FEND Project #3: Weather Journal

Overview

Weather Journal is the third project of Udacity Front End Web Developer nanodegree program. It requires to build a single-page JavaScript app which creates a weather record for user based on their input and data from OpenWeatherMap API.

The goal of the project is to practice with:

• setting up Node environment with Express and project dependencies
• setting up a server with GET and POST routes
• using fetch API with OpenWeatherMap API credentials
• accessing a GET route on the server side from a function called on the client side
• promise chaining
• dynamically updating properties of HTML elements

Features

• Local server (server.js) is running on port 3030.

• Data is retrieved from external OpenWeatherMap API in JSON format.

  • API calls use zip code entered by the user. Search works only for US zips.

• The following values are updated dynamically:

  • date
  • temperature
  • user input
