Migrate job from GitHub Actions to Worker

GitHub is going to start charging users for runtime in a few months. Since I'm already using workers for most of my stuff, I figured it'd be a good time to see if I can migrate to using it instead. Essentially what this job does is just run a js file (

node /src/api/register.js

node /src/api/register.js

node /src/api/register.js

node /src/api/register.js) whenever a specific file is updated (no need to run every time, only if there's any actual changes to registered information).

In my particular case, this file:
1. Loads another js file used by Worker (data to register).
2. Gets secrets from env.
3. Makes an API call with said data/secret.
4. Does this again with a second secret/endpoint (same data).

Since I'd be combining the two, it'd make sense to add another step that if this fails, the deploy halts and stays on the last good version (not sure if this is standard already or not).

What would be the best way to set this up on Workers? I'm obviously expecting to need to change some variable references and such, but want to make sure I'm doing this correct and clean. I'd like to keep it within the same worker and using its own separate file (

/src/api/register.js

/src/api/register.js

/src/api/register.js

/src/api/register.js), rather than depend on the main

/src/api/server.js

/src/api/server.js

/src/api/server.js

/src/api/server.js that serves everything else.

whenever a specific file is updated

By this you mean a specific file in the repo?

Yes. Basically if any one of three files are changed, it should run as there may be updated data. Otherwise, not needed.

Check if you can use the push event webhook in Github to invoke the Worker, check if the files in question have been changed then execute the remaning logic

Was kind of hoping for a way to just run it on the backend instead of exposing, even if restricted. Didn't want to rope it into everything else too much and keep it mostly isolated outside of the one file for the data.

If you already have Workers CI/CD setup running on all commits, you could just have a tiny script it runs first in the build that checks the files changed and then either does the logic or pokes your worker to do the logic, if I understand you. Otherwise Olaf's idea to stay external

Hmm, interesting. Good to know so I can procrastinate that lol. That's what I'm basically looking to do though. Run a script after build if files changed. It just loads a JSON from a js file, strings it up, makes two fetch calls.

The detailed version is it's updating the registered slash commands on my bot with Discord and Top.gg. If I don't update the commands file then it should re-register them. The other files are likely not needed, just the one. Honestly don't recall why I had the couple of others added.

If you didn't have Workers CI/CD setup yet, it supports Build Watch paths so you could have filtered it, but if you're already using it/wanting it to run on all commits, just going to have to filter in the build env. Probably easiest to do it in there, since you have all your files/full node and tools to adapt your existing script, and you can just return an error to stop the deployment if it fails

I'm not sure if I do or not. Maybe? I'm still finding more out about it all. Right now it's just GitHub linked to a worker so whenever I push to the repo, the worker pulls and starts the build as well as GitHub running the action job.
