Add graph init with --from-example and --from-contract modes #224

Jannis · 2019-03-07T12:19:13Z

This supersedes #216 by supporting both the old and the new graph init via

--from-example and
--from-contract <address>

mode flags.

TODO

Update README
Update docs on https://thegraph.com/docs/

Example usage

If all arguments are provided for either mode, graph init will run in non-interactive mode:

# From the example subgraph:
graph init --from-example user/subgraph-name output-dir
graph init --from-example --allow-simple-name subgraph-name output-dir

# From an existing contract:
graph init \
  --from-contract 0xF87E31492Faf9A91B02Ee0dEAAd50d51d56D5d4d \
  --network mainnet \
  user/subgraph-name \
  output-dir

If one or more arguments are not provided, graph init will run the user through an interactive form to create a subgraph from an existing contract, pre-populating fields with the provided values:

$ graph init --from-contract 0xF87E31492Faf9A91B02Ee0dEAAd50d51d56D5d4d jannis/decentraland-land
✔ Subgraph name · jannis/decentraland-land
✔ Directory to create the subgraph in · land
✔ Ethereum network · mainnet
✔ Contract address · 0xF87E31492Faf9A91B02Ee0dEAAd50d51d56D5d4d
✔ Fetching ABI from Etherscan
———
  Generate subgraph from ABI
  Write subgraph to directory
✔ Create subgraph scaffold
✔ Initialize subgraph repository
✔ Install dependencies with yarn
✔ Generate ABI and schema types with yarn codegen

Subgraph jannis/decentraland-land created in land

Next steps:

  1. Run `graph auth https://api.thegraph.com/deploy/ <access-token>`
     to authenticate with the hosted service. You can get the access token from
     https://thegraph.com/explorer/dashboard/.

  2. Type `cd land` to enter the subgraph.

  3. Run `yarn deploy` to deploy the subgraph to
     https://thegraph.com/explorer/subgraph/jannis/decentraland-land.

Make sure to visit the documentation on https://thegraph.com/docs/ for further information.

If an ABI cannot be found on Etherscan, this form asks for a local ABI file path:

$ graph init --from-contract 0xF87E31492Faf9A91B02Ee0dEAAd50d51d56D5d4f jannis/decentraland-land
✔ Subgraph name · jannis/decentraland-land
✔ Directory to create the subgraph in · land-2
✔ Ethereum network · mainnet
✔ Contract address · 0xF87E31492Faf9A91B02Ee0dEAAd50d51d56D5d4f
✖ Failed to fetch ABI from Etherscan: Unexpected token C in JSON at position 0
✔ ABI file (path) · /Users/jannis/Work/graphprotocol/subgraphs/decentraland/abis/LANDRegistry.json
———
  Generate subgraph from ABI
  Write subgraph to directory
✔ Create subgraph scaffold
✔ Initialize subgraph repository
⠋ Install dependencies with yarn
...

…erscan

Users can choose between these two modes. If they provide all the different values that each of the modes needs, the interactive form is bypassed, allowing the new `graph init` to be used in non-interactive environments such as CI.

The "Next steps:" instructions don't instruct me to run codegen, which is necessary before deploy.

Jannis · 2019-03-08T20:32:45Z

@leodasvacas That's because graph init runs it for you 😉

leoyvens · 2019-03-08T22:51:15Z

@Jannis ah nice, I got confused because of the /generated issue.

leoyvens

A bunch of small comments. Nice tests! It would be cool to also have a test for the generated contents.

+    })
+
+    if (inputs === undefined) {
+      process.exit(1)


Does inputs === undefined have a particular meaning? Should we print something here?

The inputs are undefined if the form is cancelled. I've added a comment.

Where's the comment?

Thanks @leodasvacas, I'll address the comments in the morning!

This behavior showed when using --from-example without an internet connection. Now it prints the actual error instead of silently failing.

Jannis · 2019-03-14T12:58:01Z

@leodasvacas I've fixed a few things, added a few comments and tried to address with comments with replies. Let me know what you think.

+          subgraphName,
+      },
+      dependencies: {
+        '@graphprotocol/graph-cli': '0.7.2',


We'll need to be careful to remember to update this, at least on breaking changes.

Indeed. I have an idea: How about we take the package version and put it in here? Then we're always up to date.

If that's possible that would be great.
