# tevm-monorepo
Tevm is a JavaScript EVM client and a Solidity-to-TypeScript compiler.
## Features
✅ EVM simulations
✅ forking akin to [anvil --fork-url](https://github.com/foundry-rs/foundry/tree/master/crates/anvil)
✅ Solidity scripting akin to [foundry scripts](https://book.getfoundry.sh/tutorials/solidity-scripting)
✅ Compiles contracts in JavaScript via importing solidity files
✅ Extensions for usage with Viem, Ethers.js, Next.js, and Express.
✅ Compiles contracts in JavaScript via importing solidity files
🏗️ EVM Tracing (coming in upcoming release)
🏗️ React hook library
🏗️ First class vue and svelte support
Tevm runs in all environments
- [All modern browsers](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API#browser_compatibility)
- [Node.js >=18](https://nodejs.org/en)

## Code example
1. Write a solidity script `HelloWorld.s.sol`
```solidity
// SPDX-License-Identifier: MIT
pragma solidity >0.8.0;
contract HelloWorld {
function greet(string memory name) public pure returns (string memory) {
return string(abi.encodePacked("Hello ", name, "!"));
}
}
```
2. Import the solidity file into a JavaScript or TypeScript file. No need to compile it.
```typescript
import { HelloWorld } from './HelloWorld.sol'
console.log(HelloWorld.abi)
console.log(HelloWorld.bytecode)
```
3. Initialize a [Tevm memory client](./packages/memory-client/docs/functions/createMemoryClient.md) and execute your Script using the [`tevm.script`](./packages/actions-types/docs/type-aliases/ScriptHandler.md) action
```typescript
import { HelloWorld } from './HelloWorld.sol'
import { createMemoryClient } from 'tevm'
const client = createMemoryClient()
const result = await client.script(
HelloWorld.read.greet('World')
)
console.log(result.data) // Hello world!
```
This is just a small subset of what Tevm offers. See [docs](https://tevm.sh/) for more information.
