Interesting tools

Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.

Backlog MD

Task manager and kanban CLI.

What we like

Uses a Git repo with Markdown files for tracking each issue - everything exists in text on disk. CLI helps visualize the tasks as a list or kanban board. Also includes a web UI. Tasks can be created and managed from the CLI. Git used for history.

What we don't like

No dark mode for the web UI.

Flox Build & Publish

Reproducible Nix builds and packages.

What we like

Tooling makes it easy to create reproducible builds. Include runtime dependencies and publish packages that are ready to execute. Everything runs in a sandbox. Package output can include configs, docs, examples, bundled ready to run.

What we don't like

You must specifically build, package, and publish for every system architecture.

TSTyche

Type testing for TypeScript.

What we like

Makes testing types easier. Includes expect style assertions e.g. toBe(), toBeCallableWith(). Intuitive helpers for test(), it(), describe(). Test runner can specify filters, paths, and target specific TypeScript versions.

What we don't like

Testing many versions of TypeScript can be slow.
