Meme Factory Subgraph

Getting started

Like other subgraphs, the Meme Factory subgraph is built with

# Once (installs dependencies)
yarn

# Each time you want to build
yarn build-ipfs [--verbosity debug]

However, in order to index the subgraph, graph-node needs to run against a Ganache testnet rather than a real Ethereum node. This is because the Meme Factory contracts have not been deployed to a public Ethereum network yet and we need some test data and events to index.

Running the testnet

In order to bring up the Ganache testnet, run the following two commands:

# Once
tar xf ganache-db.tar.bz2

# Each time
yarn testnet

This will run Ganache on http://localhost:8546, allowing to run graph-node as follows:

graph-node                             \
  ...                                  \
  --ethereum-rpc http://localhost:8546 \
  --subgraph IPFS_HASH

TODO

Identify if there are other contracts/events we should watch
Identify how to handle remaining types and fields (see questions in GraphQL schema)

Missing features already identified

GraphQL interfaces
BigInt math (required for adding votes for and votes against in challenges)
Aggregation / counting

Reference

This subgraph manifest is based on the following MemeFactory resources:
