A fully decentralized videos platform (youtube clone), ready to be deployed on MATIC network.
- TheGraph (GraphQL) as indexer
- Apollo client (to connect to theGraph)
- Mumbai (MATIC testnet)
- Next.js
- Tailwind
- plyr-react
- ... and many other
Instead of querying the blockchain every single time someone will access to the video, we will leverage a blockchain explorer called "theGraph". The first step is to create an account on it from here. Then create a "Subgraph".
Create a account on Infura, and create a new IPFS project. Don't forget to create a dedicated gateway subdomain in order to reach your documents from internet (from "manage key")
Install metamask Switch your network to mumbai :
| param | value |
|---|---|
| Network Name | Mumbai Testnet |
| New RPC URL | https://rpc-mumbai.maticvigil.com/ |
| Chain ID | 80001 |
| Currency Symbol | MATIC |
| Block Explorer URL | https://polygonscan.com/ |
and get some MATIC token from the official faucet : https://faucet.polygon.technology/
Your wallet private key will be needed to create the contract through hardhat - create a .env file that contains your private key:
# WARNING ::: NEVER, NEVER USE YOUR REAL WALLET PRIVATE KEY !!!! AND NEVER PUSH THIS FILE TO GITHUB !!!!
touch .env
echo "PRIVATE_KEY='xxx'" > .env
And install all the needed package with npm i.
Build & deploy are managed by hardhat. Code is already build so you just need to deploy it with the command below :
npx hardhat run scripts/deploy.js --network mumbai
>> YouTube deployed to: 0x6fA85CFb3b8714D00Cc2f198826CFEa5003E0Fba
Don't forget to store temporary the contract adress displayed in the console
For the "theGraph" explorer, you will have to rebuild with your own contract address:
npm install -g @graphprotocol/graph-cli
graph init
Make sure to input your contract address, name, and ABI.
Then generate the code for your graph and deploy it :
cd indexer
yarn codegen
yarn build
yarn deploy
It should work out of the box. Just add a .env.local with variables below :
NEXT_PUBLIC_VIDEO_PLATFORM_CONTRACT_ADRESS="your-contract-address"
NEXT_PUBLIC_SUBGRAPH_URL="your-subgraph-url"
NEXT_PUBLIC_INFURA_IPFS_PROJECT_ID="your-infura-ipfs-project"
NEXT_PUBLIC_INFURA_IPFS_PROJECT_SECRET="your-infura-ipfs-project-secret"
NEXT_PUBLIC_INFURA_IPFS_PRIVATE_GATEWAY="your-private-gateway-url-for-infura-ipfs"
For infura IPFS, Private gateway is now mandatory. And please be careful with the max limit for free-tier !
