Is there a way to
Express app;babel or @std/esm ?once I am committed to app.js of Express, I can't find a way to get out of it.
This seems like something that should be already on the web, but all I can find is above options (transpiling, esm).
With node.js, you HAVE to tell it that your main file you are loading is an ESM module. There are a couple ways to do that. The simplest is to just give the main file a .mjs file extension.
// app.mjs
import express from 'express';
const app = express();
app.get("/", (req, res) => {
res.send("hello");
});
app.listen(80);
Then, start your program with:
node app.mjs
This works - I just ran it with node v14.4.0:. The others ways to do it are discussed in the link I previously gave you here. Per that documentation, there are three ways to specify you are loading an ESM module as the top-level module file:
Files ending in .mjs.
Files ending in .js when the nearest parent package.json file contains a top-level field "type" with a value of "module".
Strings passed in as an argument to --eval, or piped to node via STDIN, with the flag --input-type=module.
