Welcome to the official documentation of the Tramp.Os project, a mobile application developed in React Native with Expo. This project was undertaken as part of studies in a college course and utilizes the Jsearch API from RapidAPI to search for job opportunities and display them in the application.

The project is structured as follows: (major folder structure)

Tramp.Os/
|-- app/
|   |-- jobdetails/
|   |-- search/
|   |-- _layout.js
|   |-- home.js
|   |-- index.js
|-- assets/
|   |-- fonts/
|   |-- icons/
|   |-- images/
|-- components/
|   |-- common/
|	|   |-- cards/
|	|   |-- header/
|   |-- home/
|	|   |-- nearby/
|	|   |-- popular/
|	|   |-- welcome/
|   |-- jobdetails/
|	|   |-- about/
|	|   |-- company/
|	|   |-- footer/
|	|   |-- specifics/
|	|   |-- tabs/
|   |-- index.js
|-- constants/
|   |-- icons.js
|   |-- images.js
|   |-- index.js
|   |-- theme.js
|   hook/
|   |-- useFetch.js
|-- styles/
|   |-- search.js
|-- utils/
|   |-- index.js
|-- package.json
|-- ...

• The /components/ folder contains reusable components.

• The hooks/ folder contains the useFetch file, responsible for making calls to the Jsearch API using Axios.

Ensure that Node.js, Expo CLI, and Yarn (or npm) are installed in your development environment. If not, follow the instructions in the official Expo documentation.

# Install Expo CLI globally
npm install -g expo-cli

# Install project dependencies
npm install

Tramp.Os uses several essential dependencies for development and proper application functioning. Below are the main dependencies, along with a brief explanation of each:

Expo is a platform that facilitates the development of React Native applications by providing additional tools and services. It simplifies tasks such as accessing native device resources, making multi-platform development easier.

# Expo CLI installation
npm install -g expo-cli

React Native is a framework for building mobile applications using React and JavaScript. It enables the development of native iOS and Android apps with a common codebase.

# React Native installation
npm install react-native

Axios is a Promise-based HTTP client used for making HTTP requests. It simplifies the process of communicating with APIs, providing an easy-to-use interface for making requests and handling responses.

# Axios installation
npm install axios

JavaScript is the programming language used to develop logic and dynamic interaction in Tramp.Os. It is the primary programming language for web and mobile development, providing the ability to create interactive and responsive applications.

No separate installation of JavaScript is required, as it is interpreted by browsers or the Node.js environment.

The project uses the Jsearch API from RapidAPI to search for job opportunities. To configure the API, follow these steps:

1. Access RapidAPI.
2. Create an account or log in if you already have one.
3. Subscribe to the free plan of the Jsearch API.
4. Get the Jsearch API key on the RapidAPI settings page.
5. Replace the API key in the hook/useFetch.js file.

// src/services/api.js

import { useState, useEffect } from "react";
import axios from "axios";

const useFetch = (endpoint, query) => {
  const [data, setData] = useState([]);
  const [isLoading, setIsLoading] = useState(false);
  const [error, setError] = useState(null);
  
  const options = {
    method: "GET",
    url: `https://jsearch.p.rapidapi.com/${endpoint}`,
    headers: {
      "X-RapidAPI-Key": 'YOUR_API_KEY',
      "X-RapidAPI-Host": "jsearch.p.rapidapi.com",
    },
    params: { ...query },
  };

  
  const fetchData = async () => {
    setIsLoading(true);
    try {
      const response = await axios.request(options);
  
      setData(response.data.data);
      setIsLoading(false);
    } catch (error) {
      setError(error);
      console.log(error)
    } finally {
      setIsLoading(false);
    }
  };

  
  useEffect(() => {
    fetchData();
  }, []);

  const refetch = () => {
    setIsLoading(true);
    fetchData();
  };

  return { data, isLoading, error, refetch };
};
  

export default useFetch;

With the dependencies installed and the API key configured, you can start the project with the following command:

npx expo start

This will open the Expo Developer Tools in your browser. You can then run the app on an emulator or on a physical device using the Expo Go app.

This project was developed based on a tutorial and as part of an academic project. If you encounter difficulties or want to contribute, feel free to open an issue or submit a pull request on the GitHub repository.
