Nitric Has a Free API: Build Cloud-Agnostic Serverless Apps in TypeScript

#serverless #typescript #cloud #tutorial

What is Nitric?

Nitric is a cloud-agnostic serverless framework that lets you build applications without locking into AWS, GCP, or Azure. Define your resources in code — deploy to any cloud with a single command.

Quick Start 

npm install -g @nitric/cli
nitric new my-app ts-starter
cd my-app
npm install
nitric start
Enter fullscreen mode Exit fullscreen mode

Define APIs 

import { api } from "@nitric/sdk";

const mainApi = api("main");

mainApi.get("/users/:id", async (ctx) => {
  const { id } = ctx.req.params;
  const user = await getUser(id);
  ctx.res.json(user);
});

mainApi.post("/users", async (ctx) => {
  const body = ctx.req.json();
  const user = await createUser(body);
  ctx.res.status = 201;
  ctx.res.json(user);
});

mainApi.delete("/users/:id", async (ctx) => {
  await deleteUser(ctx.req.params.id);
  ctx.res.status = 204;
});

Key-Value Storage 

import { kv } from "@nitric/sdk";

const profiles = kv("profiles").allow("get", "set", "delete");

// Set value
await profiles.set("user-123", {
  name: "Alice",
  email: "alice@example.com",
  plan: "pro",
});

// Get value
const user = await profiles.get("user-123");
console.log(user.name); // "Alice"

// Delete value
await profiles.delete("user-123");
Enter fullscreen mode Exit fullscreen mode

Buckets (File Storage) 

import { bucket } from "@nitric/sdk";

const uploads = bucket("uploads").allow("read", "write", "delete");

// Write file
await uploads.file("reports/q1-2026.pdf").write(pdfBuffer);

// Read file
const data = await uploads.file("reports/q1-2026.pdf").read();

// Generate signed URL (for client uploads)
const url = await uploads.file("user-avatar.jpg").getUploadUrl();
Enter fullscreen mode Exit fullscreen mode

Topics (Pub/Sub) 

import { topic } from "@nitric/sdk";

const orderEvents = topic("orders").allow("publish");

// Publish
await orderEvents.publish({
  type: "order.created",
  orderId: "ord_789",
  total: 149.99,
});

// Subscribe
topic("orders").subscribe(async (ctx) => {
  const event = ctx.req.json();
  console.log(`New order: ${event.orderId}`);
  await sendConfirmationEmail(event);
});
Enter fullscreen mode Exit fullscreen mode

Schedules 

import { schedule } from "@nitric/sdk";

schedule("daily-report").every("1 day", async () => {
  const metrics = await gatherMetrics();
  await sendReport(metrics);
});

schedule("cleanup").every("6 hours", async () => {
  await cleanExpiredSessions();
});
Enter fullscreen mode Exit fullscreen mode

Secrets 

import { secret } from "@nitric/sdk";

const apiKey = secret("stripe-key").allow("access");

const stripeKey = await apiKey.latest().access();
console.log(stripeKey.asString());
Enter fullscreen mode Exit fullscreen mode

Deploy to Any Cloud 

# nitric.yaml
name: my-app
services:
  - match: services/*.ts
    start: npx tsx $SERVICE_PATH
Enter fullscreen mode Exit fullscreen mode 
# Deploy to AWS
nitric up --provider aws

# Deploy to GCP
nitric up --provider gcp

# Deploy to Azure
nitric up --provider azure
Enter fullscreen mode Exit fullscreen mode

Same code, any cloud. Switch providers without changing application code.
