Large Scale API Orchestration

This guide explains how to use Solvix for orchestrating multiple APIs in large-scale production systems.

What is API Orchestration?

API orchestration means:

• Coordinating multiple API calls
• Managing dependencies between requests
• Avoiding duplicate calls
• Handling concurrency efficiently

Solvix provides built-in tools to manage all of these.

Why Solvix for Orchestration?

In large systems:

• Multiple services depend on each other
• Requests can overlap
• Failures can cascade
• Duplicate calls waste resources

Solvix solves this using:

• Request deduplication
• Dependency registry
• Priority queue
• Retry + circuit breaker

Basic Example

import { createClient } from "solvix";

const client = createClient({
  baseURL: "https://api.example.com",
});

const user = await client.get("/user/1");
const orders = await client.get("/orders?user=1");

Parallel Requests

const [user, orders] = await Promise.all([
  client.get("/user/1"),
  client.get("/orders?user=1"),
]);

Request Deduplication

await Promise.all([
  client.get("/user/1", { dedupeKey: "user-1" }),
  client.get("/user/1", { dedupeKey: "user-1" }),
]);

Only one network request is executed.

Request Dependencies

await client.get("/orders", {
  dependsOn: ["user"],
});

Ensures correct execution order.

Priority Queue

client.get("/critical", { priority: 1 });
client.get("/low", { priority: 5 });

Lower number = higher priority.

Rate Limiting

const client = createClient({
  rateLimit: {
    capacity: 100,
    refillRate: 20,
    interval: 1000,
  },
});

Retry Strategy

const client = createClient({
  retry: { retries: 3 },
});

Combining Everything

const client = createClient({
  retry: { retries: 3 },
  rateLimit: { capacity: 50, refillRate: 10, interval: 1000 },
});

await Promise.all([
  client.get("/user/1", { dedupeKey: "user-1", priority: 1 }),
  client.get("/orders", { dependsOn: ["user-1"] }),
]);

Real World Flow

1. Fetch user
2. Fetch dependent data
3. Deduplicate repeated calls
4. Control concurrency
5. Handle failures

Best Practices

• Use dedupe for repeated calls
• Use dependencies for order
• Use priority for critical requests
• Limit concurrency
• Combine retry + circuit breaker

Summary

Solvix enables powerful API orchestration by:

• Coordinating multiple requests
• Preventing duplication
• Managing dependencies
• Controlling load
• Ensuring reliability
