brody•10mo ago

okay so is there some difficulties to having Laravel send logs to stdout / stderr?

root•10mo ago

I don't know, I've never tried

Brody•10mo ago

I can't imagine it being more than a few changes

ScaiOP•10mo ago

From what I saw with the code sent here, it's working fine. The image is the code output, which is fired in prestart. I mean, to hook a function on prestart what is the file watching the logs

root•10mo ago

No, prestart exits when your app starts. I might be able to implement something like this, though - what's your idea? Maybe some ESM modules that are loaded asynchronously in, say, a .nixpacks/hooks directory?

ScaiOP•10mo ago

Then, why in local development isn't exiting?

ScaiOP•10mo ago

I mean, we can't add start hook on StartPhase, a ESM module like you said?

Brody•10mo ago

1. because now the code you wrote doesn't exit 2. because there's a single & nothing your doing has anything to do with prestart.mjs the way you think it does, you are simply just running a node script along side the php app

ScaiOP•10mo ago

Hmm, okay. I understand now. I don't have experience in Rust, just trying to understand from other languages knowledge the logic and making tests to see what is working and what is not.

root•10mo ago

What that code does is it runs the prestart script and then (after the script has exited) runs php-fpm and nginx in parallel.

Brody•10mo ago

& is not a good way to do that, I know that much

root•10mo ago

What would you suggest?

Brody•10mo ago

parallel or multirun

root•10mo ago

are those npm packages?

ScaiOP•10mo ago

Wouldn't running a nodejs alongside php-fpm and nginx cause a memory increase on server? ~40MB, because of the NodeJS runtime

Brody•10mo ago

as aleks has stated, prestart.mjs exits what you're doing doesn't exist, so yes what you're doing will add memory usage to the service

root•10mo ago

(the logical continuation of that statement was "if they are, then I have moral objections")

Brody•10mo ago

they are most certainly not

root•10mo ago

good, what are they and how are they better than & oh multirun does look cool

Brody•10mo ago

they both can run two (or more) commands in parallel, and they will exit all commands entirely if one command exits thus allowing railway to restart the container, unlike & where it sends the command to the background where it can die and stay dead
