I'm trying to create a setup with static HTML partials using the HTML Webpack Plugin, but running into some errors. This is my current config:
webpack.config.js
const webpack = require('webpack');
const path = require('path');
const ExtractTextWebpackPlugin = require('extract-text-webpack-plugin');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
const OptimizeCSSAssets = require('optimize-css-assets-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
let config = {
entry: './src/index.js',
output: {
path: path.resolve(__dirname, './public'),
filename: 'app.js'
},
module: {
loaders: [{
test: /\.html$/,
loader: 'html-loader'
}],
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.scss$/,
use: ['css-hot-loader'].concat(ExtractTextWebpackPlugin.extract({
fallback: 'style-loader',
use: ['css-loader', 'sass-loader', 'postcss-loader'],
})),
},
{
test: /\.(jpe?g|png|gif|svg)$/i,
loaders: ['file-loader?context=src/assets/images/&name=images/[path][name].[ext]', {
loader: 'image-webpack-loader',
query: {
mozjpeg: {
progressive: true,
},
gifsicle: {
interlaced: false,
},
optipng: {
optimizationLevel: 4,
},
pngquant: {
quality: '75-90',
speed: 3,
},
},
}],
exclude: /node_modules/,
include: __dirname,
},
]
},
plugins: [
new HtmlWebpackPlugin({
template: './src/template.html.ejs'
}),
new ExtractTextWebpackPlugin('main.css')
],
devServer: {
contentBase: path.resolve(__dirname, './public'),
historyApiFallback: true,
inline: true,
open: true
},
devtool: 'eval-source-map'
}
module.exports = config;
if (process.env.NODE_ENV === 'production') {
module.exports.plugins.push(
new webpack.optimize.UglifyJsPlugin(),
new OptimizeCSSAssets()
);
}
template.html.ejs (located under ./src)
<%=require('./header.html')%>
<body>
testing schmesting
</body>
<%=require('./footer.html')%>
</html>
(footer.html and header.html are located under ./src)
Edit: Updated the code, still issues:
"ERROR in Error: Child compilation failed:
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type.
SyntaxError: Unexpected token (1:0)
Module parse failed: Unexpected token (1:2)
You may need an appropriate loader to handle this file type."

EDIT
(EDIT: 2017-12-20 move "loaders" to "rules")
By default, "html-webpack-plugin" parses the template as "underscore" (also called lodash) template, your "template.html" is nothing wrong, the error is caused by webpack failed to resolve 'html-loader' for your "template.html"
<%= require('html-loader!./footer.html') %>, so you need to install "html-loader" for webpack, and configure it:
In command line:
npm install html-loader
And configure it for webpack, edit webpack.config.js:
...
module: {
rules: [
// ...
{
test: /\.html$/, // tells webpack to use this loader for all ".html" files
loader: 'html-loader'
}
]
}
By now you can run "webpack" you'll see no error, BUT the generated "index.html" is not you expected, because your template file has ".html" extension, webpack now use "html-loader" to load "template.html" instead of default "lodash loader", to solve this you can rename "template.html" to "template.html.ejs" (or any other extension) to make "html-webpack-plugin" fallback. Besides there is a little bit more change on "template.html", remove "html-loader!" from it:
<%= require('./footer.html') %>
now it should work.
EDIT Post my code for reference :
/src/template.html.ejs
<!DOCTYPE html>
<html lang="en">
<head>
<title>test</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<h1>template</h1>
<%=require('./footer.html')%>
</body>
</html>
/src/footer.html
<footer>this is a footer</footer>
/webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
let config = {
entry: {
index: './src/js/index'
},
output: {
path: path.resolve(__dirname, 'dist'),
filename: '[name].js'
},
module: {
rules: [
{
test: /\.html$/,
loader: 'html-loader'
}
],
},
plugins: [
new HtmlWebpackPlugin({
template: './src/template.html.ejs'
})
]
}
module.exports = config;
/package.json
{
"name": "test",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"html-loader": "^0.5.1",
"html-webpack-plugin": "^2.30.1",
"webpack": "^3.10.0"
}
}
/src/js/index.js
console.log("A test page!");
environment:
content of "/dist/index.html" after run webpack:
<!DOCTYPE html>
<html lang="en">
<head>
<title>test</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<h1>template</h1>
<footer>this is a footer</footer>
<script type="text/javascript" src="index.js"></script></body>
</html>
As you can see content of "footer.html" is correctly inserted.
OLD ANSWER
Approach 1: Using "es6" template
npm install html-loader
module: { rules: [{ test: /\.html$/, loader: 'html-loader' }], }
interpolate flag to enable interpolation syntax for ES6 template strings, like so:plugins: [ new HtmlWebpackPlugin({ template: '!!html-loader?interpolate!src/template.html' }) ]
template.html to match ES6 template:<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> </head> <body> template </body> ${require('./footer.html')} </html>
webpack, it'll workApproach 2: Using "underscore" template
Follow "approach 1" step 1 and 2, and then:
template: './src/template.html' to template: './src/template.html.ejs' in "webpack.config.js"
