Because JavaScript can be written for both server and browser, webpack offers multiple deployment targets that you can set in your webpack configuration.
To set the target
property, you set the target value in your webpack config:
webpack.config.js
module.exports = {
target: 'node',
};
In the example above, using node
webpack will compile for usage in a Node.js-like environment (uses Node.js require
to load chunks and not touch any built in modules like fs
or path
).
Each target has a variety of deployment/environment specific additions, support to fit its needs. See what targets are available.
Although webpack does not support multiple strings being passed into the target
property, you can create an isomorphic library by bundling two separate configurations:
webpack.config.js
const path = require('path');
const serverConfig = {
target: 'node',
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'lib.node.js',
},
//…
};
const clientConfig = {
target: 'web', // <=== can be omitted as default is 'web'
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'lib.js',
},
//…
};
module.exports = [serverConfig, clientConfig];
The example above will create a lib.js
and lib.node.js
file in your dist
folder.
As seen from the options above, there are multiple deployment targets that you can choose from. Below is a list of examples and resources that you can refer to.
