Webflow CMS to Sanity Migration Tool

This tool assists users in migrating their Webflow content to Sanity. It fetches collections from Webflow and allows users to select which site and collection they wish to migrate. After selection, the tool maps Webflow items to a predefined Sanity schema, provided by the user, and uploads them to Sanity.

This code contains a demo mapping function for how to handle:

Migrating images from Webflow to Sanity.
Migrating files from Webflow to Sanity.
Migrating Webflow Rich Text Content (HTML) to Sanity Block Content.

Node.js
node-fetch, axios, readline, @sanity/client, @sanity/block-tools, @sanity/schema, jsdom, and dotenv npm packages.
