As a result of using absolute imports, your import statements are shortened by using packages. はじめに どーも!エンジニアのakiraです。 最近プロトタイプの開発が進み、バックエンド・フロントエンド・デスクトップアプリでコードを一部シェアしたいというケースに遭遇しました。 そこでhiroakiと相談しながら下記のような感じのフォル Help us understand the problem. This value is usually the same name as your package’s main entry point, in this case, index: From here, populate the package with your module’s exports, including its functions and types, and finally build it. One workspace can depend on another workspace simply by defining dependencies in the respected package.json file, just like you would with any other dependency: Once your configuration is complete, simply run yarn install from the root directory, and all your packages will be up to date, and ready to run. TypeScript: ^3.0.0 supports project references. Let's check if a service worker still exists or not. If you are running a previous version of the package, firstly upgrade the global command-line utility, then update your projects react-scripts package and its dependencies: Note: CRA version 3 does have breaking changes from the previous version. The issue with NodeJS projects is that there is no means for the compiled Javascript code to recognise Typescript path aliases. $ cd nextjs-typescript-yarn-workspaces $ yarn install $ yarn workspace @project/web-app dev Renaming for your project I named the example workspace packages @project/components and @project/web-app . Where projects require multiple packages, yarn workspaces can be leveraged, and used in conjunction with Lerna. How to build TypeScript mono-repo project Tools yarn: NPM client. Now, within tsconfig.json, we need to ensure that a definition file is generated at compile time, and ensure that a build directory is present: The declaration property declares that we wish to generate a .d.ts file when the project is compiled. Path aliases on the other hand could work very well with smaller projects, and also utilise in-house packages for re-usable components. Now we have the shared module, let’s enable yarn workspaces. In this case we have defined every folder under the packages/ directory to be a workspace. Yarn workspaces is commonly used in conjunction with Lerna, a tool specifically used for multi-package projects. To do that, we have to add the following line in the package.json. To extend the capabilities of the monorepo, we have dedicated tools, the most popular of which is Lerna. This type of project is called a Monorepo. TypeScript Project References は、tsconfig.json同士の依存関係を定義することで、効率的なビルドが可能になる仕組みです。. yarn workspace packageB remove packageA yarn workspaces remove lodash yarn remove -W -D typescript 3.1.4 项目构建 普通项目:建立一个build的npm script,使用yarn build即可完成项目构建 By following users and tags, you can catch up information on technical fields that you are interested in as a whole, By "stocking" the articles you like, you can search right away. The Yarn workspaces aim to make working with monorepos easy, solving one of the main use cases for yarn link in a more declarative way. Like package.json, we are providing the package directories, this time with the packages property. yarn publish --registry 'http://your-registry', How to Create a Progressive Web App with Vue.js, The Best JavaScript Audio Libraries for Manipulating Sound, The Other Side of React Native — Limitations & Opportunities of React Native, Building an Abstraction for React Internationalization Messages, They provide simplified paths to directories, allowing them to act as shortcuts to packages and other resources used throughout your project, They vastly decrease the use of relative import statements and the amount of, Common UX components that could be generic, Styling boilerplate such as page layout, text styling and default styles, Common form validations that may be specific to your needs, API handlers and other wrappers to handle external services, Any emerging design patterns in your app that can be templated, Each package is housed in a containing folder, which are commonly named identically to the. In fact, Lerna is still proving to be a vital tool for the Javascript community, currently on over 430k weekly downloads at the time of this writing. Now run npm publish to publish the package. Why not register and get more from Qiita? makes With yarn workspaces, all package dependencies are installed in one command — yarn install — from the root package. Support is being worked on, the progress of which is still an open issue. What we end up with is something like the following: In this example, the apps package will embed the three sub-sections that will comprise the entire app, with each of those utilising the components from the ui- packages. Integrating Lerna into a project just requires the installation of the package, and addition of a small configuration file: The configuration, lerna.json, is typically saved next to package.json: Note that we are specifying the npmClient to be yarn, and that useWorkspaces is set to true, so Lerna knows to implement Yarn Workspace features instead of its native implementation. 