In the world of software and automation, complexity is the enemy of reliability. The more moving parts a system has, the more ways it can fail. We've all seen it: a multi-step workflow grinds to a halt because one small, seemingly insignificant part breaks. The entire process fails, data is left in an inconsistent state, and manual intervention is required.
But what if we could build our automations from components that were fundamentally reliable? What if each step was a self-contained, indivisible, and guaranteed unit of work?
This is the principle behind atomic actions, the fundamental building block for creating reliable, scalable, and agentic workflows. On the .do platform, this concept is brought to life through action.do.
An atomic action is the smallest, indivisible unit of work in a process. Think of it like a LEGO brick. You can't break a single brick into smaller pieces; it's a complete unit on its own. Similarly, an atomic action performs a single, specific task that either succeeds completely or fails completely—there is no partial success.
Good examples of atomic actions include:
By breaking down a complex process like "Onboard a New Customer" into a series of atomic actions (create.user, send.welcome_email, update.crm_record), you ensure that each step is distinct, testable, and independently executable.
You might be thinking, "Isn't this just a function?" Not quite. While a function in your code performs a task, an atomic action on the .do platform elevates that function to a fully managed service.
Calling a regular function leaves many things up to you:
action.do handles all of this for you. Every execution of an action.do is:
This transforms your logic from a simple piece of code into a robust, reusable component for Business-as-Code.
Let's see how this works. Imagine you want to send a welcome email. Instead of writing your own SMTP logic, you can simply execute the email.send action.
import { Do } from '@do-sdk/core';
// Initialize the .do client with your API key
const doClient = new Do({ apiKey: 'YOUR_API_KEY' });
// Execute a single, atomic action like sending an email
async function sendWelcomeEmail(to: string, name: string) {
try {
const result = await doClient.action('email.send').run({
to,
subject: `Welcome to our platform, ${name}! Robustly.`,
body: `Hi ${name},\n\nWe're thrilled to have you join us.`
});
console.log('Action Succeeded:', result.id);
return result;
} catch (error) {
console.error('Action Failed:', error);
}
}
// Trigger the action
sendWelcomeEmail('new.user@example.com', 'Alex');
The line doClient.action('email.send').run(...) does more than just call a function. It securely invokes a managed service responsible for one thing: sending an email. If the email service is temporarily down, the .do platform can automatically retry based on your configuration, ensuring your workflow doesn't fail due to a transient issue.
The true power emerges when you start composing these atomic actions to create sophisticated workflows. Because each block is reliable, the entire structure becomes resilient.
This approach is the foundation for creating Agentic Workflows—automations that can operate independently, handle errors gracefully, and make decisions without human intervention. When an action fails, the workflow doesn't just crash. The platform's built-in resilience allows it to:
This is a paradigm shift from brittle scripts to intelligent, self-healing automated business processes.
An atomic action is the smallest, indivisible unit of work. It performs a single, specific task—like sending an email or updating a database record—ensuring each step in your workflow is reliable, testable, and independently executable.
action.do elevates a function to a managed service. Every execution is logged, monitored, secured, and scalable. It provides built-in retry logic, idempotency, and versioning, making it perfect for building resilient, distributed systems as Business-as-Code.
Absolutely. The .do platform empowers you to wrap your own code, scripts, or third-party API calls into a custom action. This transforms your unique business logic into a standardized, reusable, and callable Service-as-Software.
The .do platform has built-in resilience. You can configure automatic retry policies with exponential backoff, define custom error handling logic, or trigger compensatory actions to ensure your workflows can gracefully handle failures without manual intervention.
Complex processes don't have to be fragile. By embracing the principle of atomic actions, you can build automations that are robust, scalable, and easy to maintain.
action.do provides the fundamental building block for this new era of workflow automation. It allows you to execute atomic actions, precisely, turning your business logic into a composition of reliable, managed software services.
