webpack supports export in the configuration file webpack.config.js , which accepts two parameters
env : environment argv : parameter all the parameters you pass in are in argv , so you can do this
// webpack.config.js
module.exports = (env, argv) => {
let abc=argv.abc
return {
// ...webpack config
}
}
then start it like this
webpack-dev-server --open --abc=11111111 if you want to use it in your code, you can use DefinePlugin
new webpack.DefinePlugin({
ABC : JSON.stringify(abc)
})in code
if (ABC==='11111111'){
alert(abc)
}const json = require('../../package.json')
