Spring Boot: How to design an efficient REST API?

Resource collections are often enormous, and when some data has to be retrieved from them, it would be only not very efficient to always get the full list and browse it for specific items. Therefore we should design an optimized Search API.

• Filtering:

  • Narrow down query results by parameters (e.g., country, creation date).

    GET /api/cars?country=Japan
    GET /api/cars?createDate=2019-11-11

• Sorting:

  • Sort results ascending or descending by chosen parameters (e.g., by date).

    GET /api/cars?sort=createDate,asc
    GET /api/cars?sort=createDate,desc

• Paging:

  • Use "limit" to restrict results and "offset" to specify which part of the result range to show.

    GET /api/cars?limit=100
    GET /api/cars?offset=2

Combine features:

GET /api/cars?country=Japan&sort=createDate,desc&limit=100&offset=2

Results in the list of 100 cars from Japan, sorted by creation date in descending order, starting from the second page (records 101-200).

How to Run the Project

Clone source code from git

$ git clone https://github.com/Raouf25/Spring-Boot-efficient-search-API.git

Build Docker image

$ docker build -t="spring-boot-efficient-search-api" --force-rm=true .

This command runs Maven build to create a JAR package and builds the Docker image.

Note: Initial command may take time to download the base image from DockerHub

Run Docker Container

$ docker run -p 8080:8080 -it --rm spring-boot-efficient-search-api

Test Application

$ curl localhost:8080/api/cars/1

Response:

{
   "id":1,
   "manufacturer":"Acura",
   "model":"Integra",
   "type":"Small",
   "country":"Japan",
   "createDate":"1931-02-01"
}

Stop Docker Container

docker stop $(docker container ls | grep "spring-boot-efficient-search-api:*" | awk '{ print $1 }')

spring-boot-efficient-search-api's Issues

limit and offset not working

Just was testing your API and noticed that the limit and offset parms are not working, however using the page headers work fine
