I bundled 80 boring-but-essential dev utilities into one API (QR, invoices, JWT, i18n, Japanese text)
A developer has created the Toolbelt API, which bundles 80 essential utilities for developers into a single API. This API includes functionalities such as QR code generation, JWT signing, and data format conversion. It aims to simplify the development process by reducing the need for multiple dependencies.
- ▪The Toolbelt API offers 80 utilities including QR codes, invoices, and data validation.
- ▪It is designed to be fast, cheap, and deterministic with a single key and base URL for authentication.
- ▪A unique feature of the API is its Japanese text pack, which helps normalize text input for Japanese users.
