```

### Install

```bash
npm i
```

### Start

First, move you abi file to abi folder,and then run

```bash
npm start {abipath} {name} {isHardhat}
```

> **note**: this name is config name and file name

Secord,set config 

```
module.exports = {
	privateKey:"", // this config is your privateKey 
	HTTP_PROVIDER:"", // this config is node with chain
	{name}:"" // this config is Contract address
}
```

Third, Run serve

```bash
npm run serve
```

now,start a journey

### Question

#### How do I know the API path

Go to the `app. js` , Look at the built API, and the parameters are exactly the same as the contract

#### How do I change the port

Go to the `app.js` , change the flowing code

```
app.listen(5000) // 5000 is port
console.log("Service is open,Port 5000")
```

the changed code

```
app.listen({the port you need})
console.log("Service is open,Port {the port you need}")
```
