async-jsonstore-io

async-jsonstore-io is a library to ease the use of the services provided by jsonstore.io to save and retrieve data securely in JSON format.

---

Installation

To install the library, simply use the following command in your preferred terminal.

$ npm i async-jsonstore-io --save

This will install the library and also add it to your package.json file.

---

Usage

First of all, get your token by following the steps given below: -

• Visit jsonstore.io and click on the COPY button.
• Paste the copied link anywhere you feel like.
• The 64-character-long string that can be seen after https://www.jsonstore.io/ will be referred to as your token.

Now that you have your token, keep it somewhere safe so you don't lose it ever .

Importing the library

First of all, import the client using the require function.

const JsonStoreClient = require('async-jsonstore-io')

---

Initiating the client

Create a new instance of the client.

const jsClient = new JsonStoreClient('token_goes_here')

And now you're ready to go!

---

Saving data

The save() method is used to store the information.

FORMAT : jsclient.save(key, data);

PARAMETERS: -

• key ( string ) : The key to access your data.
• data ( any ) : The data that is stored in the key.

RETURNS : The inserted object if the operation was successful.

RAISES : Promise Rejection if some error occurred of the format specified here.

EXAMPLE: -

const JsonStoreClient = require('async-jsonstore-io');
const client = new JsonStoreClient('token-here');

let obj = {
    'this': 'is',
    a : 'sample',
    'object' : 'to send'
}

// Any object that can be parsed into JSON can be sent
client.save('some/key', obj).then(object=>{
    
    // object = obj
    console.log(object); // will print the object same as obj as 'obj' was inserted
    
    // send can also be used to modify data
    client.send('some/key', 'Some String').then(newObject=>{
        
        // you will now find 'Some String' 
        // when you try to retrieve something from 'some/key'
        
    }).catch(console.error); // Handle promise rejection
    
}).catch(console.error)

The save() function can also be used to reassign data stored at a key.

---

Fetching data

The fetch() method can be used to retrieve data.

FORMAT : jsclient.fetch(key);

PARAMETERS: -

• key ( string ) : The key from which to retrieve your data.

RETURNS : The object retrieved if the operation was successful.

RAISES : Promise Rejection if some error occurred or there was no object at the specified key as specified here.

EXAMPLE : -

const JsonStoreClient = require('async-jsonstore-io');
const client = new JsonStoreClient('token-here');

client.fetch('some/key').then(object=>{
    
    // log the retrieved object
    // is of `any` type
    
    console.log(object);
    
}).catch(console.error); // Handle promise rejection

---

Deleting data

The delete() method can be used for this purpose.

FORMAT : jsclient.delete(key);

PARAMETERS: -

• key ( string ) : The key where the object to delete was stored.

RETURNS : The request response ({"ok": true}) if the operation was successful.

RAISES : Promise Rejection if some error occurred as specified here.

EXAMPLE : -

const JsonStoreClient = require('async-jsonstore-io');
const client = new JsonStoreClient('token-here');

client.delete('some/key').then(del=>{
    
    if(del['ok']){
        // deletion was succesful
    }
    
}).catch(console.error); // Handling promise rejection

---

Note : All of the functions listed above are asynchronous you should either await them or use .then() to handle promises.

The use of try...catch or .catch() is also recommended to handle promise rejections.

---

Error

{
  "code": 404,
  "message": "Not found"
}

code : The error code returned from the request.

Message : A simple error message.

EXAMPLE : -

Listed below are some of the most common error codes: -

1. ERROR CODE 404

   Name : Not Found Error.

   This is caused when nothing is found at the specified key while using the .get() method.

2. ERROR CODE 500

   Name : Internal Server Error.

   This is caused when an invalid token is given.
