Middleware Handler Documentation

This code defines middleware functions for an Echo web server and PocketBase application. These middleware functions include setting default headers, printing routes, and restricting the deletion of records that have references in other tables.

Functions​

BindDefaultMiddleware​

func BindDefaultMiddleware(pbx *core.ServeEvent) error

Binds default middleware to the Echo router.

  • pbx: The PocketBase serve event.

PrintRoutes​

func PrintRoutes(pbx *core.ServeEvent) error

Prints all the routes registered in the Echo router.

  • pbx: The PocketBase serve event.

RestrictRelationDelete​

func RestrictRelationDelete(pbx *core.ServeEvent) error

Restricts the deletion of records that have references in other tables.

  • pbx: The PocketBase serve event.

Example Usage​

Initializing the Middleware​

package main

import (
    "fio-backend/handler"
    "github.com/labstack/echo/v5"
    "github.com/pocketbase/pocketbase"
    "github.com/pocketbase/pocketbase/core"
)

func main() {
    // Initialize Echo
    e := echo.New()

    // Initialize PocketBase
    pb := pocketbase.New()

    // Bind default middleware
    pb.OnBeforeServe().Add(func(e *core.ServeEvent) error {
        return handler.BindDefaultMiddleware(e)
    })

    // Print routes
    pb.OnBeforeServe().Add(func(e *core.ServeEvent) error {
        return handler.PrintRoutes(e)
    })

    // Restrict relation delete
    pb.OnBeforeServe().Add(func(e *core.ServeEvent) error {
        return handler.RestrictRelationDelete(e)
    })

    // Start the server
    e.Logger.Fatal(e.Start(":8080"))
}

Making Requests​

Example Request to Print Routes​

curl -X GET http://localhost:8080/print-routes

Example Request to Restrict Relation Delete​

curl -X DELETE http://localhost:8080/api/v1/records/record123?restrict=true&excludes=table1,table2

This documentation provides an overview of the middleware functions, their purpose, and example usage. By following the example, you can initialize the middleware, bind routes, and make requests to the various endpoints.
