Vercel Deploy Script

readme.md

Vercel Deploy Script

This takes advantage of deployment hooks on Vercel. This simply removes the deploy file if it exists. Otherwise, it creates it. Then pushes it to the repository.

Usage

Add to your package.json

{
  "scripts": {
    "release": "node ./scripts/release.js"
  }
}

Afterwards you're good to go

npm run release

release.js

const fs = require("fs");
const path = require("path");
const { execSync } = require("child_process");

const root = path.resolve(__dirname, "..");
const deployFilePath = path.join(root, "deploy");

// This script automates the deployment process:
// 1. Checks if the current branch is 'main'
// 2. Creates or removes a 'deploy' file in the root directory
// 3. Commits all changes with the message "deploy"
// 4. Pushes the changes to the remote repository
// This script relies that on Vercel's deploy on push hook.

console.log("[deploy] Checking current branch...");
try {
  const currentBranch = execSync("git rev-parse --abbrev-ref HEAD", {
    encoding: "utf8",
    cwd: root,
  }).trim();
  if (currentBranch !== "main") {
    console.error(
      "[deploy] Warning: Current branch is not main. Current branch:",
      currentBranch,
    );
  }
  console.log("[deploy] Confirmed current branch is main");
} catch (error) {
  console.error("[deploy] Error checking git branch:", error.message);
  process.exit(1);
}

try {
  console.log("[deploy] Starting deployment process...");

  if (fs.existsSync(deployFilePath)) {
    fs.unlinkSync(deployFilePath);
  } else {
    fs.writeFileSync(deployFilePath, "");
  }

  console.log("[deploy] Committing...");

  // Run git commands
  execSync("git add .", { stdio: "inherit", cwd: root });
  execSync('git commit -m "deploy"', { stdio: "inherit", cwd: root });

  console.log("[deploy] Pushed.");
  execSync("git push", { stdio: "inherit", cwd: root });
} catch (error) {
  console.error("[deploy] Error triggering deployment:", error.message);
}
