I'm trying to convert my typescript files to javascript files on my github actions pipeline. I am using Node.js/Express.js with typescript.
Problem
The CI is stuck at step "install dependencies & convert typescript to javascript". It looks like it works since I can see the console.log() , but the CI will not finish. Why is that?
Here is my package.json:
npm run convert converts typescript to javascript files into the backend-build folder. The backend-build folder contains the js file after conversion. The backend-build folder is not tracked in the repository because they are compiled files from npm run convert (i.e an Artifact).
I run it whenever I start my server.

}
Here is my typescript file (index.ts):
import express from "express";
import dotenv from "dotenv";
import cors from "cors";
if (process.env.NODE_ENV !== "production") {
dotenv.config();
}
const app = express();
// middleware for parsing bodies from URL
app.use(express.urlencoded({ extended: true }));
app.use(express.json());
app.use(cors({ origin: true, credentials: true }));
console.log("NODE ENV", process.env.privateKey);
app.use("/api/test", (req, res) => {
res.send("hi");
});
const port = process.env.PORT || 5000;
app.listen(port, () => {
console.log(`App running on port ${port}.`);
});
Here is my main.yml for Github actions:

CodePudding user response：
The job is staying "open" because of the -w (watch) directive. You don't want to use watch on your CI jobs unless you're also doing something to kill the watched process.
The errors suggest that your paths aren't correct so it's trying to run tsc -w, and then failing to find anything in the given path (./gh_actions_heroku_backend/gh_actions_heroku_backend) and then staying "open" because of the watch directive.
