Remix + Express + TS

如何將 TypeScript 新增至 Remix + Express 項目

你好！在本文中，我將指導您將 TypeScript 新增至 Remix + Express 樣板專案的步驟。在本教學結束時，您將擁有一個使用 Express 和 Typescript 運行的功能齊全的 Remix 應用程式。您可以在這裡找到最終代碼。

第 1 步：克隆官方 Express Starter

首先，讓我們先從複製官方 Remix Express 入門範本開始：

npx create-remix@latest --template remix-run/remix/templates/express

登入後複製

第 2 步：新增所需的依賴項

接下來，安裝 TypeScript 支援所需的附加相依性：

npm install -D esbuild tsx

登入後複製

步驟 3：建立 TypeScript 伺服器文件

刪除現有的 server.js 文件，並建立一個名為 server/index.ts 的新文件。

然後，將以下程式碼複製並貼上到 server/index.ts 中：

// server/index.ts
import { createRequestHandler } from "@remix-run/express";
import { type ServerBuild } from "@remix-run/node";
import compression from "compression";
import express from "express";
import morgan from "morgan";

const viteDevServer =
  process.env.NODE_ENV === "production"
    ? undefined
    : await import("vite").then((vite) =>
        vite.createServer({
          server: { middlewareMode: true },
        })
      );

const app = express();

app.use(compression());

// http://expressjs.com/en/advanced/best-practice-security.html#at-a-minimum-disable-x-powered-by-header
app.disable("x-powered-by");

// handle asset requests
if (viteDevServer) {
  app.use(viteDevServer.middlewares);
} else {
  // Vite fingerprints its assets so we can cache forever.
  app.use(
    "/assets",
    express.static("build/client/assets", { immutable: true, maxAge: "1y" })
  );
}

// Everything else (like favicon.ico) is cached for an hour. You may want to be
// more aggressive with this caching.
app.use(express.static("build/client", { maxAge: "1h" }));

app.use(morgan("tiny"));

async function getBuild() {
  try {
    const build = viteDevServer
      ? await viteDevServer.ssrLoadModule("virtual:remix/server-build")
      : // @ts-expect-error - the file might not exist yet but it will
        // eslint-disable-next-line import/no-unresolved
        await import("../build/server/remix.js");

    return { build: build as unknown as ServerBuild, error: null };
  } catch (error) {
    // Catch error and return null to make express happy and avoid an unrecoverable crash
    console.error("Error creating build:", error);
    return { error: error, build: null as unknown as ServerBuild };
  }
}
// handle SSR requests
app.all(
  "*",
  createRequestHandler({
    build: async () => {
      const { error, build } = await getBuild();
      if (error) {
        throw error;
      }
      return build;
    },
  })
);

const port = process.env.PORT || 3000;
app.listen(port, () =>
  console.log(`Express server listening at http://localhost:${port}`)
);

第四步：更新Vite配置

要在 Remix 完成建置後建置 Express 伺服器，請使用下列內容更新您的 vite.config.ts 檔案：

import { vitePlugin as remix } from "@remix-run/dev";
import { defineConfig } from "vite";
import tsconfigPaths from "vite-tsconfig-paths";
import esbuild from "esbuild";

export default defineConfig({
  plugins: [
    remix({
      future: {
        v3_fetcherPersist: true,
        v3_relativeSplatPath: true,
        v3_throwAbortReason: true,
      },
      serverBuildFile: 'remix.js',
      buildEnd: async () => {
        await esbuild.build({
          alias: { "~": "./app" },
          outfile: "build/server/index.js",
          entryPoints: ["server/index.ts"],
          external: ['./build/server/*'],
          platform: 'node',
          format: 'esm',
          packages: 'external',
          bundle: true,
          logLevel: 'info',
        }).catch((error: unknown) => {
          console.error('Error building server:', error);
          process.exit(1);
        });
      }
    }),
    tsconfigPaths(),
  ],
});

第 5 步：更新 NPM 腳本

現在，更新 package.json 中的啟動和開發腳本：

"scripts": {
  "build": "remix vite:build",
  "dev": "tsx server/index.ts",
  "lint": "eslint --ignore-path .gitignore --cache --cache-location ./node_modules/.cache/eslint .",
  "start": "cross-env NODE_ENV=production node ./build/server/index.js",
  "typecheck": "tsc"
}
