🚀 Getting Started

Note: Dark Sky had been bought by Apple and is no longer accepting new signups. For more information, read this news here.

When you have a Dark Sky Account, follow the instructions described in-detail here or below to set up the project locally on your machine.

Basic Setup

  • Clone the local-setup branch in the repository
git clone -b local-setup
  • Install the packages using the command npm install
  • Create a .env file in the root directory of the project. Add the following properties in it:
REACT_APP_ALGOLIA_PLACES_APP_ID=<your Algolia Places APP ID> (Optional)
REACT_APP_ALGOLIA_PLACES_API_KEY=<your Algolia Places Search-Only API Key> (Optional)

Algolia Places will be shutdown in 2022. For more information, read the announcement here.

  • You can obtain your Algolia Places API key here. You will get higher rate limits if you sign up and provide an api key OR it's just limited to 1000 requests/day! Moreover, code logic handles the scenario where no Algolia App ID & API key are provided since these are optional.

That's it! You can run the below available scripts to get up and running on the localhost. If you want to dive deeper into the codebase, I recommend you to check the architecture documentation to customize this application as your wish.

These instructions are very important to avoid the Blank Page issue when running the application on http://localhost:3000.

😢 Challenges

  • First, I used the OpenWeatherMap API to fetch the weather forecast data. However, 5-day forecast data was not reliable i.e. when a user on 14th March 2020 at 7:00 PM EST tries to fetch 5-day forecast data, will get forecast data starting 15th March 2020 at 12:00 AM UTC. This posed a big problem of categorizing 5-day data into individual days since the data is not always consistent and is based on UTC and not based on the user time-zone. Finally, I switched to Dark Sky API which is more reliable and provides a robust data model. However, there is a limit of 1000 calls/day.
  • Dark Sky API needs a proxy server to send and receive a response which was easy in the development stage using a browser extension like this to enable CORS in the browser. However, I can't ask every user to install this extension in their browser to check the weather forecast. So, I overcome this issue temporarily for now using the cors-anywhere library which you can get more info by checking here. However, I overcome the temporary solution and built a proxy server by deploying the Node.js  based serverless API functions on the Vercel's serverless architecture and can be accessed here.
  • Latest challenge I encountered was that Teleport API temporarily got shutdown and this led to broken autocomplete city search, and photos for favorited cities. Moreover, there is a tight coupling of code logic with this API. Now, I made a well thought highly scalable solution of using Algolia Places Rest API for fetching address based on city query as well as fetching city name based on latitude and longitude. I am very much happy about this change since it removed a lot of bad code and improved the application load times and performance.
    Note: The application UI/UX is not affected with this API change.

CORS Anywhere is a NodeJS reverse proxy which adds CORS headers to the proxied request. - Rob--W/cors-anywhere
