Collaboration Tool

SharePoint

Overview

SharePoint is Microsoft's enterprise collaboration platform that enables organizations to share and manage content, knowledge, and applications. It provides a secure, organized system for document storage, team collaboration, and workflow automation. SharePoint integrates seamlessly with Microsoft 365 services and offers extensive customization capabilities through APIs and web parts.

Details

SharePoint revolutionizes document management and collaboration in enterprise environments. As a cloud-based platform (SharePoint Online) or on-premises solution, it serves as a central hub for team sites, document libraries, lists, and workflows. The platform offers version control, co-authoring capabilities, metadata management, and advanced search functionality. SharePoint supports custom development through the SharePoint Framework (SPFx), REST APIs, and Microsoft Graph integration, enabling organizations to build tailored solutions for their specific needs.

Key Features

• Document Management: Version control, check-in/check-out, metadata tagging

Practical Examples

1. Creating a List with REST API (JavaScript)

function createSharePointList(siteUrl, accessToken) {
    $.ajax({
        url: siteUrl + "/_api/web/lists",
        type: "POST",
        data: JSON.stringify({
            '__metadata': { 'type': 'SP.List' },
            'AllowContentTypes': true,
            'BaseTemplate': 100,
            'ContentTypesEnabled': true,
            'Description': 'My project tasks list',
            'Title': 'Project Tasks'
        }),
        headers: {
            "Authorization": "Bearer " + accessToken,
            "Accept": "application/json;odata=verbose",
            "Content-Type": "application/json;odata=verbose",
            "X-RequestDigest": $("#__REQUESTDIGEST").val()
        },
        success: function(data) {
            console.log("List created successfully");
        },
        error: function(error) {
            console.error("Error creating list:", error);
        }
    });
}

2. Uploading a File (C#)

public static async Task UploadFileAsync(string siteUrl, string libraryName, string fileName, Stream fileStream)
{
    using (var client = new HttpClient())
    {
        client.DefaultRequestHeaders.Authorization = 
            new AuthenticationHeaderValue("Bearer", await GetAccessTokenAsync());
        
        var requestUrl = $"{siteUrl}/_api/web/GetFolderByServerRelativeUrl('{libraryName}')/Files/add(url='{fileName}',overwrite=true)";
        
        using (var content = new StreamContent(fileStream))
        {
            content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
            var response = await client.PostAsync(requestUrl, content);
            response.EnsureSuccessStatusCode();
        }
    }
}

3. Searching Content (JavaScript)

async function searchSharePoint(searchQuery) {
    const searchUrl = `${siteUrl}/_api/search/query?querytext='${searchQuery}'&selectproperties='Title,Path,Description,LastModifiedTime'`;
    
    const response = await fetch(searchUrl, {
        method: 'GET',
        headers: {
            'Authorization': 'Bearer ' + accessToken,
            'Accept': 'application/json;odata=verbose'
        }
    });
    
    const data = await response.json();
    const results = data.d.query.PrimaryQueryResult.RelevantResults.Table.Rows.results;
    
    return results.map(row => {
        const cells = row.Cells.results;
        return {
            title: cells.find(c => c.Key === 'Title')?.Value,
            path: cells.find(c => c.Key === 'Path')?.Value,
            description: cells.find(c => c.Key === 'Description')?.Value,
            lastModified: cells.find(c => c.Key === 'LastModifiedTime')?.Value
        };
    });
}

4. Working with Document Libraries (PowerShell)

# Connect to SharePoint Online
Connect-PnPOnline -Url "https://contoso.sharepoint.com/sites/teamsite" -Interactive

# Create a document library
New-PnPList -Title "Project Documents" -Template DocumentLibrary

# Upload files to library
Add-PnPFile -Path "C:\Documents\Report.docx" -Folder "Project Documents"

# Set metadata
Set-PnPListItem -List "Project Documents" -Identity 1 -Values @{
    "Title" = "Quarterly Report";
    "Category" = "Financial";
    "Status" = "Final"
}

# Create a view
Add-PnPView -List "Project Documents" -Title "By Category" -Fields "Title","Category","Modified" -Query "<OrderBy><FieldRef Name='Category' /></OrderBy>"

5. SharePoint Framework (SPFx) Web Part (TypeScript)

import { Version } from '@microsoft/sp-core-library';
import { BaseClientSideWebPart } from '@microsoft/sp-webpart-base';
import { SPHttpClient, SPHttpClientResponse } from '@microsoft/sp-http';

export default class ProjectDashboardWebPart extends BaseClientSideWebPart<{}> {
  
  private async getListItems(): Promise<any[]> {
    const response: SPHttpClientResponse = await this.context.spHttpClient.get(
      `${this.context.pageContext.web.absoluteUrl}/_api/web/lists/getbytitle('Project Tasks')/items`,
      SPHttpClient.configurations.v1
    );
    
    if (!response.ok) {
      throw new Error('Failed to fetch list items');
    }
    
    const data = await response.json();
    return data.value;
  }
  
  public async render(): Promise<void> {
    const items = await this.getListItems();
    
    this.domElement.innerHTML = `
      <div class="project-dashboard">
        <h2>Project Tasks</h2>
        <ul>
          ${items.map(item => `
            <li>
              <strong>${item.Title}</strong> - ${item.Status}
              <span class="due-date">${item.DueDate || 'No due date'}</span>
            </li>
          `).join('')}
        </ul>
      </div>
    `;
  }
  
  protected get dataVersion(): Version {
    return Version.parse('1.0');
  }
}
