# Bind Middleware for Fiber
[](https://github.com/gofiber/awesome-fiber)
Bind is a request schema validator middleware for the [Fiber](https://github.com/gofiber/fiber) web framework. It provides a convenient way to parse and validate data from different sources such as the request body, query string parameters, and route parameters.
## Installation
Use go get to install the middleware:
```bash
go get -u github.com/idan-fishman/fiber-bind
```
## Usage Example
Here are examples of how to use Bind to validate data from the request body and query parameters.
### Body Parameters
```go
package main
import (
"github.com/gofiber/fiber/v2"
"github.com/idan-fishman/fiber-bind"
)
type Person struct {
Name string `json:"name" validate:"required"`
Age int `json:"age" validate:"gte=18"`
}
func main() {
app := fiber.New()
app.Post("/person", bind.New(bind.Config{
Validator: validator.New(),
Source: bind.JSON,
}, &Person{}), func(c *fiber.Ctx) error {
person := c.Locals(bind.JSON).(*Person)
return c.JSON(person)
})
app.Listen(":3000")
}
```
### Query Parameters
```go
package main
import (
"github.com/gofiber/fiber/v2"
"github.com/idan-fishman/fiber-bind"
)
type PersonParams struct {
Name string `json:"name" validate:"required"`
}
func main() {
app := fiber.New()
app.Get("/person", bind.New(bind.Config{
Validator: validator.New(),
Source: bind.Query,
}, &PersonParams{}), func(c *fiber.Ctx) error {
params := c.Locals(bind.Query).(*PersonParams)
return c.JSON(params)
})
app.Listen(":3000")
}
```
In these examples, we define a struct that represents the data we want to validate. We then use Bind to validate the data from the request body or query parameters using the `New` function. We specify the source of the data as `bind.Body` or `bind.Query` and provide the struct as the schema to validate against. If the data is valid, it will be available in the context locals for further use.
## Configuration
Bind can be configured using the `Config` struct, which has the following fields:
- `Next` - A function that is called before the middleware is executed. If this function returns `true`, the middleware is skipped.
- `Validator` - A validator instance to use for validating the data. By default, the middleware uses the [go-playground/validator/v10](https://github.com/go-playground/validator/v10) package.
- `Source` - The source of the data to validate. This can be one of `bind.JSON`, `bind.XML`, `bind.Form`, `bind.Query`, or `bind.Params`.
- `FormFileFields` - A map where the key is the name of the file field in the form and the value is the form tag. If a field is specified here, the middleware will check if the file is uploaded in the request.
