Some routers are not included in these results because they do not support the route structure of GitHub’s API.
To keep the benchmark comparisons fair, the router implementations are normalized to provide approximately the same set of features. The features that are normalized are how the routers handle query strings and params.
Some of the routers handle being passed the URL with the query string intact while others expect the query string to be removed. The query string gets removed in the benchmark for those that require it to be removed (using the router’s own code when possible).
Most of the routers return matched URL parameters in an object, however, the
main find() function of both koa-tree-router and trek-router returns
parameters in an array. To normalize this, the benchmark includes converting
the array to an object (which is what koa-tree-router actually does in a
different part of its codebase, so that code is used directly in the benchmark).
There are other differences between the routers that cannot be normalized, though these differences generally have a negligible effect on performance. Some of these differences include:
find-my-wayURI-decodes param values; the other routers do not- The routers support different route path features and syntax
find-my-way,@medley/router, andtrek-routersupport static path parts that overlap dynamic path parts (params/wildcards) whileanumargak,koa-tree-router, androad-runnerdo not support thisanumargakandfind-my-waysupport regex matchersroad-runnersupports wildcards in the middle of the route
