Real Code Examples from the Repository

Let's dive into some real code examples from the PocketBase repository to see how it works in practice. These examples will illustrate both basic and advanced usage patterns.

Example 1: Basic Setup and Custom Route

This example demonstrates how to set up PocketBase and create a custom route.

package main

import (
    "log"

    "github.com/pocketbase/pocketbase"
    "github.com/pocketbase/pocketbase/core"
)

func main() {
    app := pocketbase.New()

    app.OnServe().BindFunc(func(se *core.ServeEvent) error {
        // registers new "GET /hello" route
        se.Router.GET("/hello", func(re *core.RequestEvent) error {
            return re.String(200, "Hello world!")
        })

        return se.Next()
    })

    if err := app.Start(); err != nil {
        log.Fatal(err)
    }
}

Explanation: This example sets up a new PocketBase application and adds a custom route /hello that returns a simple "Hello world!" response. The OnServe().BindFunc method is used to bind a custom function to the serve event, allowing you to define custom routes and logic.

Example 2: File Upload and Management

This example demonstrates how to handle file uploads and manage files using PocketBase.

package main

import (
    "log"

    "github.com/pocketbase/pocketbase"
    "github.com/pocketbase/pocketbase/core"
)

func main() {
    app := pocketbase.New()

    app.OnServe().BindFunc(func(se *core.ServeEvent) error {
        // registers new "POST /upload" route for file uploads
        se.Router.POST("/upload", func(re *core.RequestEvent) error {
            file, _, err := re.Request.FormFile("file")
            if err != nil {
                return re.String(400, "Invalid file upload")
            }
            defer file.Close()

            // Save the file to the uploads directory
            err = re.App.FileStorage().Save("uploads", file)
            if err != nil {
                return re.String(500, "Failed to save file")
            }

            return re.String(200, "File uploaded successfully")
        })

        return se.Next()
    })

    if err := app.Start(); err != nil {
        log.Fatal(err)
    }
}

Explanation: This example sets up a custom route /upload for handling file uploads. The FormFile method is used to retrieve the uploaded file, and the Save method of the FileStorage interface is used to save the file to the uploads directory. This demonstrates how PocketBase simplifies file management.

Example 3: User Authentication

This example demonstrates how to handle user authentication using PocketBase.

package main

import (
    "log"

    "github.com/pocketbase/pocketbase"
    "github.com/pocketbase/pocketbase/core"
    "github.com/pocketbase/pocketbase/models"
)

func main() {
    app := pocketbase.New()

    app.OnServe().BindFunc(func(se *core.ServeEvent) error {
        // registers new "POST /login" route for user login
        se.Router.POST("/login", func(re *core.RequestEvent) error {
            email := re.Request.FormValue("email")
            password := re.Request.FormValue("password")

            // Authenticate the user
            user := &models.User{}
            err := re.App.Dao().FindUserByEmail(email, user)
            if err != nil {
                return re.String(400, "Invalid email or password")
            }

            if !re.App.Dao().ValidatePassword(user, password) {
                return re.String(400, "Invalid email or password")
            }

            return re.String(200, "Login successful")
        })

        return se.Next()
    })

    if err := app.Start(); err != nil {
        log.Fatal(err)
    }
}

Explanation: This example sets up a custom route /login for user authentication. The FindUserByEmail method is used to retrieve the user by email, and the ValidatePassword method is used to verify the password. This demonstrates how PocketBase simplifies user authentication.
