The status of Node.js 12 is now end-of-life. It’s the last version that didn’t have ES module support from the beginning. We have therefore reached an important milestone in Node’s support for ESM.

Convert loops, extract variables, and much more. With the P42 JavaScript Assistant.

New feature: --install-links locally installs file: dependencies (instead of symlinking them).

We're looking for a senior engineer to run our frontend team - joining a small, highly experienced, well-funded team at Parallel Markets to help build the future of portable financial identity. We're remote-first and work async, and we just raised a $7M Series A. No Jira, and (almost) no meetings!

Features:

• Use the npm run commands you already know
• Automatically run dependencies between npm scripts in parallel
• Watch any script and continuously re-run on changes
• Skip scripts that are already fresh
• Cache output locally and remotely on GitHub Actions for free
• Works with single packages, npm workspaces, and other monorepos

Script definitions look like this:

{
  "scripts": {
    "build": "wireit",
    "bundle": "wireit"
  },
  "wireit": {
    "build": {
      "command": "tsc",
      "files": ["src/**/*.ts", "tsconfig.json"],
      "output": ["lib/**"]
    },
    "bundle": {
      "command": "rollup -c",
      "dependencies": ["build"],
      "files": ["rollup.config.json"],
      "output": ["dist/bundle.js"]
    }
  }
}

Christoph Nakazawa walks us through the steps of building a JavaScript bundler:

• Efficiently search for all files on the file system
• Resolve the dependency graph
• Serialize the bundle
• Execute our bundle using a runtime
• Compile each file in parallel

Most internal tools are made of the same building blocks: tables, drop-downs, buttons, text inputs, etc. Rather than building a tool from scratch, Retool gives you a point, click, drag & drop interface that makes it simple to build internal UIs fast. But you're never limited by what's available out-of-the-box - you can customize anywhere using JavaScript. Join companies like Amazon, Doordash, and Brex and start building your internal tools in Retool.

ShadowRealm is a stage 3 ECMAScript proposal for dynamically evaluating code (think eval() but better).
