Introduction to Add-Values API

The add-values API is a powerful tool designed to streamline the process of adding and managing values in various applications. By leveraging this API, developers can enhance their apps’ functionality and provide users with a seamless experience. In this guide, we will explore the add-values API and provide numerous examples to help you get started.

Let’s dive into some key functionalities and code snippets:

API Examples

1. Adding Single Value

This example demonstrates how to add a single value using the add-values API:

const addValue = (value) => {
  return fetch('/api/add', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ value })
  })
  .then(response => response.json())
  .catch(error => console.error('Error:', error));
};
addValue('newValue');

2. Adding Multiple Values

Here is how you can add multiple values at once:

const addValues = (values) => {
  return fetch('/api/add-multiple', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ values })
  })
  .then(response => response.json())
  .catch(error => console.error('Error:', error));
};
addValues(['value1', 'value2', 'value3']);

3. Updating Existing Value

Example for updating an existing value:

const updateValue = (id, newValue) => {
  return fetch(`/api/update/${id}`, {
    method: 'PUT',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ value: newValue })
  })
  .then(response => response.json())
  .catch(error => console.error('Error:', error));
};
updateValue(1, 'updatedValue');

4. Deleting a Value

To delete a value, use the following API example:

const deleteValue = (id) => {
  return fetch(`/api/delete/${id}`, {
    method: 'DELETE',
    headers: {
      'Content-Type': 'application/json'
    },
  })
  .then(response => response.json())
  .catch(error => console.error('Error:', error));
};
deleteValue(2);

5. Fetching All Values

You can fetch all values with the following code:

const fetchAllValues = () => {
  return fetch('/api/values')
    .then(response => response.json())
    .catch(error => console.error('Error:', error));
};
fetchAllValues().then(data => console.log(data));

Application Example

Now, let’s see how these APIs can be integrated into an app. Here’s a simple example:

import React, { useState, useEffect } from 'react';

const App = () => {
  const [values, setValues] = useState([]);
  const [newValue, setNewValue] = useState('');

  useEffect(() => {
    fetchAllValues().then(setValues);
  }, []);

  const handleAddValue = () => {
    addValue(newValue).then(() => {
      fetchAllValues().then(setValues);
      setNewValue('');
    });
  };

  return (
    

      
Values
      

        {values.map(value => (
          
{value.name}
        ))}
      
       setNewValue(e.target.value)} 
      />
      Add Value
    
  );
};

export default App;

This app allows users to view, add, and manage values seamlessly. Using the provided APIs, we ensure that the app is dynamic and user-friendly.

Happy coding!
