2. Quick One-Liner to Launch Qwen Code

Okay, guys, let's talk about speed and efficiency! Who doesn't love a one-liner command that gets the job done? Launching Qwen Code doesn't have to be a complicated process. In fact, you can get it up and running with a single, straightforward command. But, like getting your API key, the command you'll use depends on your location.

Launching Qwen Code Outside Mainland China

If you're coding from outside Mainland China, this is the magic spell you need:

OPENAI_BASE_URL=https://dashscope-intl.aliyuncs.com/compatible-mode/v1 \
OPENAI_API_KEY=your-api-key \
OPENAI_MODEL=qwen3-coder-plus \
qwen

Let's break this down:

OPENAI_BASE_URL=https://dashscope-intl.aliyuncs.com/compatible-mode/v1: This line sets the base URL for the Qwen Code service. It's like telling your code where to find the Qwen Code servers.
OPENAI_API_KEY=your-api-key: This is where you plug in the API key you obtained earlier. Make sure to replace your-api-key with your actual API key. This key authenticates your access to Qwen Code.
OPENAI_MODEL=qwen3-coder-plus: This specifies the model you want to use. In this case, we're using qwen3-coder-plus, which is a powerful model designed for coding tasks.
qwen: This final command actually launches Qwen Code. It tells your system to execute the Qwen Code application using the configurations you've set.

Launching Qwen Code Inside Mainland China

For developers in Mainland China, the command is similar, but the base URL is slightly different:

OPENAI_BASE_URL=https://dashscope.aliyuncs.com/compatible-mode/v1 \
OPENAI_API_KEY=你的API密钥 \
OPENAI_MODEL=qwen3-coder-plus \
qwen

The key difference here is the OPENAI_BASE_URL, which is set to https://dashscope.aliyuncs.com/compatible-mode/v1. This URL points to the Qwen Code servers within Mainland China. Also, notice 你的API密钥, which translates to "your API key." Make sure to replace this with your actual API key.

Tips for Success

Double-check your API key: A common mistake is entering the API key incorrectly. Make sure you've copied and pasted it accurately.
Environment variables: These commands set environment variables, which Qwen Code uses to configure itself. Ensure your system is set up to handle environment variables correctly.
Location matters: Use the correct OPENAI_BASE_URL based on your location (Mainland China or outside).

With this one-liner, you can quickly launch Qwen Code and start leveraging its capabilities for your coding projects. Let's move on to the next topic: using a .env file for project-specific configurations.

3. Using a .env File (Project-Local Configuration)

Alright, let's talk about keeping things organized and secure. Hardcoding sensitive information like API keys directly into your code? Not a great idea, guys! That's where .env files come to the rescue. A .env file allows you to store environment-specific variables, such as API keys and base URLs, in a separate file that's not committed to your version control system. This keeps your secrets safe and your configurations tidy.

Setting Up Your .env File

The first step is to create a file named .env in your project's root directory. This file will hold all your configuration variables. Here’s what you might put in your .env file if you're outside Mainland China:

OPENAI_BASE_URL=https://dashscope-intl.aliyuncs.com/compatible-mode/v1
OPENAI_API_KEY=your-api-key
OPENAI_MODEL=qwen3-coder-plus

And if you're in Mainland China, your .env file would look like this:

OPENAI_BASE_URL=https://dashscope.aliyuncs.com/compatible-mode/v1
OPENAI_API_KEY=your-api-key
OPENAI_MODEL=qwen3-coder-plus

Key Things to Note

Project Root: Make sure the .env file is in the root directory of your project. This is where most applications and libraries expect to find it.
Variable Format: Each variable is defined on a new line and follows the format VARIABLE_NAME=value. No spaces around the = sign!
Replace Placeholders: Don't forget to replace your-api-key with your actual API key. This is crucial for authentication.

Why Use a .env File?

Security: By storing sensitive information in a .env file, you avoid accidentally committing it to your code repository, which could expose your API key to the world.
Organization: Keeping your configurations separate from your code makes your project cleaner and easier to manage. You can easily switch between different environments (e.g., development, staging, production) by changing the values in your .env file.
Flexibility: You can define different configurations for different environments without modifying your code. This is particularly useful when working on complex projects with multiple deployment targets.

How to Load .env Variables

Once you've created your .env file, you'll need a way to load these variables into your application's environment. Many programming languages and frameworks have libraries or built-in support for this. For example, in Node.js, you can use the dotenv package. In Python, you can use the python-dotenv library.

No matter the language or framework you're using, the general process is the same: read the .env file and set the environment variables accordingly. This ensures that your application can access the configurations it needs without hardcoding them into the code.

Using a .env file is a best practice for managing configurations in any software project. It keeps your sensitive information secure, your project organized, and your deployment process flexible. Let's move on to the next section and see how to run Qwen Code without saving these variables permanently.

4. Running Qwen Code Without Saving Variables

Sometimes, you might want to run Qwen Code without permanently setting environment variables or using a .env file. Maybe you're testing things out, or you prefer not to clutter your system's environment variables. Whatever the reason, Qwen Code has you covered!

The Interactive GUI Login

When you run Qwen Code without any pre-set environment variables, it smartly drops you into an interactive GUI login. Think of it as a friendly way for Qwen Code to ask for the information it needs to get started. Instead of relying on environment variables, it prompts you directly for your API key, base URL, and model name.

How It Works

The process is pretty straightforward. When you run the qwen command without the OPENAI_BASE_URL, OPENAI_API_KEY, and OPENAI_MODEL environment variables set, Qwen Code will:

Open a prompt in your terminal or command line interface.
Instruct you to paste the required information: API Key, Base URL, and Model name.

The User Experience

This interactive approach is designed to be user-friendly, especially for those who are new to Qwen Code or prefer a more guided setup process. You simply need to copy and paste the relevant information when prompted, and Qwen Code will handle the rest. It's a convenient way to get up and running without the need for extensive configuration.
