Envio Community Update No. 06

Cover Image Envio Developer Community Update No.6

Great to have you back for our sixth community update and our first one of 2024! Just like the previous updates, we're thrilled to give you an insider's peek into the latest and greatest adventures of what the Envio team has been shipping over the past month.

Notable feature updates include ‘Async Mode’ which eliminates the need for users to add required_entities to their config to access them in their loaders. Developers can now define 'Async Mode' to execute custom effects in event handlers, bolt-on async queries like smart contract view functions or fetching data from IPFS. Async mode enables developers to write handlers without loaders, loading directly from within the handler. Chain IDs are now also accessible inside the event handler context (see the technical overview below for more details).

New HyperSync Networks ⚡​

We’re also excited to announce that Envio HyperSync has added even more significant updates to existing networks and added new and enhanced indexing support for developers building on Base Sepolia, Optimism Sepolia, Arbitrum Nova, Aurora, Aurora Testnet, Harmony, ZORA, Public Goods Network, C1 Milkomeda, Flare and Mantle with many more in the pipeline.

For a full list of currently supported chains on HyperSync visit our docs.

We’re also incredibly pleased to announce that Envio has been officially listed on the official Avalanche, Evmos, Celo, OKTC and Fantom ecosystems as one of the best blockchain indexing solutions for developers building on their networks.

Case Study: Jarvis Network 📈​

In addition, we’re incredibly thrilled to announce that Jarvis Network has integrated Envio and our multi-chain indexing capabilities to streamline their process of accessing and aggregating real-world asset price data secured by Chainlink’s industry-leading price data feeds across various blockchain networks, including Polygon, Optimism, BNB, and Arbitrum.

Upcoming Events ⭐​

Technical Overview 🏗️​

Current release: v0.0.29 🚀

Over the past month, we released three new versions of Envio (v.0.0.27 → v.0.0.29).

What's changed:​

v0.0.27​

Changes:

  • Async handlers allow the fetching or processing of data asynchronously when required. This allows data to be fetched from IPFS, or other contract states to be examined that aren't available in the event.
  • We have made the conversion from synchronous to asynchronous handlers extremely easy:
  • add isAsync: true to the config of any event you want to be asynchronous.
  • make the handler function a promise, and await any get calls on the context since they are promises too in async mode.
  • Other notes:
  • You cannot have async and sync handlers for the same event.
  • Async handlers are potentially less performant than synchronous handlers, so use them only when you need to.
  • Async handlers allow 'loaderless' handlers, so you can directly interact with the database. This has some performance costs but is a benefit to users.

User Experience and Logging Enhancements:

  • Improved user log labels for better clarity for debugging and in the hosted service.
  • Added more context to user logs for future UI that can enable future UI improvements.
  • Other formatting improvements such as changing from to fromBlock and to to toBlock for consistency between logs.

Contract Import and Error Handling:

  • requiredEntities is optional for all handlers, and when omitted all entities will be available in your handlers.
  • Handled params named id during contract import process, fixed tests, and removed unused imports.
  • Supported nameless params in contract import for flexibility.
  • Updated and aligned error codes with documentation for consistency.

Network and Blockchain Enhancements:

  • Expanded HyperSync support by adding 11 new networks!
  • Improved integration tests to ensure new chains work correctly.

General Improvements and Fixes:

  • Updated entity fields and event parameters to always be uncapitalized for consistency.
  • Fixed various tests to ensure reliability.
  • Added Chain ID to the event as per documentation, essential for multi-chain indexing. It was a bug that it was omitted.

Dependency Updates:

  • Updated multiple dependencies across various scenarios and components for security and performance.

v0.0.28​

Changes:

  • Small patch release fixing issues with contract import of contracts with an event param ID.
  • Events with a param name of ID no longer break the contract import functionality, by making the entities param have the name event_id.
  • Small re-wording to some user-facing logs to make them clearer.

V0.0.29​

Changes:

  • GraphQL Engine Non-Root Mode: Enhanced security by running the GraphQL engine as a non-root user.
  • Improved Logging: More informative logging for fetchers catching up with the chain head.
  • NPM Package Installation Ease: Users can now install npm packages in their indexer without the -w flag.

Enhancements and Fixes:

  • Fixed spelling errors in codgen template files.
  • Updated error messages for better clarity.
  • Fix bug for allowing contract import of contracts with empty tests, and associated testing.
  • Updated the Greeter template with fixes and improvements.
  • Improved error messages for missing handler or loader specifications.
  • Added shamefully-hoist to .npmrc to avoid issues experienced on some setups with generated folder dependencies.
  • Resolved issues with contract imports and ABI source descriptors.
  • Corrected TypeScript import errors and standardized naming conventions.
