Automation

Right, let’s talk about pre-commit hooks. You’re about to automate the most annoying, nagging part of your workflow: catching stupid mistakes before they become a commit message you have to explain to your team. This isn’t just about linting; it’s about professional-grade hygiene. We’re going to use Husky to easily manage Git hooks and lint-staged to be brutally efficient about it. Why run linting on your entire 10,000-file project when you only changed two? That’s like washing your entire car because a bird targeted your windshield. lint-staged is your detail-oriented friend with the Windex and a rag.

Right, so you’ve got your tests passing and your linter is happy. Now comes the fun part: actually shipping this thing to users without causing a collective gasp on Twitter. Doing this manually is a recipe for human error, forgotten steps, and a special kind of developer despair. We automate. The goal is to take your merged code and, with zero human intervention, bump the version number, generate changelogs, and publish to your package registry (be it npm, GitHub Packages, etc.).

Right, let’s talk about keeping your TypeScript project from turning into a digital museum. You know the feeling: you npm install on a six-month-old project and it’s like unearthing a time capsule. Suddenly, you’re wrestling with deprecated APIs, incompatible @types, and a node_modules folder that sighs with the weight of history. We’re not doing that. We’re going to automate this tedancy away with either Renovate or Dependabot. Think of them as your highly opinionated, slightly obsessive-compulsive library assistants. Their job is to constantly pester you with little pull requests saying, “Hey, genius, lodash is 47 versions behind. Maybe we should do something about that?”

Right, let’s talk about one of the most soul-crushing experiences in modern software development: watching your CI runner install the same node_modules directory for the 10,000th time. It’s a special kind of agony, watching those dependency trees resolve at a glacial pace, burning through your precious CI minutes and your team’s will to live. We’re not here to suffer; we’re here to automate. And a key part of automation is not doing work you’ve already done. That’s where caching comes in.

Right, let’s get your TypeScript project off your local machine and into the cold, unforgiving light of automation. You’re not just writing code; you’re building a system. And a system that only works on your machine is a system that’s one npm install away from collapse. We’re going to use GitHub Actions because it’s right there, it’s powerful, and frankly, it’s a lot less fuss than some alternatives for a project living on GitHub.

Right, so you’ve got your TypeScript compiling. The code runs. You’re feeling pretty good. But let me ask you a question you didn’t want to hear: are you sure you don’t have any type errors? I mean, really sure? If you’re just running tsc to emit JavaScript, you’re living on a prayer. That command will happily spit out .js files even if your types are a complete dumpster fire, as long as the syntax is vaguely correct. It’s the equivalent of saying “Well, the engine fell out, but look, the radio still works!”
