Optional dependencies in webpack

Question

for example if I want to add require("index.less") to all files and ignore this line if the file does not exists. how do I do it (including using of loaders for example).

Answer 1

One option would be to set up require.context and then check if the file exists against that.

Rough idea:

var req = require.context('./', false, /^index.less$/);

if(req.keys().includes('./index.less')) {
  req('./index.less');
}
