DAOstack Subgraph
DAOstack subgraph for TheGraph project. A feature article is available here.
Our latest gratest master branch subgraph.
Getting started
git clone https://github.com/daostack/subgraph.git && cd subgraph
npm install
Testing
Run the tests in the host container:
npm run docker:run
npm run test
npm run docker:stop
The tests are run with jest, which takes a number of options that may be useful when developing:
npm run test -- --watch # re-run the tests after each change
npm run test -- test/integration/Avatar.spec.js # run a single test file
Commands
migrate
- migrate contracts to ganache and write result tomigration.json
.codegen
- (requiresmigration.json
) automatically generate abi, subgraph, schema and type definitions for required contracts.test
- run integration test.deploy
- deploy subgraph.deploy:watch
- redeploy on file change.
Docker commands (requires installing docker
and
docker-compose
):
docker <command>
- start a command running inside the docker container. Example:npm run docker test
(run intergation tests).docker:stop
- stop all running docker services.docker:rebuild <command>
- rebuild the docker container after changes topackage.json
.docker:logs <subgraph|graph-node|ganache|ipfs|postgres>
- display logs from a running docker service.docker:run
- run all services in detached mode (i.e. in the background).
Exposed endpoints
After running a command with docker-compose, the following endpoints will be exposed on your local machine:
http://localhost:8000/subgraphs/name/daostack
- GraphiQL graphical user interface.http://localhost:8000/subgraphs/name/daostack/graphql
- GraphQL api endpoint.http://localhost:8001/subgraphs/name/daostack
- graph-node's websockets endpointhttp://localhost:8020
- graph-node's RPC endpointhttp://localhost:5001
- ipfs endpoint.- (if using development)
http://localhost:8545
- ganache RPC endpoint. http://localhost:5432
- postgresql connection endpoint.
Add a new contract tracker
In order to add support for a new contract follow these steps:
Create a new directory
src/mappings/<contract name>/
Create 4 files:
src/mappings/<contract name>/mapping.ts
- mapping code.src/mappings/<contract name>/schema.graphql
- GraphQL schema for that contract.src/mappings/<contract name>/datasource.yaml
- a yaml fragment with:abis
- optional - list of contract names that are required by the mapping.entities
- list of entities that are written by the the mapping.eventHandlers
- map of solidity event signatures to event handlers in mapping code.
test/integration/<contract name>.spec.ts
Add your contract to
ops/mappings.json
. Under the JSON object for the network your contract is located at, under the"mappings"
JSON array, add the following.If your contract information is in the
migration.json
file specified (default is the file under@daostack/migration
folder, as defined in theops/settings.js
file):{ "name": "<contract name as appears in `abis/arcVersion` folder>", "contractName": "<contract name as appears in migration.json file>", "dao": "<section label where contract is defined in migration.json file (base/ dao/ test/ organs)>", "mapping": "<contract name from step 2>", "arcVersion": "<contract arc version>" },
If your contract does not appear in the migration file:
{ "name": "<contract name as appears in `abis/arcVersion` folder>", "dao": "address", "mapping": "<contract name from step 2>", "arcVersion": "<contract arc version under which the abi is located in the `abis` folder>", "address": "<the contract address>" },
(Optionally) add a deployment step for your contract in
ops/migrate.js
that will run before testing.
Add a new dao tracker
To index a DAO please follow the instructions here: https://github.com/daostack/subgraph/blob/master/documentations/Deployment.md#indexing-a-new-dao
Add a new datasource template
Datasource templates allow you to index blockchain data from addresses the subgraph finds out about at runtime. This is used to dynamically index newly deployed DAOs. To add a new contract ABI that can be used as a template within your mappings, modify the ops/templates.json
file like so:
{
"templates": [
...,
{
"name": "<contract name as appears in `abis/arcVersion` folder>",
"mapping": "<name of the `src/mappings/...` folder to be used with this contract>",
"start_arcVersion": "<contract arc version under which the abi is located in the `abis` folder>",
"end_arcVersion": "(optional) <contract arc version under which the abi is located in the `abis` folder> if not given, all future versions of this `name`'s contract ABI will be added as a template for this mapping"
}
]
}
Deploy Subgraph
To deploy the subgraph, please follow the instructions below:
If you are deploying to The Graph for the first time, start with installing the Graph CLI:
npm install -g @graphprotocol/graph-cli
Then follow this by logging into your Graph Explorer account using:graph auth https://api.thegraph.com/deploy/ <ACCESS_TOKEN>
It is also recommended to read this guide: https://thegraph.com/docs/deploy-a-subgraph
Create a
.env
file containing the following:network="<TARGET_NETWORK>" subgraph="<YOUR_SUBGAPH_NAME>" # Not necessary for Docker deployment graph_node="https://api.thegraph.com/deploy/" ipfs_node="https://api.thegraph.com/ipfs/" access_token=<YOUR_ACCESS_TOKEN> # Not necessary for The Graph server postgres_password=<YOUR_PASSWORD> ethereum_node="https://<TARGET_NETWORK>.infura.io/<INFURA-KEY>" start_block=<START INDEX BLOCK> (default is 0)
Run:
npm run deploy
Release subgraph images on docker hub
The repository provides a release.sh
script that will:
- (re)start the docker containers and deploy the subgraph
- commit the images for ipfs and postgres and push these to docker hub
The docker images are available as:
daostack/subgraph-postgres:${network}-${migration-version}-${subgraph-version}
daostack/subgraph-ipfs:${network}-${migration-version}-${subgraph-version}
Blacklist a malicious DAO
Add the DAO's Avatar address to the ops/blacklist.json
file in the proper network array. For example, blacklisting 0xF7074b67B4B7830694a6f58Df06375F00365d2c2
on mainnet would look like:
{
"private": [],
"kovan": [],
"rinkeby": [],
"mainnet": [
"0xF7074b67B4B7830694a6f58Df06375F00365d2c2"
]
}
