It has a RESTful API with two endpoints. One of them that fetches the data in the provided MongoDB collection and returns the results in the requested format. Second endpoint is to create(POST) and fetch(GET) data from an Redis database.
- Go without a web framework
- MongoDB
- Redis
You'll see .env.sample in the root directory, you should create .env file next to it and fulfill these variable to initialize the app.
-
DB_USER=
-
DB_PASS=
-
DB_HOST=
-
DB_NAME=
-
PORT=
-
REDIS_USER=
-
REDIS_PASS=
-
REDIS_HOST=
-
REDIS_PORT=
If'd rather run tests file, firstly you need to fufill .env.test file while checking .env.sample file and you'll enter in "tests" directory then run go test
Also, you'll see a todo_list.md file in the repository and it lists the matters that the app should have those feature in the future. Because those matters will make the app better.
The request payload of the first endpoint will include a JSON with 4 fields. ● “startDate” and “endDate” fields will contain the date in a “YYYY-MM-DD” format. You should filter the data using “createdAt” ● “minCount” and “maxCount” are for filtering the data. Sum of the “count” array in the documents should be between “minCount” and “maxCount”.
Response payload should have 3 main fields. ● “code” is for status of the request. 0 means success. Other values may be used for errors that you define. ● “msg” is for description of the code. You can set it to “success” for successful requests. For unsuccessful requests, you should use explanatory messages. ● “records” will include all the filtered items according to the request. This array should include items of “key”, “createdAt” and “totalCount” which is the sum the “counts” array in the document.
