I'm learning Node.js and am using a Node-based Azure Function.
I'm trying to bring in Chalk, to log coloured messages to the console.
However, all of the below fail (in my main index.js file).
module.exports = async (ctx, req) => {
const chalk = require('chalk');
return console.log(chalk.blue('Hello world!'));
Despite being the approach recommended in this answer, this results in a console error that says:
Exception: require() of ES Module C:...\node_modules\chalk\source\index.js from C:...\index.js not supported. Instead change the require of C:...\chalk\source\index.js in C:...\index.js to a dynamic import() which is available in all CommonJS modules.
If I do as the error suggests, and use
const chalk = async import('chalk')
...I then get
Exception: chalk.blue is not a function
...even though console.log(chalk) does seem to show the Chalk API and its various properties.
The Chalk docs themselves recommend this:
module.exports = async (ctx, req) => {
import chalk from 'chalk'
return console.log(chalk.blue('Hello world!'));
That yields an error saying I can't use import outside of a module (but surely I'm in one?)
Same as three ^^ but moving the import outside module.exports:
import chalk from 'chalk'
module.exports = async (ctx, req) => {
return console.log(chalk.blue('Hello world!'));
...yields the same error.
I'm sure this is a basic error but I can't find what I'm doing wrong so I'd be so grateful if someone could help. Thank you!
When you import something using import as a function(lazy import), It'll return an object with a default property and all exported properties. That you should use to access the module.
const module = async import('chalk')
const chalk = module.default
console.log(chalk.red('Hello world!'))
