It includes replacements for JsonResponse, test client classes, the json_script template tag, and more, all with 100% branch coverage. A related Django proposal for a pluggable JSON backend has also been opened to bring orjson support into Django itself. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is django-orjson and what does it replace in Django? Django-orjson is a library providing drop-in replacements for Django and Django REST Framework components backed by orjson, a Rust-based JSON library. It includes an orjson-backed JsonResponse, a test client and test case classes whose response.json() uses orjson, and a replacement for Django's json_script template tag, among other components, all tested against currently supported Python and Django versions. _daily.dev helps developers track new Django ecosystem libraries like django-orjson as they weigh performance upgrades._ ### How much faster is orjson than Python's built-in json module? Orjson is roughly 10 times faster at serialization and 2 times faster at deserialization compared to Python's built-in json module. It is implemented in Rust, which underlies its performance advantage over the pure-Python json standard library module, making it a near-free performance win in Django applications where JSON handling time can be significant. _Developers evaluating Rust-backed Python libraries for performance gains can follow updates like this on daily.dev._ ### Is there a proposal to add orjson support directly into Django core? Yes, after django-orjson's initial release, Paolo Melchiorre opened a new feature proposal on Django's official new-features repository titled 'Pluggable JSON serialization/deserialization backend', listing all the places in Django that could use orjson. The proposal had gathered 14 thumbs-up reactions at the time it was reported, and community members are encouraged to add their thoughts to the discussion. _Django developers weighing in on core language proposals can track discussions like this via daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@arminajdehnia** · 0 upvotes > Is the GitHub repository at `https://github.com/mauricioabreu/django-rest-framework-orjson` the official source for the `djangorestframework-orjson` package?
