+# HyperExpress Benchmarking Test
+
+HyperExpress is a high performance Node.js webserver with a simple-to-use API powered by µWebSockets.js under the hood. (https://github.com/kartikk221/hyper-express)
+
+µWebSockets.js is a web server bypass for Node.js (https://github.com/uNetworking/uWebSockets.js)
+
+## Important Libraries
+
+The tests were run with:
+
+- [hyper-express](https://github.com/kartikk221/hyper-express)
+- [postgres](https://github.com/porsager/postgres)
+- [mysql2](https://github.com/sidorares/node-mysql2)
+- [lru-cache](https://github.com/isaacs/node-lru-cache)
+
+## Database
+
+There are individual handlers for each DB approach. The logic for each of them are found here:
+
+- [Postgres](database/postgres.js)
+- [MySQL](database/mysql.js)
+
+There are **no database endpoints** or drivers attached by default.
+
+To initialize the application with one of these, run any _one_ of the following commands:
+
+```sh
+$ DATABASE=postgres npm start
+$ DATABASE=mysql npm start
+```
+
+## Test Endpoints
+
+> Visit the test requirements [here](https://github.com/TechEmpower/FrameworkBenchmarks/wiki/Project-Information-Framework-Tests-Overview)
+
+```sh
+$ curl localhost:8080/json
+$ curl localhost:8080/plaintext
+
+# The following are only available with the DATABASE env var
+
+$ curl localhost:8080/db
+$ curl localhost:8080/fortunes
+
+$ curl localhost:8080/queries?queries=2
+$ curl localhost:8080/queries?queries=0
+$ curl localhost:8080/queries?queries=foo
+$ curl localhost:8080/queries?queries=501
+$ curl localhost:8080/queries?queries=

+$ curl localhost:8080/updates?queries=0
+$ curl localhost:8080/updates?queries=foo
+$ curl localhost:8080/updates?queries=501
+$ curl localhost:8080/updates?queries=
+
+$ curl localhost:8080/cached-worlds?count=2
+$ curl localhost:8080/cached-worlds?count=0
+$ curl localhost:8080/cached-worlds?count=foo
+$ curl localhost:8080/cached-worlds?count=501
+$ curl localhost:8080/cached-worlds?count=
+```
