&lt;p&gt;This sample shows how to compose a middleware component with a business logic component using &lt;a href&#x3D;&quot;https://www.fermyon.com/blog/introducing-spin-v2&quot;&gt;Spin 2.0&lt;/a&gt; and the Component Model. &lt;/p&gt;
&lt;h2&gt;Instructions&lt;/h2&gt;
&lt;h3&gt;Install Prerequisites&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;Install &lt;a href&#x3D;&quot;https://github.com/bytecodealliance/cargo-component&quot;&gt;&lt;code&gt;cargo component&lt;/code&gt;&lt;/a&gt;:&lt;/li&gt;
&lt;/ul&gt;
&lt;pre&gt;&lt;code class&#x3D;&quot;language-bash&quot;&gt;cargo install --git https://github.com/bytecodealliance/cargo-component cargo-component
&lt;/code&gt;&lt;/pre&gt;
&lt;ul&gt;
&lt;li&gt;Install a fork of &lt;a href&#x3D;&quot;https://github.com/dicej/wasm-tools/tree/wasm-compose-resource-imports&quot;&gt;wasm-tools&lt;/a&gt;:&lt;/li&gt;
&lt;/ul&gt;
&lt;pre&gt;&lt;code class&#x3D;&quot;language-bash&quot;&gt;cargo install --git https://github.com/dicej/wasm-tools --branch wasm-compose-resource-imports wasm-tools --locked
&lt;/code&gt;&lt;/pre&gt;
&lt;ul&gt;
&lt;li&gt;Install latest &lt;a href&#x3D;&quot;https://developer.fermyon.com/spin/v2/install&quot;&gt;Spin&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Create an OAuth App in your &lt;a href&#x3D;&quot;https://github.com/settings/developers&quot;&gt;GitHub Developer Settings&lt;/a&gt;. 
&lt;ul&gt;
&lt;li&gt;Set the callback URL to &lt;code&gt;http://127.0.0.1:3000/login/callback&lt;/code&gt;. &lt;/li&gt;
&lt;li&gt;Accept defaults and input dummy values for the rest of the fields.&lt;/li&gt;
&lt;li&gt;Save the Client ID&lt;/li&gt;
&lt;li&gt;Generate a new Client Secret and save that as well&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;h3&gt;Build And Run The Spin App&lt;/h3&gt;
&lt;pre&gt;&lt;code class&#x3D;&quot;language-bash&quot;&gt;# Build the middleware
cargo component build --manifest-path github-oauth/Cargo.toml --release

# Build and run the example
spin up --build -f example -e CLIENT_ID&#x3D;&amp;lt;YOUR_GITHUB_APP_CLIENT_ID&amp;gt; -e CLIENT_SECRET&#x3D;&amp;lt;YOUR_GITHUB_APP_CLIENT_SECRET&amp;gt;

# Open http://127.0.0.1:3000/login in a browser

# Deploy to Fermyon Cloud
spin cloud deploy
&lt;/code&gt;&lt;/pre&gt;
