Tiny, zero-dependency, type-safe MIME constants and helpers for HTTP APIs, uploads, and file extensions.
mime-types-lite is a software package created to make a real workflow clearer, faster, and easier to trust. It turns a focused product idea into something people can use, evaluate, and understand without needing to inspect the source code.
Why mime-types-lite exists
Upload, download, and HTTP code needs dependable mappings between filenames/extensions and media types without carrying a broad database dependency into every bundle.
The goal is not simply to add another tool. mime-types-lite is designed to reduce the friction around that problem and give people a more dependable way to complete the work.
What it delivers
- Consumers can infer common media types from filenames.
- Recover preferred extensions.
- Validate/normalize media-type inputs.
- Use the same API in browser/Node module systems.
The experience
Tiny, zero-dependency, type-safe MIME constants and helpers for HTTP APIs, uploads, and file extensions.
The project brings the important parts of the workflow into one coherent experience. Its interface and behavior are shaped around the people using it, while the implementation stays focused on predictable results and honest feedback.
What to know
Every product has boundaries. These are the most important considerations for mime-types-lite:
- One extension can have aliases or ambiguous mappings.
- Lookup must normalize case/dots/paths without pretending file content was inspected.
- ESM/CommonJS consumers require stable typed exports with no runtime dependencies.
These limitations are presented openly so visitors can understand where the project works well, what it depends on, and what may change in future versions.
Current status
Published npm package. The current release demonstrates the core value of the project and the main end-to-end experience.
My role was library design and package engineering, covering typed apis, compatibility, and package distribution. The related case study explains the decisions and delivery process in greater depth for visitors who want the engineering story behind the product.
