emulator

Vela 模拟器 SDK

模拟器的介绍可参考开发帮助文档里的「模拟器」章节

目录结构

目录	描述
avd	模拟器的AVD，配置统一放置$HOME/.vela/vvd 目录下
instance	模拟器实例，不同的Vela镜像版本会使用不同的instance，通过findInstance确定
static	创建AVD时需要用到的静态资源，常量配置文件
typing	接口定义
utils	工具函数

安装

npm install @aiot/emulator

使用

创建 VVD

import os from 'os'
import path from 'path'
import { IAvdArchType, VelaAvdCls, VelaImageType } from '@aiot/emulator'

const sdkHome = path.resolve(os.homedir(), '.export_dev')
const velaAvdCls = new VelaAvdCls({ sdkHome })

/** 创建一个 466 × 466 带 miwear 的模拟器 */
export async function createVVd() {
  velaAvdCls.createVvd({
    avdName: 'test',
    avdArch: IAvdArchType.arm64,
    avdHeight: '466',
    avdWidth: '466',
    imageType: VelaImageType.REL
  })
}

启动 VVD

import os from 'os'
import path from 'path'
import { IAvdArchType, VelaAvdCls, VelaImageType } from '../src'

const sdkHome = path.resolve(os.homedir(), '.export_dev')
const velaAvdCls = new VelaAvdCls({ sdkHome })

export async function startVvd(vvdName: string) {
  velaAvdCls.startVvd({
    avdName: vvdName
  })
}

初始化环境

import os from 'os'
import path from 'path'
import { VelaAvdCls } from '@aiot/emulator'

async function main() {
  const sdkHome = path.resolve(os.homedir(), '.export_dev')
  const velaAvdCls = new VelaAvdCls({ sdkHome })

  const downloder = await velaAvdCls.downloadSDK({
    force: true,
    cliProgress: false,
    parallelDownloads: 6
  })

  downloder.on('progress', (progress) => {
    console.log(
      `progress: ${progress.formattedSpeed} ${progress.formattedPercentage} ${progress.formatTotal} ${progress.formatTimeLeft}`
    )
  })

  await downloder.downlodPromise

  console.log('download success')
}

main()
