Frequently Asked Questions

On this page we hope to document frequently asked questions in regards to using the adze library.

How can I make Adze work with NestJS?

Problem

"When installing Adze in NestJS I get the following error:"

Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/andrewstacy/Projects/personal/adze/dist/index.js from /Users/andrewstacy/Projects/personal/project-name/dist/logger.js not supported.

Solution

NestJS currently does not support importing of ES Modules directly. There is currently an open PR on GitHub to resolve this.

There are currently two preferred options for working around this limitation:

Use Experimental Require Module Flag

The easiest way to work around this issue is to use the node --experimental-require-module flag. Keep in mind that this will only work with node version >= 22.x and it is an experimental feature that can change at any time with new node versions.

Change your nestjs scripts to look like this:

{
  "scripts": {
    "start": "nest start -e 'node --experimental-require-module'",
    "start:dev": "nest start --watch -e 'node --experimental-require-module'",
    "start:debug": "nest start --debug --watch -e 'node --experimental-require-module'",
    "start:prod": "node --experimental-require-module dist/main"
  }
}

Use Helpers

This method is a bit safer, but is also quite ugly. It requires the use of the dynamic import function with means that you'll have to await the function each time you want a copy of your adze logger.
