MelonChart.NET

This is the Melon chart scraping library written in .NET - Top 100, Hot 100, Daily 100, Weekly 100 and Monthly 100

Prerequisites

• .NET 8.0 or later
• Visual Studio 2022 17.0+ or Visual Studio Code 1.80+ with C# Dev Kit

Getting Started

1. Install the NuGet package of this library.

   dotnet add package MelonChart.NET

   You may need to run the following command to install Playwright dependencies.

   pwsh bin/Debug/net8.0/playwright.ps1 install

2. Use the library in your code.

   var chart = new Top100Chart();
   var collection = await chart.GetChartAsync();
   foreach (var item in collection.Items)
   {
       Console.WriteLine($"{item.Rank} - {item.Title} by {item.Artist}");
   }

3. If you want to get the Hot 100 chart, use the Hot100Chart class.

   var chart = new Hot100Chart();
   var collection = await chart.GetChartAsync();
   foreach (var item in collection.Items)
   {
       Console.WriteLine($"{item.Rank} - {item.Title} by {item.Artist}");
   }

4. You can also register all the charts and get the chart by the type.

   var builder = WebApplication.CreateBuilder(args);
   builder.Services.AddKeyedScoped<IChart, Top100Chart>(ChartTypes.Top100);
   builder.Services.AddKeyedScoped<IChart, Hot100Chart>(ChartTypes.Hot100);
   builder.Services.AddKeyedScoped<IChart, Daily100Chart>(ChartTypes.Daily100);
   builder.Services.AddKeyedScoped<IChart, Weekly100Chart>(ChartTypes.Weekly100);
   builder.Services.AddKeyedScoped<IChart, Monthly100Chart>(ChartTypes.Monthly100);
   
   var app = builder.Build();
   
   app.MapGet("/top100", async ([FromKeyedServices(ChartTypes.Top100)] IChart chart) =>
   {
       var collection = await chart.GetChartAsync();
       return Results.Json(collection.Items);
   });
   
   app.MapGet("/hot100", async ([FromKeyedServices(ChartTypes.Hot100)] IChart chart) =>
   {
       var collection = await chart.GetChartAsync();
       return Results.Json(collection.Items);
   });
   
   app.MapGet("/daily100", async ([FromKeyedServices(ChartTypes.Daily100)] IChart chart) =>
   {
       var collection = await chart.GetChartAsync();
       return Results.Json(collection.Items);
   });
   
   app.MapGet("/weekly100", async ([FromKeyedServices(ChartTypes.Weekly100)] IChart chart) =>
   {
       var collection = await chart.GetChartAsync();
       return Results.Json(collection.Items);
   });
   
   app.MapGet("/monthly100", async ([FromKeyedServices(ChartTypes.Monthly100)] IChart chart) =>
   {
       var collection = await chart.GetChartAsync();
       return Results.Json(collection.Items);
   });
