Graph CLI​

✅ Deploy your subgraph using the CLI​

✅ Use the Graph CLI to complete the deployment​

Studio6

You can install the Graph CLI globally using the following command.

curl -LS https://cli.thegraph.com/install.sh | sudo sh

✅ Init your Subgraph​

This can be done in a separate folder of your choosing, since it will initiate a yarn package. You will need to fill in the required configuration during the initialization process.The Start Block - Can be found on Etherescan if needed so you don't have to index the entire previous blocks.

graph init --studio name_of_your_subgraph

It should looks something like this...

✅ Authenticate to Studio​

Grab your authentication string from Auth & Deploy on Subgraph Studio.

graph auth --studio auth_key_here

Success looks like this:

Deploy key set for https://api.studio.thegraph.com/deploy/

✅ Run codegen and build your subgraph​

You will need to change into the directory where the subgraph was created in the previous step.

cd sendmessage
graph codegen && graph build

Success will look something like the following!

✅ Deploy​

Now we are ready to deploy to the Studio

graph deploy --studio name_of_your_subgraph

Choose a version and fire away!

It might take up to 5 minutes for you subgraph to deploy to the studio. Once it has been deployed, you can check that is fully syncing and has no errors. A successful deploy will look like the following.
