How to pass GitHub action event hook from a javascript to a bash file? - github

Question

I want to create a GitHub action that is simple and only run a bash-script file, see previous
question: How to execute a bash-script from a java script
With this javascript action, I want to pass values to the bash-script from the JSON payload given by GitHub.
Can this be done with something as simple as an exec command?
...
exec.exec(`export FILEPATH=${filepath}`)
...

I wanted to do something like this, but found there to be much more code needed that I originally expected. So while this is not simple, it does work and will block the action script while the bash script runs:
const core = require('#actions/core');
function run() {
try {
// This is just a thin wrapper around bash, and runs a file called "script.sh"
//
// TODO: Change this to run your script instead
//
const script = require('path').resolve(__dirname, 'script.sh');
var child = require('child_process').execFile(script);
child.stdout.on('data', (data) => {
console.log(data.toString());
});
child.on('close', (code) => {
console.log(`child process exited with code ${code}`);
process.exit(code);
});
}
catch (error) {
core.setFailed(error.message);
}
}
run()
Much of the complication is handling output and error conditions.
You can see my debugger-action repo for an example.
