golang install goquery

Goquery is a Web Scraping library for Golang that can be used for web crawlers and data mining. If you want to use Web Scraping with Golang, installing Goquery is necessary. In this article, we will introduce how to install Goquery in Golang.

Step 1: Install Golang

First, we need to install Golang on our computer. If you don't have it installed, you can download the appropriate version from the Golang official website https://golang.org/.

Step 2: Install Goquery

Installing Goquery is very simple, just use the go get command of the Golang package management tool. Enter the following command in the terminal:

go get github.com/PuerkitoBio/goquery

This will download the goquery package and save it in the github.com/PuerkitoBio/goquery directory under the GOPATH/src directory.

Step 3: Create Golang project

Create a new Golang project and import our Goquery package.

In the command line, enter the following command:

mkdir goquery-example
cd goquery-example

Create a file named main.go in the project directory and type the following code:

package main

import (
    "fmt"
    "log"

    "github.com/PuerkitoBio/goquery"
)

func main() {
    doc, err := goquery.NewDocument("http://example.com")
    if err != nil {
        log.Fatal(err)
    }

    fmt.Println(doc.Find("title").Text())
}

This is A basic example of using Goquery to get the website title. First, we use the goquery.NewDocument() method passing the URL of the website as its parameter and store the result in a variable called doc. We then find the website's title element using the doc.Find() method and retrieve its text content using the Text() method. Finally, we print the title to the console.

Step 4: Run the project

Now, we can run our project through the following command:

go run main.go

This will execute our main.go file and display it in the console Output the title of the website.
