This is a submission for the Netlify Dynamic Site Challenge: Build with Blobs.

What I Built

I have built an online poll for the common questions between developers. Each question has two options. Users can choose any one option. The votes are recorded anonymously.

Demo

Netlify Blobs

I have used Netlify Blobs to store the votes for each question.

Each blob holds a JSON array of votes for each option. Below is an example of data stored in a blob.

[341, 1231]

Here, the first element in the array is the number of votes for the first option and the second element is a number of votes for the second option.

I have used the setJSON method to set the value as json in the blob.

await store.setJSON(key, [131, 231]);

To get the value as JSON I have used the following code

await store.get(key, {
    type: "json",
});

Netlify Functions

I have used the Netlify functions as API to fetch and add votes in the blob storage.
