升级到 10.x 后改动

官方 docs

升级到 10.x 后我们可以使用 swc 启动项目，swc 会使项目启动速度有很大提升。使用 swc 后我们需要做一些改动。

安装 SWC

pnpm i -D @swc/cli @swc/core

项目改动

"scripts": {
  "build": "nest build -b swc --type-check",
  "build": "nest build",
  "start:dev": "nest start -b swc --type-check --watch",
  "start:dev": "nest start --watch"
}

nest-cli.json 中添加

{
  "$schema": "https://json.schemastore.org/nest-cli",
  "collection": "@nestjs/schematics",
  "sourceRoot": "src",
  "compilerOptions": {
    "deleteOutDir": true,
    "builder": "swc",
    "typeCheck": true
  }
}
