# uritemplate — Implementation of RFC 6570 URI Templates

License: permissive · Maintenance: active · Popularity: top 1,000 on PyPI

## Install

pip install uritemplate
uv add uritemplate
poetry add uritemplate

## Description

uritemplate
===========

Documentation_ -- GitHub_ -- Travis-CI_

Simple python library to deal with `URI Templates`_. The API looks like

.. code-block:: python

    from uritemplate import URITemplate, expand

    # NOTE: URI params must be strings not integers

    gist_uri = 'https://api.github.com/users/sigmavirus24/gists{/gist_id}'
    t = URITemplate(gist_uri)
    print(t.expand(gist_id='123456'))
    # => https://api.github.com/users/sigmavirus24/gists/123456

    # or
    print(expand(gist_uri, gist_id='123456'))

    # also
    t.expand({'gist_id': '123456'})
    print(expand(gist_uri, {'gist_id': '123456'}))

Where it might be useful to have a class

.. code-block:: python

    import requests

    class GitHubUser(object):
        url = URITemplate('https://api.github.com/user{/login}')
        def __init__(self, name):
            self.api_url = url.expand(login=name)
            response = requests.get(self.api_url)
            if response.status_code == 200:
                self.__dict__.update(response.json())

When the module containing this class is loaded, ``GitHubUser.url`` is
evaluated and so the template is created once. It's often hard to notice...

## AI interpretation — verify before relying

Expands RFC 6570 URI templates by substituting variables into template expressions, useful for constructing dynamic URLs in API clients and web applications.

Verdict: Production-ready RFC 6570 implementation with no dependencies, active maintenance, permissive licensing, and zero known vulnerabilities. Well-suited for API client libraries and URL templating tasks.
