No request to the fractal server is sent directly by the browser of the user.</p> <p>The fact that every request on behalf of a user is sent through a common backend nodejs server, implies a proxy architecture. The way this works is the following: the svelte client in the browser sends a HTTP request to the nodejs server that is serving the application. This request, with the attached cookies, is then used to compose a new request to be sent to the fractal server.</p> <p>Note that the authentication context is kept thanks to cookies that establish user sessions.</p> <p>The following image provides an overview for the reader of the described architecture.</p> <p></p> <p>To avoid duplicating the logic of each fractal-server endpoint and simplify the error handling, a special Svelte route has been setup to act like a transparent proxy: <code>src/routes/api/[...path]/+server.js</code>. This is one of the suggested way to handle a different backend according to Svelte Kit FAQ.</p> <p>So, by default, the AJAX calls performed by the front-end have the same path and payload of the fractal-server API, but are sent to the Node.js Svelte back-end. Some Python API endpoints (like the <code>/auth</code> and <code>/admin</code> endpoints) that don't start with <code>/api</code> are handled in a slightly different way. Indeed, the <code>/api</code> prefix is needed by <code>hooks.server.js</code> to detect if the received call is an AJAX call, in order to process the token expiration in a custom way. To preserve this behavior for all the API calls these paths are rewritten adding the <code>/api</code> prefix.</p> <p>Summarizing, the frontend code:</p> <ul> <li>uses exactly the same path of the fractal-server API for the <code>/api</code> endpoints </li> <li>uses <code>/api/auth</code> for <code>/auth</code> endpoints</li> <li>uses <code>/api/admin</code> for <code>/admin</code> endpoints</li> </ul> <p>Other than the AJAX calls, there are also some calls to fractal-server API done by Svelte SSR, while generating the HTML page.

No request to the fractal server is sent directly by the browser of the user.</p> <p>The fact that every request on behalf of a user is sent through a common backend nodejs server, implies a proxy architecture. The way this works is the following: the svelte client in the browser sends a HTTP request to the nodejs server that is serving the application. This request, with the attached cookies, is then used to compose a new request to be sent to the fractal server.</p> <p>Note that the authentication context is kept thanks to cookies that establish user sessions.</p> <p>The following image provides an overview for the reader of the described architecture.</p> <p></p> <p>To avoid duplicating the logic of each fractal-server endpoint and simplify the error handling, a special Svelte route has been setup to act like a transparent proxy: <code>src/routes/api/[...path]/+server.js</code>. This is one of the suggested way to handle a different backend according to Svelte Kit FAQ.</p> <p>So, by default, the AJAX calls performed by the front-end have the same path and payload of the fractal-server API, but are sent to the Node.js Svelte back-end. Some Python API endpoints (like the <code>/auth</code> and <code>/admin</code> endpoints) that don't start with <code>/api</code> are handled in a slightly different way. Indeed, the <code>/api</code> prefix is needed by <code>hooks.server.js</code> to detect if the received call is an AJAX call, in order to process the token expiration in a custom way. To preserve this behavior for all the API calls these paths are rewritten adding the <code>/api</code> prefix.</p> <p>Summarizing, the frontend code:</p> <ul> <li>uses exactly the same path of the fractal-server API for the <code>/api</code> endpoints </li> <li>uses <code>/api/auth</code> for <code>/auth</code> endpoints</li> <li>uses <code>/api/admin</code> for <code>/admin</code> endpoints</li> </ul> <p>Other than the AJAX calls, there are also some calls to fractal-server API done by Svelte SSR, while generating the HTML page. These requests are defined in files under <code>src/lib/server/api/v1</code>. Here requests are grouped by contexts as <code>auth_api</code>, <code>admin_api</code>, [...].</p>"},{"location":"development/structure/#an-example-using-actions","title":"An example using actions","text":"<p>The login is still using the Svelte action approach, in which we have to extract the data from a formData object and then use it to build a JSON payload to be forwarded to fractal-server.</p> <p>Consider the code at <code>src/lib/server/api/auth_api.js:5</code>:</p> <pre><code>/**\n * Request to authenticate user\n * @param fetch\n * @param data\n * @returns {Promise&lt;*&gt;}\n */\nexport async function userAuthentication(fetch, data) {\nconst response = await fetch(FRACTAL_SERVER_HOST + '/auth/token/login', {\nmethod: 'POST',\ncredentials: 'include',\nmode: 'cors',\nbody: data\n});\n\nif (!response.ok) {\nthrow new Error('Authentication failed');\n}\n\nreturn await response.json();\n}\n</code></pre> <p>This code is responsible to call the <code>/auth/token/login</code> REST api endpoint of the fractal server.
