The Language Server Protocol (LSP) lets you write language smarts once and use them in every editor. You build one server that handles autocomplete, diagnostics, hover docs, and go-to-definition. Then you plug it into VS Code, Neovim, Helix, Emacs, or anything else that speaks LSP. This walkthrough shows how to build an LSP server in TypeScript for a custom .config file format, from setup through multi-editor support.

What the Language Server Protocol Actually Is

Before LSP, editor support for a language meant writing a separate plugin for every editor. Want Python support? Write a VS Code extension, an Emacs mode, a Vim plugin, a Sublime plugin. Each one redoes parsing, diagnostics, and completion from scratch. With N editors and M languages, that’s N*M plugins to maintain.

On February 26, 2026, Claude Code ran terraform destroy against a stale state file. It wiped 2.5 years of DataTalks.Club production data: the RDS database, VPC, ECS cluster, load balancers, and every automated snapshot. Four cascading failures, each one preventable, took down a platform serving 100,000 learners.

Alexey Grigorev runs DataTalks.Club , a data engineering school with over 100,000 learners. He lost 1,943,200 rows of homework, project entries, and leaderboard scores when Claude Code ran the command against his whole production stack. The database, the VPC, the ECS cluster, load balancers, bastion host, and every automated snapshot were gone in seconds.

Dagger lets you write CI/CD pipelines in Go, Python, or TypeScript instead of YAML. Your pipelines run inside containers, execute identically on your laptop and in CI, and get type-checked by your compiler or linter before they ever touch a remote runner. If you’ve spent hours pushing commits just to debug a GitHub Actions workflow, Dagger is the fix.

The core idea: pipeline steps are function calls in a real programming language. Each function call builds a directed acyclic graph (DAG) of container operations. The Dagger Engine (built on BuildKit ) executes this graph with automatic parallelization and layer caching. You run dagger call ci --source . locally, get the same result in GitHub Actions, GitLab CI, or CircleCI, and never write vendor-specific YAML again.

I’ve run every Claude tier through my own workflow for months, and Claude Max 20x at $200/month is the best AI coding deal I’ve found for heavy users. It cuts the per-message cost in half versus Pro and gives me about 900 Opus 4.7 messages per 5-hour window on a 1M token context. I tracked one power user who burned 10 billion tokens in eight months for around $800 on Max; the same usage at API rates would top $15,000. Yet Anthropic’s own data shows the average Claude Code user runs about $6/day in API-equivalent spend, with 90% under $12/day. So I think Max 5x at $100/month is the sweet spot for most devs. Max 20x only pays off if you push past 225 messages per 5-hour window on a regular basis.

Can your consumer router do WireGuard VPN at 800 Mbps, isolate IoT devices into separate VLANs, and kill bufferbloat with a single queue management setting? Stock firmware almost certainly cannot. OpenWrt can.

OpenWrt is a full Linux distribution that replaces the limited manufacturer firmware on compatible routers. The router ends up behaving more like a managed switch and enterprise firewall than the box your ISP sent you. The current stable release is OpenWrt 25.12.2 (March 2026), which introduced the apk package manager (replacing opkg) and now supports over 2,200 devices. Flashing typically takes five minutes and is reversible if you keep a backup.

Every SSH connection needs the right host, port, user, and sometimes a specific key, and there is no good place to write all that down outside of ~/.ssh/config. That file stays the most underused tool in any developer’s home directory. Without it you retype ssh deploy@10.0.4.17 -p 2222 -J bastion.example.com every session, forget which IP belongs to which server two weeks later, and end up with a shell history full of nearly identical commands.
