SyntaxError: Unexpected token import

[seangwright]

The error I see is for the first import statement in my require'd file that uses ES modules

node main.js

(function (exports, require, module, __filename, __dirname) { import * as cheerio from 'cheerio';

SyntaxError: Unexpected token import

/// main.js
require('@std/esm')(module, { cjs: true, esm: 'js' });
const build = require('./build');
build();

/// build.js
import * as cheerio from 'cheerio';
// ... some other stuff

export function doBuild() {
}

I must be using esm incorrectly?

My aim in using ES modules in node (and thus esm) is to either use tsc to produce ES module .js files from Typescript sources or us ts-node to run everything in memory.

Thanks!

Hi @sgwatgit!

require('@std/esm')(module, { cjs: true, esm: 'js' });

should be

require = require('@std/esm')(module, { cjs: true, esm: 'js' });

Hi @jdalton - first: THANK YOU for sharing this great tool.
I too was having issues setting up a small project to use this for my tests (using Tape). This post helped. May I suggest that you use this example in the docs? It was not obvious (until you pointed out here) that I needed to override require locally with what is returned by std/esm :)
