SyntaxError: Unexpected identifier with mocha and babel - javascript

I have a mocha test file (test/test.js) that starts like this, using ES6 module syntax:
import {promises as fs} from 'fs'
import stepToD3 from '../src/StepToD3'
import assert from "assert"
In addition, I have a babel.config.js file in the root of my project:
module.exports = {
presets: [
"#vue/app",
"#babel/preset-env"
]
}
I then want to test this using Mocha, transpiled through babel. I do so using mocha --require #babel/register test/test.js. However, somewhere during the execution, this fails with the following error:
/home/michael/Programming/cola-step/node_modules/#babel/runtime-corejs2/helpers/esm/asyncToGenerator.js:1
(function (exports, require, module, __filename, __dirname) { import _Promise from "../../core-js/promise";

Why is this failing to understand the ES6 import syntax if I'm using Babel? What is going wrong here?


In this case, I was running my tests with mocha on NodeJS, but my babel.config.js was set up to produce code for the browser. To fix this, I had to create two different babel settings, and then export the right NODE_ENV value before running the appropriate command (e.g. NODE_ENV=test mocha --require #babel/register for tests, and NODE_ENV=production for my webpack production build).
This is my new babel.config.js:
module.exports = {
'env': {
'production': {
'presets': [
[
'#vue/app',
{
// "modules": false,
'targets': ['ie >= 9']
},
'#babel/env'
]
],
'comments': false
},
'test': {
'presets': [
[
'#babel/env',
{'targets': {'node': 'current'}}
]
]
}
}
}

Typescript module-alias import errors

I'm currently learning how to create API with typescript using module-alias. When it comes to import some of them works fine, but some causes errors depite of fact that they are written in the same way.
Example: (this works fine)
import PostModel from './post.model';
import Post from '#/resources/post/post.interface';
Example (this causes error)
import PostModel from '#/resources/post/post.model';
import Post from '#/resources/post/post.interface';

See the code below that the error is pointing to.
I've been trying to figure out why is giving me that error for weeks now.
const webpack = require('webpack');
const WebpackConfigFactory = require('#nestjs/ng-universal')
.WebpackConfigFactory;
module.exports = WebpackConfigFactory.create(webpack, {
// Nest server for SSR
server: './server/main.ts'
});

WebpackConfigFactory no longer exists as Angular is now using CLI Builders to build & serve SSR apps.

Can't run require('opencv4nodejs')

I'm using macOS Monterey 12.2.1, Apple M1. And in the project directory, I installed opencv-build and opencv4nodejs by this script code:

Mocha 6, Babel 7, ES6: SyntaxError: Unexpected token export

Short solution. I had a similar problem with imports and exports.
Also, Babel did not work well with mocha version 7.2.0 and npm version 6.14.4. So I solved the problem using esm version 3.2.25.
npm install --save-dev esm
My package.json is using this:
"scripts": {
"test": "mocha -r esm --exit"
}

I was searching through the whole internet to find a solution. I came up with this:
npx mocha --require ts-node/register --require esm src/**/*.spec.ts
Or in package.json scripts (both options work, choose whichever you like):
"scripts": {
"test": "mocha -r esm -r ts-node/register src/**/*.spec.ts",
"test-ts": "ts-mocha -r esm -p tsconfig.json src/**/*.spec.ts"
}
And don't forget to add esm to devDependencies:
npm install --save-dev esm
so in package.json it is gonna be
"devDependencies": {
"esm": "^3.2.25"
}

I get your code on github, and I see your problem.
This problem is in your ol3-sidebar.js, in this file on first line you import a function from file ol/control.js, but this file is not present in your workspace. So it is giving error when running the tests.

I had the same problem. And managed to solve it after re-installing windows and it still not working.
For me it was that the project folder was on a different drive accessed via a symbolic link. I have a small SSD for boot so keep project folders on a second larger disk drive, and symlink from my home directory to this folder.
If i navigate directly to the folder it works.
I'll report this to both Mocha and Babel teams. I'm not sure who's problem this is.

I think your problem(s) come from Babel. Try first:
npx babel-upgrade
to see the modifications that the package babel-upgrade will do without applying them, and if your are satisfied:
npx babel-upgrade --write
to apply the modifications.

I had a similar problem and had to run
npm install --save-dev core-js#3
My .bablerc was:
{
"presets": [["#babel/preset-env"]]
}
