Summary: Go uses Wasm to run code in the browser, support depends on browser version. For browser compatibility, check for WebAssembly support, and for performance optimization, use non-blocking I/O, minimized DOM operations, cached resources, and Web Workers. Practical examples demonstrate the process of creating interactive web pages using Go.

Golang Browser Compatibility and Best Practices

In today’s connected world, make sure your Go applications Smooth operation in different browsers is crucial. This article explores Go browser compatibility and best practices to help you build compatible, high-performance web applications.

Compatibility

Go uses WebAssembly (Wasm) to run code in the browser. While most modern browsers support Wasm, not all browsers support it in the same way.

Determine browser support

To determine if the browser supports Wasm, you can use the following code:

import (
    "syscall/js"
)

func main() {
    js.Global().Get("WebAssembly").Call("instantiate") // 尝试实例化一个 Wasm 模块
}

If the browser supports Wasm, the code No error will be thrown. Otherwise, an error will be thrown.

Optimize performance

Here are some best practices for optimizing the performance of your Go application in the browser:

Use Non-blocking I/O: Go’s packages channel, goroutine and sync.Mutex are used to write concurrent and non-blocking code. Use them to prevent your application from hanging, thereby increasing responsiveness.
Minimize DOM operations: Frequent DOM operations will slow down the application. Use virtual DOM or similar technology where possible to reduce rendering times.
Cache resources: Cache static resources to reduce the number of HTTP requests by specifying cache headers. This can improve page loading speed.
Using Web Workers: Web Workers are JavaScript scripts that can run in a separate thread. They can be used to perform time-consuming tasks, thereby increasing responsiveness.

Practical Case

The following is a simple example of a Go application that creates interactive web pages in the browser:

main.go

package main

import (
    "syscall/js"
)

func main() {
    document := js.Global().Get("document")
    button := document.Call("createElement", "button")
    button.Set("innerHTML", "点击我")
    button.Set("onclick", js.FuncOf(func(this js.Value, args []js.Value) interface{} {
        document.Call("write", "按钮被点击了！")
        return nil
    }))
    document.Get("body").Call("appendChild", button)
}

index.html

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Go WebApp</title>
    <script src="main.wasm"></script>
</head>
<body>
</body>
</html>

To run this example, compile the main.go file using the Go command:

go build -o main.wasm main.go

Then, open the index.html file in a browser that supports Wasm.

C and Golang: When Performance is CrucialApr 13, 2025 am 12:11 AM

C is more suitable for scenarios where direct control of hardware resources and high performance optimization is required, while Golang is more suitable for scenarios where rapid development and high concurrency processing are required. 1.C's advantage lies in its close to hardware characteristics and high optimization capabilities, which are suitable for high-performance needs such as game development. 2.Golang's advantage lies in its concise syntax and natural concurrency support, which is suitable for high concurrency service development.

Golang in Action: Real-World Examples and ApplicationsApr 12, 2025 am 12:11 AM

Golang excels in practical applications and is known for its simplicity, efficiency and concurrency. 1) Concurrent programming is implemented through Goroutines and Channels, 2) Flexible code is written using interfaces and polymorphisms, 3) Simplify network programming with net/http packages, 4) Build efficient concurrent crawlers, 5) Debugging and optimizing through tools and best practices.

Golang: The Go Programming Language ExplainedApr 10, 2025 am 11:18 AM

The core features of Go include garbage collection, static linking and concurrency support. 1. The concurrency model of Go language realizes efficient concurrent programming through goroutine and channel. 2. Interfaces and polymorphisms are implemented through interface methods, so that different types can be processed in a unified manner. 3. The basic usage demonstrates the efficiency of function definition and call. 4. In advanced usage, slices provide powerful functions of dynamic resizing. 5. Common errors such as race conditions can be detected and resolved through getest-race. 6. Performance optimization Reuse objects through sync.Pool to reduce garbage collection pressure.

Golang's Purpose: Building Efficient and Scalable SystemsApr 09, 2025 pm 05:17 PM

Go language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.
