Subgraph in The Graph for KEEP NETWORK

Use docs https://thegraph.com/docs

The first step is to access Graph Explorer https://thegraph.com/explorer/. If you still don’t have an account you can signup with Github. After that, you go to your Dashboard and you will see a nice page with four clear steps: a. Create; b. Install; c. Init; and d. Deploy.

1. Register an account on github.
2. Create a repository.

a. Create undeployed subgraph

Next, you need to perform 3 parameters: Installation, initialization, and deployment.

npm install -g @graphprotocol/graph-cli
yarn global add @graphprotocol/graph-cli

We will do this using the terminal on MAC OS

GUIDE to install yarn, nvm (node) on macOS
1. Install Homebrew

/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
2. Prepare before setup (cleanup)
brew uninstall — force yarn node npm # remove previously installed node, npm, yarn
brew cleanup # clean all broken symlinks and “waste” (not really required as of homebrew 2019)
brew update # always good to have the latest
3.Install yarn via homebrew
brew install yarn
4.Install nvm
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.35.3/install.sh | bash
Help error setup nvm for macOSX:
create .bash_profile file
cd ~
touch .bash_profile
#open the file you just created
open .bash_profile
#paste the following code inside the file
export NVM_DIR=~/.nvm
source ~/.nvm/nvm.sh
#run the source command after saving
source .bash_profile
#then enter the command
nvm — version
5.Install node latest lts
nvm install lts/erbium
6.Set nvm to use latest LTS as default for new bash sessions
echo “lts/erbium” > .nvmrc # default to the latest LTS version
nvm alias default lts/erbium

RESTART all terminals => you’re done ;-)

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 keepsubgraphs to enter the subgraph.

3. Run yarn deploy to deploy the subgraph to
https://thegraph.com/explorer/subgraph/honeynastu/keep.
