comidapassion

During an interview with Compassion International, the recruiter shared with me that one of the apps that's developed at Compassion is an app that allows workers on the field to upload pictures of sponsored/to-be-sponsored children into the system. He also mentioned React Native and AWS as technologies they were looking for in prospective hires.

Given that I didn't have any React Native or AWS experience at the time, the recruiter felt that the job wasn't a good fit for me. As a result, I took it upon myself to learn enough React Native and AWS to create a lighthearted parody of the app he described to me. I call it "comidapassion"!

This app features a national dish from each of the 25 countries where Compassion is located and includes a way to view the recipe for each national dish within the app. It's a silly concept, but the idea is that someone could make a particular national dish on the field, take a picture of it using the app, and then upload the picture into the system.

In total, I spent approximately 35 hours developing this app, including the time it took to learn React Native and AWS S3.

Setup

1. git clone this repository.
2. cd into the directory that was created.
3. Pull in dependencies using npm install.
4. Set up an S3 bucket on AWS called "comidapassion" with a directory called "recipes". Each recipe should be specified in this directory as a JSON file (see below).
5. Add a file to the project called aws_s3_config.json and specify the credentials for accessing your AWS S3 bucket (see below).
6. Run the app using expo start.

The policy for your bucket should look something like this:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Statement1",
            "Effect": "Allow",
            "Principal": "*",
            "Action": [
                "s3:GetObject",
                "s3:PutObject"
            ],
            "Resource": [
                "arn:aws:s3:::comidapassion",
                "arn:aws:s3:::comidapassion/*"
            ]
        }
    ]
}

Each recipe's JSON file should look something like this:

{
  "name": "Nasi Goreng",
  "origin": "Indonesia",
  "url": "https://www.recipetineats.com/nasi-goreng-indonesian-fried-rice"
}

The aws_s3_config.json for your project should look something like this:

{
  "accessKeyId": <your access key ID here>,
  "secretAccessKey": <your secret access key here>
}
