std-uritemplate
std-uritemplate implementation for Python
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has zero dependencies, supports current Python versions (3.8–3.14), carries no known vulnerabilities, and is licensed permissively. Install it when you need RFC 6570 Level 4 URI template expansion without adding dependency weight. The single-method API and design-by-constraint approach make it a low-risk, straightforward choice for standards-compliant URL generation.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
std-uritemplate is a cross-language implementation of the URI Template specification (RFC 6570) Level 4, providing a single public method to expand template strings by substituting variable values. It takes a template string with placeholders and a dictionary of substitutions, then returns the expanded URI. The library is designed with zero dependencies, no regex usage, and no configuration options—just a straightforward expand function that handles primitive type substitutions.
The package is part of a multi-language standardization effort aimed at providing stable, maintainable URI template handling across ecosystems. It supports Python 3.8 through 3.14 and is actively maintained by an independent organization. The implementation prioritizes readability and maintenance over micro-optimizations, making it suitable for applications that need RFC 6570 compliance without external dependencies.
Use it for
- Build dynamic API URLs in REST clients by substituting host, path, and query parameters into RFC 6570 templates.
- Generate OpenAPI-compliant URIs where URI templates are part of the specification.
- Construct URLs with variable path segments and query strings without external dependencies.
- Expand templated URLs in code generation tools that rely on RFC 6570.
- Create portable URL generation logic that works identically across multiple programming languages.
