What is the problem ?
I’ve started using webpack2 (to be precise, v2.3.2
) and after re-creating my config I keep running into an issue I can't seem to solve I get (sorry in advance for ugly dump):
ERROR in ./src/main.js
Module not found: Error: Can't resolve 'components/DoISuportIt' in '[absolute path to my repo]/src'

package.json
{
"version": "1.0.0",
"main": "./src/main.js",
"scripts": {
"build": "webpack --progress --display-error-details"
},
"devDependencies": {
...
},
"dependencies": {
...
}
}
In terms of the browser
field it's complaining about, the documentation I've been able to find on this is: package-browser-field-spec
. There is also webpack documentation for it, but it seems to have it turned on by default: aliasFields: ["browser"]
. I tried adding a browser
field to my package.json
but that didn't seem to do any good.
webpack.config.js
import path from 'path';
const source = path.resolve(__dirname, 'src');export default {
context: __dirname,
entry: './src/main.js',
output: {
path: path.resolve(__dirname, 'dist'),
filename: '[name].js',
},
resolve: {
alias: {
components: path.resolve(__dirname, 'src/components'),
},
extensions: ['.js', '.jsx'],
},
module: {
rules: [
{
test: /\.(js|jsx)$/,
include: source,
use: {
loader: 'babel-loader',
query: {
cacheDirectory: true,
},
},
},
{
test: /\.css$/,
include: source,
use: [
{ loader: 'style-loader' },
{
loader: 'css-loader',
query: {
importLoader: 1,
localIdentName: '[path]___[name]__[local]___[hash:base64:5]',
modules: true,
},
},
],
},
],
},
};
src/main.js
import DoISuportIt from 'components/DoISuportIt';
src/components/DoISuportIt/index.jsx
export default function() { ... }
For completeness, .babelrc
{
"presets": [
"latest",
"react"
],
"plugins": [
"react-css-modules"
],
"env": {
"production": {
"compact": true,
"comments": false,
"minified": true
}
},
"sourceMaps": true
}
What am I doing wrong/missing?
The Perfect Solution is …
Turned out to be an issue with Webpack just not resolving an import — talk about horrible horrible error messages :(
// Had to change
import DoISuportIt from 'components/DoISuportIt';// To (notice the missing `./`)
import DoISuportIt from './components/DoISuportIt';
