In this guide, you'll learn how to generate a **TypeScript SDK** for your FastAPI backend.

## Open Source SDK Generators { #open-source-sdk-generators }

A versatile option is the <a href="https://openapi-generator.tech/" class="external-link" target="_blank">OpenAPI Generator</a>, which supports **many programming languages** and can generate SDKs from your OpenAPI specification.

## Generadores de Clientes OpenAPI

Hay muchas herramientas para generar clientes desde **OpenAPI**.

Una herramienta común es <a href="https://openapi-generator.tech/" class="external-link" target="_blank">OpenAPI Generator</a>.

                10, // max attempts per IP (higher than default 5)
                100, // max global attempts per minute (much higher than default 20)
                Duration.ofSeconds(2), Duration.ofMinutes(1));

        try {
            final int numThreads = 10;
            final int attemptsPerThread = 5;

{% endfor %}

 * <p>Unlike {@code java.util.HashMap}, iteration is only proportional to the actual {@code size()},
 * which is optimal, and <i>not</i> the size of the internal hashtable, which could be much larger

 * collector by only using a constant number of internal objects.

   * higher value than you need can waste space and time, and a significantly lower value can lead
   * to thread contention. But overestimates and underestimates within an order of magnitude do not
   * usually have much noticeable impact. A value of one permits only one thread to modify the map
   * at a time, but since read operations can proceed concurrently, this still yields higher
   * concurrency than full synchronization. Defaults to 4.
