Juno has sharpened its serverless functions, making them clearer, more detailed, and better integrated with the latest stack. Developers working with Rust-based features now have a more refined structure to navigate, packed with additional references and upgraded examples. The update strengthens the ability to extend the native capabilities of Satellites, streamlining event-driven execution within smart contracts.
Functions allow developers to embed custom logic directly into the blockchain environment by responding to document and asset operations. By defining hooks that automatically trigger on creation, update, or deletion events, developers gain a toolset that adapts dynamically to blockchain interactions. These hooks run asynchronously, ensuring that execution remains independent of the caller’s action. This means users receive feedback on their operations without delay, even before hooks begin their execution. This non-blocking mechanism ensures smooth performance without disrupting the flow of update calls to the Satellite.
Reliability is built into the structure, as hooks only trigger when there are no errors in prior operations. This ensures a stable and consistent execution flow, reinforcing trust in automated processes. Developers also have the flexibility to decide whether to activate these custom hooks, as they are not enabled by default. For those looking to further refine control, custom assertions expand the rule set of Satellites. Unlike hooks, these assertions work synchronously and must return a result, adding another layer of precision to smart contract interactions.
This update enhances the overall experience for developers seeking efficient and customisable serverless behaviours within Juno’s blockchain ecosystem. With a refined framework and a more accessible structure, these improvements make the integration of smart contract automation more seamless than ever.
