Cannot import ES modules with "node" command in my Nuxt project

  • My nuxt project uses serverMiddleware defined in nuxt.config.js as serverMiddleware: ['~/api']
  • All the files inside my api directory use import and export statements and work perfectly when I run npm run dev
  • I also have a seeders directory which contains a bunch of database seeder files with each one having import and export statements
  • When I run it from package.json with "seed:dev": "cross-env NODE_ENV=development node ./api/db/seeders",

I get the following error

(node:12212) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.

import feeds from './feeds-data'
^^^^^^

How do I run the database seeders which use import export statements the way nuxt runs my other files?

Solution

  • What is your Node.js version ?

    Depending of it, you have several options as detailed here: https://stackoverflow.com/a/45854500/8816585

    The most simple is still to have a "type": "module" in your package.json as the error tells you !

    The latest LTS is: 14.16.0 and it may not be supported by all the platforms, so beware.

    PS: it's a bit more simple in v15 if I'm not mistaken but this version is still experimental.

    TLDR: nothing related to Nuxt in any way. ^^
