In certain scenarios, the front directory may not be writable. When this is the case, writing the patched `index.html` should be skipped just like when the file does not exist. For brevity, I have replaced the `existsSync` check with a try-catch that catches any errors occuring during read or write of the index file. The alternative would be `fs.accessSync` with `W_OK`, but that would still throw an error if the file is not writable so I think it is reasonable to skip it altogether and go straight for the read and write attempts. A specific scenario where the front directory is immutable is NixOS, where the directory may be located in the read-only nix store.
