Development Environment

Clone the "Shaper" main library from GitHub https://github.com/brayns-it/shaper

Create a new empty ASP.NET Core Project and simply call "InitializeShaper" and "MapShaperApi".

using Brayns.Shaper;

var builder = WebApplication.CreateBuilder(args);
builder.InitializeShaper();

var app = builder.Build();
app.MapShaperApi();

app.Run();

"MapShaperApi" will map two path in your web application:

  • /api to serve REST request with GET, POST, PUT or DELETE method
  • /rpc to serve special JSON request for the client

If you want to use also the web client (not only API) you have to clone "Shaper Web" library from GitHub https://github.com/brayns-it/shaper-web

Simply declare the web client and Web Sockets support:

app.MapShaperClient();
app.UseWebSockets();

"MapShaperClient" will catch all requests from "/client" base URI and serve the default index.html client page.

If you want to redirect also "/" path to default client page, add the following code:

app.MapShaperDefault();

Enable serving of static files and allows unknown MIME types (for example to enable Let's Encrypt HTTP validaton):

app.UseStaticFiles(new StaticFileOptions
{
    ServeUnknownFileTypes = true,
    DefaultContentType = "application/other"
});

To enable scheduled task:

app.UseShaperMonitor();

Mark the ASP.NET assembly as Shaper App container within the "AssemblyInfo" file (create it if doesn't exists):

[assembly: Brayns.Shaper.Classes.AppCollection]

Create the following directory structure:

  • code (that contains specific project code)
  • var (that contains configuration and logs)
  • var\resources (that contains embedded resources)
  • wwwroot (that contains HTTP served resources)

Complete "program.cs" example

using Brayns.Shaper;

var builder = WebApplication.CreateBuilder(args);
builder.InitializeShaper();

var app = builder.Build();
app.MapShaperApi();
app.MapShaperClient();
app.MapShaperDefault();
app.UseWebSockets();
app.UseStaticFiles(new StaticFileOptions
{
    ServeUnknownFileTypes = true,
    DefaultContentType = "application/other"
});
app.UseShaperMonitor();

app.Run();

Project Configuration

Project Configuration (csproj) must be adapted to:

  • Embed PO files with translations
  • Deploy var\resources folder
<Project Sdk="Microsoft.NET.Sdk.Web">
  ...
  ...
  
  <ItemGroup>
    <None Remove="**/*.po" />
  </ItemGroup>

  <ItemGroup>
    <EmbeddedResource Include="**/*.po" />
  </ItemGroup>

  <ItemGroup>
    <None Update="var\resources\**">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
  </ItemGroup>

  ...
  ...
</Project>

Publish Profile

Add the following lines to Publish Profile (pubxml) to preserve "var" directory:

<Project>
  ...
  ...
  
  <ItemGroup>
    <Content Update="var\resources" CopyToPublishDirectory="PreserveNewest" />
    <Content Update="var\**" CopyToPublishDirectory="Never" />
  </ItemGroup>

  ..
  ..
</Project>
