🔼 Previewing Upcoming Subgraph Features in graph-node 0.33.0 🔼

In last month's Builders Newsletter, we saw snippets demonstrating new features such as Arweave support, File Data Sources spawning File Data Sources, polling block handlers, and initialization handlers. All of this was made possible by the graph-node0.32.0’s release. What a month!

We are now preparing for graph-node 0.33.0’s release which should be coming out soon! This update will bring some significant upgrades:

DataSourceContext In The Subgraph Manifest

Passing data from one handler to another handler while templating was previously possible in our subgraphs mappings through using Data Source Context, but now this feature is available in our subgraph.yaml!

This feature will be useful for templating chain-specific data in subgraphs that use the same codebase across multiple chains. Once 0.33.0 is released, check it out!

name: Factory
    network: mainnet
    context:
      foo:
      bool_example:
        type: Bool
        data: true
      int8_example:
        type: Int8
        data: 64
      big_decimal_example:
        type: BigDecimal
        data: 10.99
      bytes_example:
        type: Bytes
        data: \"0x68656c6c6f\"
      list_example:
        type: List
        data:
          - type: Int
            data: 1
          - type: Int
            data: 2
          - type: Int
            data: 3
      big_int_example:
        type: BigInt
        data: \"1000000000000000000000000\"
      string_example:
        type: String
        data: bar
      qux:
        data: \"bar\"
      int_example:
        type: Int
        data: 42

endBlock Defined in subgraph.yaml

When building a subgraph, we define the startBlock from which the subgraph begins its indexing. Now, we also have endBlock to refine our subgraphs focus to only a specific set of blocks!

source:
  address: '0x...'
  abi: Contract
  startBlock: 1000000
  endBlock:  1500000

Major performance boost incoming Substreams-powered subgraphs

Significant performance improvements have been achieved for substreams-based subgraphs by moving substreams processing to the block.

Substreams-powered subgraphs published to The Graph Network are a key part improving the speed and unbreakable nature of decentralized indexing. Try building a Substreams-powered subgraph, then publish that Substreams-powered subgraph to The Graph Network to ensure your data pipeline is decentralized!

🏗️ Building With The Graph - Workshops 🏗️

The Graph Builders Office Hours - Thursdays 5pm UTC

Jump into The Graph Builders Office Hours every Thursday at 5pm UTC hosted by Edge & Node Developer Relations Engineer Kevin Jones in The Graph Discord. Each session includes live workshops and Q&A discussions with developers who are building in The Graph Ecosystem.

Start building fast with previous The Graph Builders Office Hours workshops!

• Dive into some new subgraph features - Initialization Handlers and Polling Handlers
• Build with Messari Standard Subgraphs
• Get hacking fast with a hackathon starterkit that uses The Graph
• Build a dapp with Scaffold-Eth 2 and The Graph
• See how powerful Substreams-powered subgraphs can be
• Dive into subgraph data analytics with Playgrounds
• Bring off-chain data to subgraphs with File Data Sources

There were some incredible submissions for the EthAccra and EthGlobal NYC 2023 hackathons!

Get inspired by the grand-prize winners 🥇Challenge Pool 🥇TeachAI and 🥇Leverage Labs! Find further inspiration by checking out the full list of EthAccra 2023 hackathon submissions and EthGlobal NYC 2023 hackathon submissions!

The Graph will be represented at EthRome and EthMiami as well - we hope to see you there!

Want to Participate in The Graph Ecosystem?

⚙️ Build with The Graph BuildersDAO ⚙️

Join The Graph BuildersDAO!

The Graph BuildersDAO is a community of collaborative developers who provide their building services to dapps and protocols.

This collaborative community is looking for builders with various levels of experience in smart contracts, Rust, frontend frameworks, DevOps, subgraphs and Substreams to join and participate on a variety of projects.

Also, if there’s a project that needs some builder-power, The Graph BuildersDAO is a great resource that can build a custom subgraph or Substream! Get in touch!

➕ Sign Up For The Graph Billing Subscriptions Beta Program ➕

The Graph Billing Subscriptions is an alternative to The Graph’s existing Pay As You Go billing system that we hope will simplify payments to just “set it and forget it”.

Sign up for The Graph Subscriptions Beta!
