lesson-5_Deploy to localhost

Deploy​

✅ Create and ship our Subgraph​

Now we can open up a fourth window to finish setting up The Graph. 😅 In this forth window we will create our local subgraph!

Note: You will only need to do this once.

yarn local-create

You should see some output stating your Subgraph has been created along with a log output on your graph-node inside docker.

Next we will ship our subgraph! You will need to give your subgraph a version after executing this command.（e.g. 0.0.1）.

yarn local-ship

This command does the following all in one… 🚀🚀🚀

  • Copies the contracts ABI from the hardhat/deployments folder
  • Generates the networks.json file
  • Generates AssemblyScript types from the subgraph schema and the contract ABIs.
  • Compiles and checks the mapping functions.
  • … and deploy a local subgraph!

If you get an error ts-node you can install it with the following command

npm install -g ts-node

If your subgraph deployment was successful it will look something like this:

You should get a build completed output along with the address of your Subgraph endpoint.
