NestJS をシンプルに初期構築から試す(その1nest cliを使いプロジェクト初期化)

Last updated at Posted at 2023-08-27

はじめに

記載する予定の内容です

GitHubリポジトリ

記事 ブランチ 内容
その1 feature/example-step1 nest cli
その2 feature/example-step2-sls use serverless framework, sls deploy

将来、1つのdevelop ブランチ にしてしまうかもしれません

最低限の準備

  • Node.js 18 が動く環境であること(v18.16.0を利用)
  • NestJS v10
  • Serverless Framework v3
  • なお、npm では ライブラリを Globalインストールをするため、コンテナ等の環境が好ましい

Node バージョン

$ node -v
v18.16.0

NestJS CLIをインストール

npm i -g @nestjs/cli
$ npm i -g @nestjs/cli

added 263 packages in 14s

44 packages are looking for funding
  run `npm fund` for details
$ nest -v
10.1.12

Serverless Frameworkをインストール

npm i -g serverless
$ npm i -g serverless
npm WARN deprecated querystring@0.2.0: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.
npm WARN deprecated querystring@0.2.1: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.
npm WARN deprecated querystring@0.2.0: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.
npm WARN deprecated superagent@7.1.6: Please downgrade to v7.1.5 if you need IE/ActiveXObject support OR upgrade to v8.0.0 as we no longer support IE and published an incorrect patch version (see https://github.com/visionmedia/superagent/issues/1731)
