What are NEAR Components?

NEAR Components are a new way to build web applications. They are composable, reusable and decentralized.

Familiar to Web Developers​

NEAR Components are built on top of React Components, meaning that they:

  • Handle input through the props variable
  • Handle state through the useState hook
  • Handle side effects through the useEffect hook

In contrast with React, NEAR Components are not wrapped in a function or class definition.

Indeed, when writing a NEAR Component, you focus on writing the body of the component, which is a function that returns the JSX to be rendered.


NEAR Native​

NEAR Components can readily interact with smart contracts in the NEAR Blockchain. While view methods are free to query by anyone, call methods require the user to be logged in.

Social from the Get-Go​

NEAR Components are easily integrated with NEAR Social, a social network built on NEAR.

Fully On-Chain & Easily Composable​

Leveraging the cheap storage and computation of the NEAR Blockchain, NEAR Components' code is stored fully on-chain in the SocialDB smart contract (social.near).

Once deployed, a component can be imported and used by any other component. Composing components as LEGO blocks allows you to build complex applications.

Multi-Chain by Design​

NEAR Components can easily interact with Ethereum compatible blockchains, helping to easily create decentralized frontends for multi-chain applications.
