I'm using webpack for a Node framework that I'm building (though I should probably use gulp, admittedly). When I include the EJS module, webpack includes it in the compiled source, even though I explicitly tell it to exclude the node_modules dir.
module.exports = {
context: __dirname,
target: 'node',
// ...
output: {
libraryTarget: 'commonjs'
// ...
},
module: {
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader?{ "stage": 0, "optional": ["runtime"] }'
}
]
}
};
As you can see, I have a test for JS files, and I tell it to exclude node_modules; why is it ignoring my exclude?

From your config file, it seems like you're only excluding node_modules from being parsed with babel-loader, but not from being bundled.
In order to exclude node_modules and native node libraries from bundling, you need to:
Add
target: 'node'to yourwebpack.config.js. This will define NodeJs as the environment in which the bundle should run. For webpack, it changes the chunk loading behavior, available external modules and generated code style (ie. usesrequire()for NodeJs) it uses during bundling.Set the
externalPresetsofnodetotrue. As of Webpack@5, This configuration will exclude native node modules (path, fs, etc.) from being bundled.Use webpack-node-externals in order to exclude other
node_modules.
So your result config file should look like:
var nodeExternals = require('webpack-node-externals');
...
module.exports = {
...
target: 'node', // use require() & use NodeJs CommonJS style
externals: [nodeExternals()], // in order to ignore all modules in node_modules folder
externalsPresets: {
node: true // in order to ignore built-in modules like path, fs, etc.
},
...
};
If you ran into this issue when using TypeScript, you may need to add skipLibCheck: true in your tsconfig.json file.
Try use absolute path:
exclude:path.resolve(__dirname, "node_modules")
This worked for me:
exclude: [/bower_components/, /node_modules/]
module.loaders
A array of automatically applied loaders.
Each item can have these properties:
test: A condition that must be met
exclude: A condition that must not be met
include: A condition that must be met
loader: A string of "!" separated loaders
loaders: A array of loaders as string
A condition can be a RegExp, an absolute path start, or an array of one of these combined with "and".

try this below solution:
exclude:path.resolve(__dirname, "node_modules")
