Vultr DNS + Let's Encrypt for Node.js
This handles ACME dns-01 challenges, compatible with ACME.js and Greenlock.js.
Passes [acme-dns-01-test](https://git.rootprojects.org/root/acme-dns-01-test.js).
# Install
```bash
npm install --save acme-dns-01-vultr@3.x
```
# Usage
First you create an instance with your API token:
```js
var dns01 = require('acme-dns-01-vultr').create({
baseUrl: 'https://api.vultr.com/v1/dns', // default
token: 'xxxx'
});
```
Then you can use it with any compatible ACME module,
such as Greenlock.js or ACME.js.
### Greenlock.js
```js
var Greenlock = require('greenlock-express');
var greenlock = Greenlock.create({
challenges: {
'dns-01': dns01
// ...
}
});
```
See [Greenlock™ Express](https://git.rootprojects.org/root/greenlock-express.js)
and/or [Greenlock.js](https://git.rootprojects.org/root/greenlock.js) documentation for more details.
### ACME.js
```js
// TODO
```
See the [ACME.js](https://git.rootprojects.org/root/acme-v2.js) for more details.
### Build your own
```js
dns01
.set({
identifier: { value: 'foo.example.com' },
wildcard: false,
dnsHost: '_acme-challenge.foo.example.com',
dnsAuthorization: 'xxx_secret_xxx'
})
.then(function() {
console.log('TXT record set');
})
.catch(function() {
console.log('Failed to set TXT record');
});
```
See [acme-dns-01-test](https://git.rootprojects.org/root/acme-dns-01-test.js)
for more implementation details.
Vultr DNS for Let's Encrypt / ACME dns-01 challenges with ACME.js and Greenlock.js (Node.js).
# Tests
```bash
# node ./test.js domain-zone api-key
```
# node ./test.js domain-zone api-token
node ./test.js example.com xxxxxx
```
