hot-chain-svg

A toolkit for building on-chain SVG projects.

Demo

Getting started

Feel free to clone the repo and tune it for your own needs. The codebase tries to be self-contained and only depends on NodeJS. You can integrate it with Hardhat and Foundry-based projects.

$ git clone https://github.com/w1nt3r-eth/hot-chain-svg
$ cd hot-chain-svg
$ yarn

Hot Reloading

$ yarn start

Open the URL (http://localhost:9901). Every time you change Renderer.sol, the webpage will automatically refresh. Use Chrome DevTools to inspect the page.

Visual QA

$ yarn qa

This will render 256 tokens into a temporary folder. It will also check the resulting SVG for syntax errors. Open the folder and view the resulting files. Feel free to edit src/qa.js.

React-inspired API

You'll notice there's SVG.sol inside the contracts folder. The idea is to provide a React-inspired API, tailored to SVG graphics. It's not complete. You don't have to use it to benefit from hot reloading and visual QA script.

Under the hood

hot-chain-svg uses solc to compile Solidity files. Then, it deploys it to a local VM instance (powered by @ethereumjs/vm) and calls the example function. The resulting SVG image is served via the built-in HTTP server.

The tool also watches the files in contracts for changes. When it detects a change, it sends an event to the browser via EventSource subscription, which causes the page to reload.

If your project is using hot-chain-svg, you can add it to this list by minting a free NFT. The NFTs are automatically synced with this README using a cron job on GitHub Actions.

You can also support the project by sending Ether when minting the NFT.

To mint

1. Open Hot Chain SVG on Etherscan
2. Inside "Contract" tab, select "Write Contract"
3. Connect your wallet
4. Choose mint function
   • payableAmount (ether) is the optional donation to send to the project. The card will be rendered differently depending on the amount (see below)
   • name is the project name as it will appear on the card
   • collection is the address on your contract that uses hot-chain-svg (you can use your own wallet address if you don't have a contract deployed)

Contributing

Check out GitHub issues and feel free to send a PR. The codebase tries to stick to vanilla JS and minimum dependencies, there are more interesting things in the world than fighting TypeScript and ES6 modules.
