API Selection Guide¶

When to Use REST API ✅¶

Modern JavaScript/TypeScript applications
Single-page apps (SPAs)
OData query filtering ($filter, $select, $expand)
Lightweight operations
Best compatibility (98%+ coverage)

Example:

fetch('/_api/web/lists/getbytitle("Documents")/items?$select=Title,Created')
  .then(r => r.json())
  .then(data => console.log(data.value));

When to Use SOAP Services ✅¶

Legacy .NET Framework applications
CAML query support required
Batch operations
Full SharePoint 2013/2016 compatibility

Example:

var listsSvc = new ListsService();
var items = listsSvc.GetListItems("Documents", query, viewFields, ...);

When to Use CSOM ⚠️¶

Complex object model operations
.NET applications (Framework or Core)
When you can avoid selective loading
Advanced queries requiring multiple round-trips

Example:

var ctx = new ClientContext("http://localhost:5000");
var list = ctx.Web.Lists.GetByTitle("Documents");
ctx.Load(list);  // No lambda!
ctx.ExecuteQuery();

When to Use PnP PowerShell ⚠️¶

Simple PowerShell automation
Basic CRUD operations
When REST API alternative available
Avoid cmdlets requiring selective loading

Example:

Connect-PnPOnline -Url "http://localhost:5000"
Get-PnPList  # Simple operations work
# For complex ops, use REST API instead:
Invoke-PnPSPRestMethod -Url "/_api/web/lists/..."

Performance Characteristics¶

API	Avg Response Time	Throughput	Best Use Case
REST	<5ms	High	Simple queries, bulk reads
SOAP	<10ms	Medium	Complex CAML queries
CSOM	15-30ms	Low	Multiple related objects
PnP	20-50ms	Low	Admin scripts, one-off tasks

Notes: - Response times measured on local server - Network latency adds 5-20ms - Batch operations can improve throughput

Migration from Real SharePoint¶

Use the included Migration Tool to download and import data from real SharePoint:

cd Cesivi.MigrationTool
dotnet run -- download --url https://real-sharepoint.com --site /sites/mysite
dotnet run -- import --source ./export.zip

→ Migration Guide for complete instructions

Extension & Customization¶

Plugin System¶

Create custom hooks for events and data transformations:

public class MyPlugin : ICesiviPlugin
{
    public void OnItemAdding(SPListItem item)
    {
        // Custom validation or transformation
    }
}

→ Plugin Guide

Custom Storage Providers¶

Implement IStorageService for alternative backends:

SQL Server
Azure Blob Storage
Redis
In-memory

→ Storage Providers Guide

Roadmap & Future Improvements¶

High Priority¶
