next-compose-plugins is a great way to keep your next.config.js file clean
https://github.com/cyrilwanner/next-compose-plugins
example:
const withPlugins = require('next-compose-plugins');
const sass = require('@zeit/next-sass');
module.exports = withPlugins([
[sass],
]);
As it relates to you:
const nextTranslate = require("next-translate");
const withImages = require("next-images");
const withPlugins = require("next-compose-plugins");
module.exports = withPlugins([
withImages,
nextTranslate
], { other configs here that aren't plugins })
I'm not sure about the shape of nextTranslate, but that's the gist of it.
