Near is a decentralized application platform that allows developers to build blockchain-based apps like games, financial services, social media etc. Developers write smart contracts in Rust that run on the Near blockchain. They can leverage Near's features like high scalability, low fees and fast transactions to build user-friendly dapps.

To build on Near, developers need to learn languages like Rust and AssemblyScript to code smart contracts and frontends. They have to stake NEAR tokens to deploy dapps and smart contracts to the blockchain. Developers can earn rewards when users interact with their dapps. They can also contribute to improving Near's open source code. The developer tools, documentation and community provided by Near empower developers to build secure, scalable decentralized apps. In summary, developers are crucial for creating dapps on Near and growing its blockchain ecosystem.

3. Almost 1,000 of the repositories are written in JavaScript, and 972 repositories belong to TypeScript.

4. The 'Nearcore' Repository has the highest number of forks, with 523 forks.

5. In terms of issue count, 'NearCore' takes the lead with 773, while 'Near-wallet' comes in second with 248.

6. Most of the repositories are owned by 'Near' Devs, with over 200 repos. In the second rank, we have 'Near-example' with more than 100 repos.

with the help of near.core.fact_developer_activity table we can collect caiable information about Repositories and devs Activity of Nea.

here we will focus on three parts: give you an overview of the Repositories (Count,language, etc) - identify top Repositories base ob multiple metrics - identify Top Devs
