pre and post loaders are loaders ;)

usage options

But usually a loader isn't called with the source, is it?

from webpack.

It is. It's called with the content of the file which it should "load". Take a look at some of my loaders to see examples.

You can imagine loaders as some kind of transformation applied to the file content before including it in the bundle.

require("loaderA!loaderB!./file.txt");

// while compiling: (simplified)
var loaderA = require("loaderA");
var loaderB = require("loaderB");
addToBundle(loaderA(loaderB(readFile("./file.txt"))));

pre/post loaders work the same but you just don't specify them in the require call.

Ah ok. So I don't have to use fs.readFile within a loader.

from webpack.

sokra avatar sokra commented on March 28, 2024

No, you can and should use the parameter. Elsewise chaining of loader will not work correctly.

from webpack.

Oops. I will adjust that.
