The Graph application develops The MAC10 / Certos8 environment configuration

Based on the background of the team’s development of The Graph and its application of Subgraph, this paper introduces the construction of its environment: the offline developed machine is relatively complex, so the MAC machine is taken as an example to explain the step-by-step configuration; the online environment is relatively clean but lacks auxiliary software, so it needs to be deployed from scratch, so readers can read it as needed.

The Graph development environment is set up

Ganache deployment

In addition to the official documentation on local deployment, there is also this documentation on local deployment

NPM/Yarn installs truffle ganache-cli globally

$ npm install -g truffle ganache-cli

Pull Graph – Node (complex environment history at this level)

Download https://download.docker.com/m… , install into the APP, run and enter the password, the command line is available.

Everything looks fine, but subsequent installments can cause various problems, depending on the hardware and software environment on your machine, but both need to be properly handled.

$ brew install jq
$ docker -v

Doing the brew install install updates, filling holes see the brew upgrade installation error to solve the brew upgrade legacy MAC update component. Docker version 20.10.5, build 55c4c88 is OK. Graph – node node

$ git clone https://github.com/graphprotocol/graph-node/

The common human inaccessible areas such as git resource agent and mirror pit Sometimes repeatedly try it in the past, the past work is appreciated and backup some resources that have the force majeure can take these files in the future copy/paste (or directly use your colleague’s clean environment for local file, go back to solve the problem of your environment)

Configure to launch The Graph

$ cd graph-node/docker
$ ./setup.sh #write the host IP address into docker-compose.yml.
$ docker-compose up #Start a local Graph Node that will connect to Ganache on your host

Client Graphprotocol/Graph – CLI installation

$ npm install -g @graphprotocol/graph-cli
$ graph init --from-example moluoping/mark-cion 
 #graph init --from-example <GITHUB_USERNAME>/<SUBGRAPH_NAME> [<DIRECTORY>]

Yarn produced by the function of the lock file lock depends on package version, also locked source url can’t solve with mirror: backup the lock, use NPM down all packages (taobao mirror is not complete, using official http://registry.npmjs.org/) version (depend on) resource agent and mirror pit

Above are the examples of producing contracts and subgraphs

You can also generate a Subgraph project directly from the Container Contract Wizard:

$ graph init --from-contract 0x1e1215caD01aD7192832e0DACfA930Caf0132b43  --network mainnet --abi markdemo4.json moluoping/markdemo4

The monitor contract is configured by the contract ID

$ sed -i -e 's/0x2E645469f354BB4F5c8a05B3b30A929361cf77eC/0x71e11bC372507d508E05f65c096d32F1eF62Cdf7/g'     subgraph.yaml

Make a silly mistake here, and the second contract is really valid, But the next instruction to achieve effect sed – I – e ‘s / 0 x2e645469f354bb4f5c8a05b3b30a929361cf77ec / 0 x0a994866b43562c083c81e1b4ad6145214f56c56 / g’ Subgraph.

Because the first command has replaced the text

We are not proxying, we are on the way to mirroring, and sometimes git and yarn still have synchronization errors. This can be repeated as follows

Solution a: Replace the file Find/Users/gaoxiaoqing/Library/Caches/Homebrew/downloads/found 66 ff350c21fce7c264e33e3cff6f4995978ac401d5e5047c0ee8dd17e3493a 53 – m4-1.4.18. Mojave. Bottle. 1. Tar.

Scheme B: Replace Homebrew-bottles

BREW consists of four pieces

Homebrew	Source code repository
homebrew-core	Homebrew core source
homebrew-cask	Provide MacOS applications and large binaries installation
homebrew-bottles	Precompiled binary software packages

You can also change the image if you use it

Use the next section AliCloud Image to accelerate the solution

Ali cloud mirror acceleration

https://help.aliyun.com/docum…

To use Docker, you need to first download an official image, such as MySQL and WordPress. However, due to network reasons, it may take a long time to download a Docker official image, or even the download fails. To this end, ACR, AliCloud container mirroring service, provides an official mirroring site to accelerate the download of official images. Mirror Accelerator is a service for individual developers. It is limited to individual development scenarios and does not allow re-packaging or commercial use.

# sudo mkdir -p /etc/docker
# sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://de43k63h.mirror.aliyuncs.com"]
}
EOF
# sudo systemctl daemon-reload
# sudo systemctl restart docker

https://de43k63h.mirror.aliyu… Replace it with your mirror: For the address of the accelerator, after you log in to the container mirror service console, select the mirror tool > mirror accelerator in the left navigation bar. The mirror accelerator page will display the address assigned to you independently.

Continue with the./setup.sh setting to track the IP address