座右の銘は「なければ作ればいいじゃない。」. This tool convert lerna/npm/yarn workspaces to TypeScript's Project References. These packages will need to be housed within a main project repository; a repository that brings them all together. Lerna: Multiple packages management tool. if one package requires a different version of a dependency than another package, then it will be saved at that package level. Note: Deep diving into Lerna is out the scope of this article, but I will plug future articles here to expand on what we have introduced in this talk. Paths can be easily implemented in Node and Angular projects, but are currently lacking support with Create React App — although support is on the roadmap. Let’s assume these I love using React and NestJs together — it’s a killer typescript stack; and yarn workspaces is the glue that helps bind the common components, maximise reusability and … In summary: The solutions documented here may not all be suited for one particular project; it is instead advised to adopt them where they make sense. Check out all breaking changes here before upgrading. Typescript paths, also known as path aliases, allow us to define custom paths to a module, simplifying import statements. lerna/yarn/npm workspacesとTypeScript Project Referencesの設定を同期するツール. Just register service worker, "./src/{client,server}/src/**/*. monorepo環境で、yarn workspace を使って、create-react-app --typescript した client ワークスペースと、prisma2 で作成した server ワークスペースを共存させる手順のメモです。Lint, Prettier, Huskyの設定も行います。, 手元で同様の手順を踏んだリポジトリを、GitHub上に公開していますので、併せてご参照ください。, https://github.com/suzukalight/monorepo-react-prisma2, https://yarnpkg.com/lang/ja/docs/workspaces/, デフォルトで利用できるパッケージのアーキテクチャを設定する新しい方法です。ワークスペースにより複数のパッケージを設定する際に、 yarn install を一度実行するだけで、それらの全てが単一のパスにインストールされるようになります。, 1つのプロジェクトを立ち上げるとき、クライアント・サーバ・共通ロジック・Lambda・デザインシステム・LPなどの様々なサブプロジェクトが必要になることは多いと思います。これらを1つのリポジトリで扱えるようにする考え方が monorepo であり、それを実現する手段がワークスペースとなります。, monorepo環境の管理には、現在においては Lerna などが方法として存在しますが、ワークスペースはより低レベルでプリミティブな、内部依存関係の解決に特化した仕組みを提供してくれるものです。, yarn workspace で monorepo環境を構築する場合は、package.jsonに private: true と workspaces: {...} の2つを記述することになっています。, create-react-app で TypeScript の環境を作成します。(ejectは使用しません);, 個別のワークスペースでのみ使用するnpmモジュールをインストールする場合は、yarn workspace [ws-name] add コマンドを使用します。, ここでは、client側でしか使わないようなパッケージのインストールを行うために、yarn workspace client add コマンドを使用してみます;, 個別のワークスペースに記述したnpmスクリプトは、yarn workspace [ws-name] [script-name] コマンドで起動することができます。, この仕組みを利用して、ルートのpackage.jsonに、clientのdev-server起動コマンドを追加します;, 今回は手軽にGraphQLサーバを立てられる Prisma2 と graphql-yoga を利用して、簡単な手順でサーバを構築しています。, Prisma2 の CLI が未インストールの場合は、それもインストールしてください;, prisma2 は、2019年末のリリースに向けて、絶賛開発中です。そのため Breaking Changes が常に発生しており、執筆時点の preview-9.1 では PhotonJS のサンプルが正常に起動しませんでした。このため、バージョンを固定してインストールしています。, PhotonJS のサンプル から、5つのファイルをコピーし、初期環境としました;, package.json に dependencies などを追加していきます。このように yarn workspace [ws-name] add を通さず、直接package.jsonを書き換えてもOKです。, 変更したpackaje.jsonに基づいて、ワークスペースのnpmパッケージをインストールします;, コードの健全性を高めるために、すべてのワークスペースで、LintやPrettierを実行します。すべてのワークスペースで行うため、これらを共用モジュールとしてインストールします。, コーディングルールについては、各ワークスペースごとに個別の設定を行いたい場合は、各々のワークスペースに配置します。そうでないものについては、ルートディレクトリに配置します。, Lint+Prettier を行うスクリプトを、ルートのpackage.jsonに記述しておきます;, .prettierrc, .eslintrc.json, tsconfig.json を追加していきます。, tsconfig.json は client と server で異なります。いずれもすでに作成済みのものをそのまま利用します。, ルートディレクトリの tsconfig.json には、共通設定を置くのですが、ここは無指定とします(配置しないと lint 時にエラーが出たため、ダミーとして配置しています);, client 側は、create-react-app が提供しているファイルをそのまま利用します。React を意識した設定です;, server 側は、Prisma2 が提供しているファイルをそのまま利用します。ts-node を意識した設定です;, これとは別に、client側のlint設定に、React関係のプラグイン設定を追加し、配置しました;, これでクライアント・サーバ両方のLint+Prettierが実行できるようになりました。早速実行してみます;, もし「pluginが読み取れない」系のエラーが発生した場合は、@typescript-eslint/eslint-plugin @typescript-eslint/parser のバージョンを 1.3 にダウングレードしてみると良いかもしれません。, エラーが出ている部分を修正します。create-react-appの自動生成部分なので、それを信じて握りつぶします…。, ステージされたファイルの diff を見てみると、Prettier によっていくつかのファイルが自動整形されているのがわかります。これで Lint+Prettier が成功していることが確認できたと思います。, クライアント・サーバどちらのファイルがコミットされても、huskyによって自動的に Lint+Prettier が行われ、不健全なファイルがコミットされないように設定します;, package.json に husky と lint-staged の設定を追加します;, lintの通らないファイルがコミットに失敗するかをテストします。App.tsxの7行目に <> だけを追加してみます;, Prettier によって自動整形される例もテストします。さきほどのApp.tsxの <> を空行に置き換えます;, コミットしてみると、空行が取り除かれた状態でファイルが保存され、コミットされていることが確認できたと思います。これで成功です!, フロントエンドエンジニア (RELATIONS株式会社) / 一口馬主(キャロット) / Workspaces are relatively straight forward to set up with some initial boilerplate which you want to organize them,!
