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.

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
