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>
This app requires node.js (tested on v12+)
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
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.
pnpm setup
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
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
- docker-compose: running the ethereum node, ipfs node and subgraph node.
- common-lib: watching for changes and recompiling to js.
- web app: watching for changes. Hot Module Replacement enabled. (will reload on common-lib changes)
- contracts: watching for changes. For every code changes, contract are redeployed, with proxies keeping their addresses.
- 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
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>]
This will build a static version of the web app for the specified network.
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
.
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.
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 useMNEMONIC_<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.
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 (VITE_THE_GRAPH_HTTP, VITE_CHAIN_ID). You can either set them in fleek dashboard or set them in .fleek.json
