[SOLVED] NodeJS - How do I call separate imports based on 'if' condition for ES Modules?

NodeJS - How do I call separate imports based on 'if' condition for ES Modules?

Followed a tutorial that uses CommonJS to export/require different keys based on the environment. How do I get it to work with ES Modules import/export?

This was the code he used:

if (process.env.NODE_ENV === "production") {
module.exports = require('./prod')
else {
module.exports = require('./dev')
> }

Solution

First of all, you have to import the functions/components.

import Production from "./prod"
import Development from "./dev"

Then you can check the condition, and assign the specific function/component to a variable. Finally, you can export it.

let defaultExport

if (process.env.NODE_ENV === "production") {
  defaultExport = Production
} else {
  defaultExport = Development
}

export default defaultExport

The full code will look like this

import Production from "./prod"
import Development from "./dev"

let defaultExport

if (process.env.NODE_ENV === "production") {
  defaultExport = Production
} else {
  defaultExport = Development
}

export default defaultExport
