Synchronize source code between Local machine and Remixed IOE

In the previous 2 posts, I showed you how to use the Remix IDE tool, the structure of the tool as well as their functions, and tested a HelloWorld post so that you know how to code, compile and deploy 1. smart contract in this tool. However, in those 2 articles, the source code is only temporarily saved on the browser. If there is a cookie, it is also temporarily saved, ie, the entire source code can be lost.

In this article, I will show you how to synchronize the source code between the Local machine and the Remix IDE, that is, when we program on the Ethereum Blockchain, all changes to the source code, or configuration in the workspace will be saved to the computer. Local. And the next day you can connect and restore the source code in Local to Ethereum Blockchain to continue coding.

Step 1: Installing NPM (Node Package Manager)

Before diving into the synchronization process, it’s essential to ensure that NPM is installed on your local machine. NPM, or Node Package Manager, facilitates the creation and management of JavaScript programming libraries for Node.js. Follow these steps:

1.1 Checking NPM Installation

Open the command line and enter the following command to check if NPM is installed:

npm -version

If recognized, your computer already has NPM. If not, proceed to install NodeJS, which includes NPM.

1.2 Installing NodeJS

Install NodeJS by following the steps outlined in previous blog posts or relevant documentation.

1.3 Verifying NPM Installation

After installing NodeJS, restart your computer and retest NPM. Ensure the version is displayed, indicating a successful installation.

Step 2: Installing remixd Daemon

To enable the system to access local files from Remix IDE on the Ethereum blockchain, the remixd daemon must be installed. Follow these steps:

2.1 Installing remixd Daemon

In the command line, enter the following command:

npm install -g @remix-project/remixd

Wait for the installation to complete.

2.2 Verifying remixd Installation

Confirm that remixd is installed successfully by checking its version:

remixd --version

If the version is displayed, the installation was successful.

Step 3: Running remixd Daemon

Now, let’s run the remixd daemon to connect our local machine with Remix IDE on the Ethereum blockchain.

3.1 Setting Up the Workspace

Create a folder on your local machine where you want to sync the Ethereum blockchain projects. For example:


Navigate to the SmartContract folder using the command line.

3.2 Running remixd Daemon

Run the following command in the command line to start the remixd daemon:

remixd -s HelloWorld --remix-ide

Replace “HelloWorld” with your chosen folder name.

Step 4: Connecting Locally to Sync Source Code

With the remixd daemon running, connect Remix IDE to the local machine for source code synchronization.

4.1 Connecting from Remix IDE

In the Remix IDE Ethereum Blockchain, choose “Connect to localhost” from the Workspaces section.

4.2 Successful Connection

Click “Connect” and wait for the successful connection message. Simultaneously, the command line running remixd will display a notification for the connected workspace.

4.3 Synchronization Verification

Observe the comparison between local and Ethereum on Remix IDE. The local machine remains empty initially.

Conclusion: Streamlining Blockchain Development Workflow

Source code synchronization between the local machine and Remix IDE on the Ethereum blockchain is a critical aspect of efficient and collaborative blockchain development. By following these steps, developers can seamlessly transition between coding sessions, ensuring that all changes are saved locally and can be restored for continued development.

Additional Considerations

Adjust the folder names and paths as needed for your specific projects.

Statistical Insights: Impact on Development Efficiency

While statistical data specific to this process may not be available, the impact on development efficiency can be inferred from the streamlined workflow. By automating source code synchronization, developers can save significant time during coding sessions, leading to increased overall productivity.
