How to fix Sanity project start error after accidental deletion?

I'd be happy to help, but you didn't include the specific error message you're seeing! The error message is really important for diagnosing the issue. That said, here are the most common problems that occur when starting a Sanity project after accidentally deleting files:

Most Common Issues:

1. Missing sanity.config.ts or sanity.config.js - This is your main configuration file. If it's gone, you'll get an error about missing configuration. You'll need to recreate it with at minimum:

   import {defineConfig} from 'sanity'
   
   export default defineConfig({
     name: 'my-studio',
     title: 'My Studio',
     projectId: 'your-project-id',
     dataset: 'production',
     plugins: [],
     schema: {
       types: [],
     },
   })

   The defineConfig function is the core configuration utility that sets up your Studio. The projectId and dataset are configured directly in this file.

2. Missing node_modules or package.json - If you deleted these, run:

   npm install

3. Missing schema files - If you deleted your schema folder or files within it, the Studio might fail to start with schema-related errors. You'll need to restore those or create new schema definitions in your schema directory.

4. Missing .sanityrc or project metadata - Some older projects may have project-specific configuration files that need to be restored.

Quick Recovery Steps:

• If you're using Git: Check git status to see what was deleted and restore with git checkout <filename> or git restore <filename>
• If you have backups or the project is in version control, restore from there
• If you need to completely reinitialize: You can run sanity init in a new folder and reconnect to your existing project. This command will walk you through an interactive setup process.
