2. How to Install DiceDB 🚀

Ready to embark on your DiceDB journey? First, learn how to install it! You can choose to install via Docker or from source code—both methods have their advantages!

2.1 Installing with Docker 🐳

If you opt for Docker, the installation process is straightforward! Just enter the following command on your command line:

docker run -p 7379:7379 dicedb/dicedb --enable-watch

• This command starts a Dice database instance using docker run.
• The -p 7379:7379 parameter maps the 7379 port of the Docker container to the 7379 port of the host machine, allowing you to access the Dice database directly via /7379.
• --enable-watch is a powerful option that activates the database’s monitoring feature, tracking data changes in real time—this option is a must! 🌟

2.2 Installing from Source Code 📦

If you prefer to build Dice from source, you can follow these steps to execute the commands step by step:

git clone https://github.com/dicedb/dice
cd dice
go run main.go --enable-watch

• git clone https://github.com/dicedb/dice clones the Dice source code from GitHub to your local environment.
• The critical step is running go run main.go --enable-watch, which not only starts the main program but also activates the data monitoring feature! 🌍

3. Examples of Using Dice 💻

Now, let’s explore how to apply Dice in projects by going through some common examples to help everyone better understand!

3.1 Using Go Lint Tools 🔍

Ensuring code quality is paramount in project development! Utilize lint tools to check your code. First, install the Go lint tool by executing the following command:

sudo su
curl -sSfL https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh | sh -s -- -b /bin v1.60.1

• This command downloads the installation script for the lint tool via curl and executes it with sh.
• The -b /bin option ensures the tool is installed in the /bin directory for global access. 😄

Once installed, you can run golangci-lint run in your project to check for potential issues in the code! 💥

3.2 Using Air for Hot Reload 🔄

During development, hot reload helps you immediately preview the effects of code changes! You can install the Air tool with the following commands:

go install github.com/air-verse/air@latest
curl -sSfL https://raw.githubusercontent.com/air-verse/air/master/install.sh | sh -s -- -b $(go env GOPATH)/bin

• go install places Air in your working environment, while the subsequent curl command uses the installation script to set it in the appropriate path for easy access.

After installation, you can start Air with the following commands:

git clone https://github.com/dicedb/dice
cd dice
air

• Once launched, Air will actively monitor file changes, automatically restarting and running code upon any modifications, greatly boosting your development efficiency! ⚡️

3.3 Running Unit Tests 🧪

To ensure the proper functionality of Dice, the project comes with built-in unit tests! Use the following command to run specific test functions:

TEST_FUNC= make unittest-one

• This command utilizes make and specifies the test function to run with the TEST_FUNC environment variable, executing the appropriate test script!

To run all unit tests, you can execute:

make unittest

Similarly, you can easily run specific or all integration tests:

TEST_FUNC= make test-one
make test

• These tests ensure the reliability and performance of the code under various scenarios! 💪

4. Performance Testing and Monitoring ⚡️

To assess the performance of Dice, you can use the following command for benchmarking:

make run_benchmark

• This command automatically runs predefined performance tests and outputs the results, helping you understand Dice’s performance under different loads, paving the way for further application optimization! 📊

4.1 Monitoring the Running Dice Instance 🔍

You may need to check the operational status of the Dice database, and can do so by using the following command to view relevant ports:

$ sudo netstat -atlpn | grep :7379

• This command employs netstat to view the services running on port 7379, filtering out the information for the Dice instance. 👍

If the port is occupied by another process, you can terminate that process with the following command to ensure your application functions properly:

$ sudo kill -9 <PID>

• <PID> is the ID of the target process, which you need to replace with the actual process number. 🌈

By following these steps, you have successfully grasped how to install DiceDB, its basic usage, and performance monitoring. These tips will lay a solid foundation for your journey with DiceDB! ✨
