# Fluent API

Provides a simple way of constructing API endpoint calls with IntelliSense and chainable syntax.

### Usage sample

```go
package main

import (
	"encoding/json"
	"fmt"
	"log"

	"github.com/koltyakov/gosip"
	"github.com/koltyakov/gosip/api"
	strategy "github.com/koltyakov/gosip/auth/addin"
)

func main() {
	// Getting auth params and client
	client, err := getAuthClient()
	if err != nil {
		log.Fatalln(err)
	}

	// Binding SharePoint API
	sp := api.NewSP(client)

	// Custom headers (optional)
	headers := map[string]string{
		"Accept": "application/json;odata=minimalmetadata",
		"Accept-Language": "de-DE,de;q=0.9",
	}
	config := &api.RequestConfig{Headers: headers}

	// Chainable request sample
	data, err := sp.Conf(config).Web().Lists().Select("Id,Title").Get()
	if err != nil {
		log.Fatalln(err)
	}

	// Response object unmarshalling
	// struct depends on OData mode and API method
	res := &struct {
		Value []struct {
			ID    string `json:"Id"`
			Title string `json:"Title"`
		} `json:"value"`
	}{}

	if err := json.Unmarshal(data, &res); err != nil {
		log.Fatalf("unable to parse the response: %v", err)
	}

	for _, list := range res.Value {
		fmt.Printf("%+v\n", list)
	}
}

func getAuthClient() (*gosip.SPClient, error) {
	configPath := "./config/private.spo-addin.json"
	auth := &strategy.AuthCnfg{}
	if err := auth.ReadConfig(configPath); err != nil {
		return nil, fmt.Errorf("unable to get config: %v", err)
	}
	return &gosip.SPClient{AuthCnfg: auth}, nil
}
```

### Main concepts

* Get authenticated
* Construct root `SP` object using `api.NewSP(client)`
* Construct API calls in a fluent way
* Parse responses in the Go way
* Embrase strongly typed generic responses
* Build awesome apps in Go for SharePoint
