Autocomplete Web Service using GoLang

This is a simple test of an Autocomplete web service for Emapta-Zesty.io. The purpose is to return a list of Shakespeare's works based on the fragment that the user will provide or input. In this case, we will be using a query to simulate user's input. Shakespeare's works' list will be extracted from a JSON file. Each item on the JSON file contains only 2 itemms.

{
    "Title": "Title of the work",
    "ReadCount": 0
}

The result is based on how frequent the user has accessed an item which is the ReadCount. If more than 1 item have equal frequency, the service will then lookup for the closest Title from the fragment provided. If still more than 1 item are equal, result will now be based alphabetically. Moreover, result is limited to 25 results only. This limit can be adjusted by modifying the constant value of the resultLimit inside main.go file.

Feel free to edit the JSON file. Update each ReadCount values to your likings. I already updated a couple of ReadCount values for Twelfth Night (4) and Two Gentlemen of Verona(3) so results will more likely to show these two Titles. The rest are valued 0.

You can also update the threshold for determining the amount of levenshtein distance by modifying the multiplier value of thresholdMultiplier inside main.go.

Installation:

Using VSCode:

1. Open a new window of VSCode.
2. Drag the folder 'autocomplete-test' to the newly opened VSCode window.
3. Open a new terminal (Testminal->New Terminal) or press Ctrl+Shift-`
4. Type go run main.go and hit Enter. If no errors, server is already running.
5. Copy and paste this URL to any browser: http://localhost:9000/autocomplete?term=th

Using Docker:

1. Make sure Docker is running.
2. Make sure that the DockerFile file is included in the files.
3. In the terminal, type and run docker build -t <NameYourImage> ..
4. Then type docker run -p 9000:9000 -tid <NameYourImage>.
5. Copy and paste this URL to any browser: http://localhost:9000/autocomplete?term=th

Using the build file

1. There are 2 files included, main.exe and main, for Windows and Linux respectively.
2. Make sure those files are in the root directory where the main.go resides.
3. Simply run the main.exe file. A console window will open.
4. Copy and paste this URL to any browser: http://localhost:9000/autocomplete?term=th

• Note that, I wasn't able to test this on a linux machine. Only on a linux docker image.

Other ways to access the web service

Using cURL:

1. Make sure the server is running.
2. Type in curl http://localhost:9000/autocomplete?term=th in a terminal window and hit Enter.
