```javascript
import * as dnsly from 'dnsly'
let myDnsly = new dnsly.Dnsly('google') // uses Google DNS Servers e.g 8.8.8.8
myDnsly.getRecord('example.com','AAAA') // returns promise
.then((record: dnsly.I_AAAA) => { // AAAA record for google.com, the I_AAAA will give you proper typings for the record return type
// do something
})
```

# @push.rocks/smartdns
smart dns methods written in TypeScript
## Install
To install `@push.rocks/smartdns`, use the following command with npm:
```bash
npm install @push.rocks/smartdns --save
```
Or with `yarn`:
```bash
yarn add @push.rocks/smartdns
```
Make sure you have a TypeScript environment setup to utilize the library effectively.
## Usage
`@push.rocks/smartdns` is a comprehensive library aimed at facilitating smart DNS operations, leveraging TypeScript for enhanced development experience. This section aims to cover several real-world scenarios demonstrating the library's capabilities, from basic DNS lookups to more advanced DNS management tasks.
### Getting Started
First, ensure you import the module into your TypeScript project:
```typescript
import { Smartdns } from '@push.rocks/smartdns';
```
### Basic DNS Record Lookup
Often, the need arises to fetch various DNS records for a domain. `@push.rocks/smartdns` simplifies this by providing intuitive methods.
#### Fetching A Records
To fetch an "A" record for a domain:
```typescript
const dnsManager = new Smartdns({});
const aRecords = await dnsManager.getRecordsA('example.com');
console.log(aRecords);
```
#### Fetching AAAA Records
Similarly, for "AAAA" records:
```typescript
const aaaaRecords = await dnsManager.getRecordsAAAA('example.com');
console.log(aaaaRecords);
```
### Advanced DNS Management
Beyond simple queries, `@push.rocks/smartdns` offers functionalities suitable for more complex DNS management scenarios.
#### Checking DNS Propagation
When changing DNS records, ensuring that the new records have propagated fully is crucial. `@push.rocks/smartdns` facilitates this with a method to check a DNS record until it is available globally.
```typescript
const recordType = 'TXT'; // Record type: A, AAAA, CNAME, TXT etc.
const expectedValue = 'your_expected_value';
const isAvailable = await dnsManager.checkUntilAvailable('example.com', recordType, expectedValue);
if (isAvailable) {
console.log('Record propagated successfully.');
} else {
console.log('Record propagation failed or timed out.');
}
```
### Leveraging DNS for Application Logic
DNS records can serve beyond mere domain-to-IP resolution; they can be instrumental in application logic, such as feature flagging or environment-specific configurations.
#### Example: Feature Flagging via TXT Records
Consider leveraging TXT records for enabling/disabling features dynamically without deploying new code.
```typescript
const txtRecords = await dnsManager.getRecordsTxt('features.example.com');
const featureFlags = txtRecords.reduce((acc, record) => {
const [flag, isEnabled] = record.value.split('=');
acc[flag] = isEnabled === 'true';
return acc;
}, {});
if (featureFlags['NewFeature']) {
// Logic to enable the new feature
}
```
### Conclusion
`@push.rocks/smartdns` offers a versatile set of tools for DNS querying and management, tailored for applications at any scale. The examples provided illustrate the library's potential use cases, highlighting its applicability in various scenarios from basic lookups to facilitating complex application features through DNS.
For the full spectrum of functionalities, including detailed method documentation and additional use cases, consult the module's [TypeDoc documentation](https://pushrocks.gitlab.io/smartdns/). This will serve as a comprehensive guide to leveraging `@push.rocks/smartdns` effectively in your projects.
Remember, DNS changes might take time to propagate worldwide, and the utility methods provided by `@push.rocks/smartdns` for checking record availability will be invaluable in managing these changes seamlessly.
