How to fix “Module build failed: SyntaxError: Unexpected token” error when using JSON file in react? - json

Question

I am following a react tutorial by Brian holt and i need to import .json file inside my react component like this :
code
When I try to build my project i was getting
ERROR in ./data.json
Module build failed: SyntaxError: Unexpected token, expected
like this:
Error caption in terminal
at first i thought that it was an eslint issue but it seems that it happens on the build step, i tried adding a json-loader to webpack but without any success.
Webpack Version:
2.6.1
Babel Core Version:
6.24.1
Babel Loader Version:
7.0.0,
this is my webpack config file :
const path = require('path')
module.exports = {
context: __dirname,
entry: './js/clientApp',
devtool: 'cheap-eval-source-map',
output: {
path: path.join(__dirname, 'public'),
filename: 'bundle.js',
publicPath: '/assets/'
},
resolve: {
extensions: ['.js', '.jsx', ',json']
},
devServer: {
publicPath: '/public/',
port: 2110,
open: true,
historyApiFallback: true
},
stats: {
colors: true,
reasons: true,
chunks: true
},
module: {
rules: [
{
enforce: 'pre',
test: /\.jsx?/,
loader: 'eslint-loader',
exclude: /node_modules/
},
{
test: /\.jsx?/,
loader: 'babel-loader'
}
]
}
}
and this is my .babelrc file :
{
"presets": [
"react", ["env", {
"targets": {
"browsers": "last 2 versions"
},
"loose": true,
"modules": false
}]
]
}
Any suggestions please ?

Answer 1

Regular Expression
The test property identifies which file or files should be transformed.
The problem is the regular expression on your rules:
{ test: /\.jsx?/ }
Your telling webpack to use babel-loader with any file extension starting with .js or .jsx
So as you can see .json match the test.
Solution
$ - matches anything until the end of the string
To fix this just replace ? with $, see the example below:
module: {
rules: [
{
test: /\.jsx$/,
loader: 'babel-loader'
}
]
}
