## Remix IDE

Remix IDE is an open source online and desktop application. A comprehensive selection of plugins with intuitive GUIs helps speed up development of Smart Contracts in Remix. Remix is used for contract development as well as studying and teaching Ethereum.

Remix IDE is part of the Remix Project, a framework for plugin-based development tools. It includes Remix Plugin Engine, Remix Libs, and Remix-IDE. Solidity contracts may be written using Remix IDE, a sophisticated open-source tool. 

It's developed in JavaScript and works in both the browser and a desktop version. Remix IDE offers components for smart contract testing, debugging, and deployment.

Remix IDE is used for the entire journey of smart contract development by users at every knowledge level. It requires no setup, fosters a fast development cycle and has a rich set of plugins with intuitive GUIs. The IDE comes in 2 flavors (web app or desktop app) and as a VSCode extension.

## Remix Plugin Manager -

Remix IDE only loads required features. The Plugin Manager is where you control which plugins are activated. This plugin design allowed the Remix team to add technologies from other teams. Also, Remix or elements of Remix may be merged into other projects.

## Remix File Explorer -
By default, Remix IDE stores files in Workspaces which are folders in your browser’s local storage.

Important - Clearing the browser storage will permanently delete all the files stored there.

Important - All the solidity files are stored under the ‘contracts’ folder in the current workspace. To create a new solidity file, add a new file inside the contracts folder with .sol extension. To edit a solidity file, click on the required .sol file.

## Remix Solidity Compiler -

The Solidity Compiler may be accessed from the icon panel by clicking the Solidity icon. When you click the compile button, the program compiles. If you want the file to be compiled each time the file is saved or when another file is selected - check the auto compile checkbox.

## Deploying Smart Contracts and running transactions -

Remix IDE is a convenient tool for building and testing your solidity smart contracts online. This short tutorial will explain how we can build and deploy our smart contract from Remix.

```
// SPDX-License-Identifier: GPL-3.0

pragma solidity >=0.7.0 <0.9.0;
contract Destructor {
 uint256 public num;
    constructor(uint256 _num){
        num = _num;
    }
    function doWork() external
    {
        selfdestruct(payable(0));
    }
    function getNum() public view returns(uint){
        return num;
    }
}
```

Above we have a simple Destructor contract which was built and tested using the online Remix IDE. To deploy this contract select the Deploy & Run Transactions tab; select injected Web3` as your environment. This will connect to the network that your wallet is connected to.

Set the input value of the constructor function if your contract has one before deploying it. Clicking on deploy will open Metamask which will ask you to confirm the transaction. After confirming the transaction, the contract will be deployed to the network.
