Jolly Roger

This is a template to build a decentralised applicaiton using ethereum, hardhat, svelte and thegraph

to make an app out of it, execute the following

npx degit wighawag/jolly-roger <your-app-folder>

There also more templates available in branches:



App Setup

requirements :

This app requires node.js (tested on v12+)

pnpm

This repo use pnpm for package management : https://pnpm.js.org

npx pnpm add -g pnpm

pnpm is used because it has the best mono-repo support which this project relies on. You might be able to switch to yarn but will most likely have to configure it to fix hoisting issues. If you decide to use yarn you ll have to remove the script "preinstall" that by default force the use of pnpm

docker and docker-compose

docker and docker-compose are used to setup the external services (an ethereum node, an ipfs node and a subgraph node)

If you prefer (or do not have access to docker/docker-compose) you can run them independently.

intall dependencies :

pnpm boot

This will set the app name (and change the files to reflect that) and then call pnpm install

You can also manually set the name yourself :

pnpm set-name [<new name>] && pnpm install

Development

The following command will start everything up.

pnpm start

This will run each processes in their own terminal window/tab. Note that you might need configuration based on your system.

On linux it uses xterm by default (so you need that installed).

On windows it use cmd.exe by default.

If you need some other terminal to execute the separate processes, you can configure it in .newsh.json.

This command will bring 5 shells up

  1. docker-compose: running the ethereum node, ipfs node and subgraph node.
  2. common-lib: watching for changes and recompiling to js.
  3. web app: watching for changes. Hot Module Replacement enabled. (will reload on common-lib changes)
  4. contracts: watching for changes. For every code changes, contract are redeployed, with proxies keeping their addresses.
  5. subgraph: watch for code or template changes and redeploy.

Once docker-compose is running, you can stop the other shells and restart them if needed via

pnpm dev

Alternatively you can call the following first : this will setup the external services only (ipfs, ethereum and graph nodes)

pnpm externals

and then run pnpm dev to bring up the rest in watch mode.

You can also always run them individually

full list of commands

Here is the list of npm scripts you can execute:

Some of them relies on ./_scripts.js to allow parameterizing it via command line argument (have a look inside if you need modifications)

pnpm prepare

As a standard lifecycle npm script, it is executed automatically upon install. It generate various config file for you, including vscode files.

pnpm setup

this will update name of the project (by default "jolly-roger") to be the name of the folder (See set-name command) and install the dependencies (pnpm install)

pnpm set-name [<new name>]

This will replace every instance of jolly-roger (or whatever name was set) to new name (if specified, otherwise it use the folder name) If your name is not unique and conflict with variable name, etc... this will not be safe to execute.

pnpm common:dev

This will compile the common-library and watch for changes.

pnpm common:build

This will compile the common library and terminate

pnpm contracts:dev

This will deploy the contract on localhost and watch for changes and recompile/redeploy when so.

pnpm contracts:deploy [<network>]

This will deploy the contract on the network specified.

If network is a live network, a mnemonic and url will be required. the following env need to be set:

  • MNEMONIC_<network name>
  • ETH_NODE_URI_<network name>

pnpm seed [<network>]

This will execute the contracts/scripts/seed.ts on the network specified

pnpm subgraph:dev

This will setup and deploy the subgraph on localhost and watch for changes.

pnpm subgraph:deploy [<network>]

This will deploy subgraph on the network specified. If network is a live network, the following env beed to be set:

  • THEGRAPH_TOKEN token giving you write access to thegraph.com service

pnpm web:dev [<network>]

This will spawn a vite dev server for the webapp, connected to the specified network

pnpm web:build [<network>] or pnpm build [<network>]

This will build a static version of the web app for the specified network.

If no network are specified it will fetch from the env variable NETWORK_NAME. If no such env variable is set, it will try to fetch the git's branch name.

pnpm web:serve

This will serve the static file as if on an ipfs gateway.

pnpm web:build:serve [<network>]

this both build and serve the web app.

pnpm web:deploy <network>

This build and deploy the web app on ipfs for the network specified.

You ll need the following env variables setup :

  • IPFS_DEPLOY_PINATA__API_KEY │
  • IPFS_DEPLOY_PINATA__SECRET_API_KEY



pnpm deploy [<network>]

This will deploy all (contracts, subgraph and web app). See below for more details.

If no network are specified it will fetch from the env variable NETWORK_NAME. If no such env variable is set, it will try to fetch the git's branch name.

pnpm deploy:noweb [<network>]

This will deploy all (contracts, subgraph) except web app. See below for more details.

If no network are specified it will fetch from the env variable NETWORK_NAME. If no such env variable is set, it will try to fetch the git's branch name.

pnpm stop

This stop the docker services running

pnpm externals This spawn docker services: an ethereum node, an IPFS node and a subgraph node

pnpm dev This assume external service run. It will spawn a web server, watch/build the common library, the web app, the contracts and the subgraph. It will also seed the contracts with some data.

pnpm start It will spawn everything needed to get started, external services, a web server, watch/build the common library, the web app, the contracts and the subgraph. It will also seed the contracts with some data.

env variables required for full deployment

You need to gather the following environment variables :

  • THEGRAPH_TOKEN=<graph token used to deploy the subgraph on thegraph.com>
  • INFURA_TOKEN=<infura token to talk to a network>
  • IPFS_DEPLOY_PINATA__API_KEY=<pinata api key>
  • IPFS_DEPLOY_PINATA__SECRET_API_KEY=<pinata secret key>
  • MNEMONIC=<mnemonic of the account that will deploy the contract> (you can also use MNEMONIC_<network name>)

Note that pinata is currently the default ipfs provider setup but ipfs-deploy, the tool used to deploy to ipfs support other providers, see : https://github.com/ipfs-shipyard/ipfs-deploy

For production and staging, you would need to set MENMONIC too in the respective .env.production and .env.staging files.

You can remove the env if you want to use the same as the one in .env

You'll also need to update the following for staging and production :

  • SUBGRAPH_NAME=<thegraph account name>/<subgraph name>
  • VITE_CHAIN_ID=<id of the chain where contracts lives>
  • VITE_THE_GRAPH_HTTP=https://api.thegraph.com/subgraphs/name/<thegraph account name>/<subgraph name>

you then need to ensure you have a subgraph already created on thegraph.com with that name: https://thegraph.com/explorer/dashboard

Furthermore, you need to ensure the values in web/application.json are to your liking. Similar for the the web/public/preview.png image that is used for open graph metadata. The application.json is also where you setup the ens name if any.

fleek github integration

For web:build you can also use fleek so that building and ipfs deployment is done automatically. The repo provide a .fleek.json file already setup for staging.

The only thing needed is setting up the environment variables. You can either set them in fleek dashboard or set them in .fleek.json

Note though that no environment variables might be needed, if you branch name is equal to the expected network name and you have got VITE_THE_GRAPH_HTTP set in the .env.<networkName>.default file.

Here are the env variable and their default:

  • NETWORK_NAME: mandatory but will default to the got branch name if a deployment folder is found
  • VITE_CHAIN_ID: will default to the chainId specificed in the contracts.json
  • VITE_ETH_NODE_URI: optional, if set, the app will have access to on-chain data through that node. Better not make your app depends on it.
  • VITE_THE_GRAPH_HTTP: This can be set up in the .env.<networkName>.default file

other git integrations

Vercal can be easily setup like fleek above. THe only thing needed currently is to set the following install command:

  • npx pnpm i

And like fleek you ll need to setup NETWORK_NAME env variable unless it is the same as the branch name.
