I have trying to add react in the shopify theme. So configured react, webpack, babel manually. Webpack.dev.js

const merge  = require('webpack-merge');
const common = require("./webpack.common.js")

module.exports = merge(common, {
  mode: "development",
  devtool: "inline-source-map",
  watch: true
})

But I am getting error, merge is not a function. Thanks in advance.

In a new version of webpack-merge, It is imported like below.

const { merge } = require('webpack-merge');

As from version 5 of webpack-merge, the merge function is now named export instead of a default export.

Before version 5

const merge = require('webpack-merge');

From version 5

const merge = require('webpack-merge').merge;

// or       

const { merge } = require('webpack-merge');

If you are using ES modules, then you should do as:

import { merge } from "webpack-merge"

I use a ES6 webpack config, so I use webpack-merge@4.2.1 ...

import merge from "webpack-merge"

you can also leverage merge by renaming it like below:

const { merge: webpackMerge } = require("webpack-merge");

by this way you still using the same name of old api of the package!

I have imported like below,

const { merge } = require("webpack-merge");

and used as

const mergedConfig = merge(config, customConfig);
