node-复制文件

const path = require("path");
const fs = require("fs");
// 获取目录下的所有文件名
let fileNameList = fs.readdirSync(path.resolve(__dirname, "./template"))
console.log(fileNameList)

// 文件复制
// 1. 管道指引流的方式复制文件
let indexFile = fs.createReadStream(path.resolve(__dirname, "./template/index.js"));
let indexTo = fs.createWriteStream(path.resolve(process.cwd(), "./to/index.js"))
indexFile.pipe(indexTo)

// 2. 原生的readFile(Sync)和writeFile(Sync) ，参数为path和编码格式(或者内容)
// 区分同步和异步
let contentSync = fs.readFileSync(path.resolve(__dirname, "./template/render.vue"), "utf-8")
fs.writeFileSync(path.resolve(process.cwd(), "./to/render.vue"), contentSync)
fs.readFile(path.resolve(__dirname, "./template/render.vue"), "utf-8", function (err, data) {
  console.log(err, data)
  fs.writeFileSync(path.resolve(process.cwd(), "./to/render.vue"), data, function (error) {
    console.log(error)
  })
})

// 3. copyFile(formPath, toPath), 或者copyFileSync
copyFileSync(path.resolve(__dirname, "./template/render.vue"), path.resolve(__dirname, "./to/render.vue"))
fs.copyFile(path.resolve(__dirname, "./template/render.vue"), path.resolve(__dirname, "./to/render.vue"), 0, () => {
  console.log("复制完成")
})
