I am currently attempting to incorporate a variable into my app.js file during the build process. For instance:
//app.js
var myvar = {{set_from_cli}};
Afterwards, I would like to execute something such as webpack -p --myvar='abc' which would produce the following output:
//bundle.js
var myvar = 'abc';
I have conducted some research but so far have not been able to find the right solution or terminology to achieve this. Any help is greatly appreciated.
To access the variable myvar in your webpack.config.js file, you can do so using this code snippet (assuming you have installed minimist):
var argv = require('minimist')(process.argv.slice(2));
console.log(argv.myvar);
If you want to include it in your bundle, you can utilize the DefinePlugin. This is how you would define it within your plugin:
plugins: [
new webpack.DefinePlugin({
MYVAR: JSON.stringify(argv.myvar)
})
]
Then in your code, you can access the variable like this:
var myvar = MYVAR;
Make any necessary adjustments as needed.
