Developer-Friendly SDK

send.ts
import Nuntly from '@nuntly/sdk';
const nuntly = new Nuntly({});
(async () => {
const email = await nuntly.emails.send({
from: 'hello@world.net',
to: 'tomlinson@bbn-tenexa.com',
subject: 'Email',
text: 'Hey Ray, thank you for inventing email.',
});
})();

Bulletproof Error Handling

Our TypeScript SDK ensures graceful error management with clear, structured error messages and automatic retries for transient failures.

Detailed error codes and human-readable messages make debugging effortless, so you can quickly identify and resolve issues.

send.ts
import Nuntly from '@nuntly/sdk';
const nuntly = new Nuntly({});
(async () => {
try {
const email = await nuntly.emails.send({
from: 'hello@world.net',
to: 'tomlinson@bbn-tenexa.com',
subject: 'Email',
text: 'Hey Ray, thank you for inventing email.',
});
console.log(`Email sent with id ${email.id}`);
} catch (err) {
if (err instanceof Nuntly.APIError) {
console.log(err.code);
console.log(err.details);
} else {
throw err;
}
}
})();

Error Handling, Your Way

Hate try/catch? No problem. Our SDK includes a built-in safe Nuntly, giving you a cleaner, more declarative way to handle errors.

send.ts
import { createSafeNuntly } from '@nuntly/sdk/lib/safe';
const nuntly = new createSafeNuntly({});
(async () => {
const { data, error } = await nuntly.emails
.send({
from: 'hello@world.net',
to: 'tomlinson@bbn-tenexa.com',
subject: 'Email',
text: 'Hey Ray, thank you for inventing email.',
});
if (error) {
console.log(err.code);
console.log(err.details);
return;
}
console.log(`Email sent with id ${email.id}`);
})();
