Create EVM App

===============

Quickly build apps backed by the EVM-based blockchain

Prerequisites

Make sure you have a current version of Node.js installed – we are targeting versions 16+.

Read about other prerequisites in our docs.

Dev Testing

To test the tool on the local dev:

pnpm install && pnpm start

To install the tool globally on the local dev:

npm i -g

Then, the create-evm-app binary will available with npx command.

Getting Started

To create a new EVM fullstack dapp run this and follow interactive prompts:

npx create-evm-app

Follow the instructions in the README.md in the project you just created! 🚀

You can create contracts written in Solidity with:

• Hardhat
• Foundry

You can create a frontend template with:

• NextJS
• Vite

Using CLI arguments to run create-evm-app

This CLI supports arguments to skip interactive prompts:

npx create-evm-app
  <project-name>
  --contract hardhat|foundry|none
  --frontend nextjs|vite|none
  --subgraph the-graph|none
  --install

Use --install to automatically install dependencies from all package.json files.

When using arguments, all arguments are required, except for --install.

Contributing to create-evm-app

To make changes to create-evm-app itself:

• clone the repository
• in your terminal, enter one of the folders inside templates, such as templates/contracts/hardhat
• now you can run npm install to install dependencies and npm run dev to run the local development server, just like you can in a new app created with create-evm-app

About commit messages

create-evm-app uses semantic versioning and auto-generates nice release notes & a changelog all based off of the commits. We do this by enforcing Conventional Commits. In general the pattern mostly looks like this:

type(scope?): subject  #scope is optional; multiple scopes are supported (current delimiter options: "/", "\" and ",")

Real world examples can look like this:

chore: run tests with GitHub Actions

fix(server): send cors headers

feat(blog): add comment section

If your change should show up in release notes as a feature, use feat:. If it should show up as a fix, use fix:. Otherwise, you probably want refactor: or chore:. More info

Deploy create-evm-app

If you want to deploy a new version, you will need two prerequisites:

1. Get publish-access to the NPM package
2. Get write-access to the GitHub repository
3. Obtain a personal access token (it only needs the "repo" scope).
4. Make sure the token is available as an environment variable called GITHUB_TOKEN

Then run one script:

pnpm release

Or just release-it
