- Fastify is a fast and low overhead web framework for Node.js.
- This package shows how fast it is comparatively.
- For metrics (cold-start) see metrics.md
To be included in this list, the framework should captivate users' interest. We have identified the following minimal requirements:
- Ensure active usage: a minimum of 500 downloads per week
- Maintain an active repository with at least one event (comment, issue, PR) in the last month
- The framework must use the Node.js HTTP module
Clone this repo. Then
node ./benchmark [arguments (optional)]
-h: Help on how to use the tool.compare: Get comparative data for your benchmarks.
You may also compare all test results, at once, in a single table;
benchmark compare -t
You can also extend the comparison table with percentage values based on fastest result;
benchmark compare -p
