TypeScript autocomplete and type checking
Would you like your editor to support auto-completion and other advanced IDE features when editing
dnsconfig.js
? Yes you can!While DNSControl does not support TypeScript syntax in
dnsconfig.js
, you can still use TypeScript’s features in editors which support it.If you’re using Visual Studio Code (or another editor that supports TypeScript), you should now be able to see the type information in your
dnsconfig.js
file as you type. Hover over record names to read their documentation without having to open the documentation website!To set up TypeScript support in Visual Studio Code, follow these steps:
- 1.Run this command to generate the file
types-dnscontrol.d.ts
.
dnscontrol write-types
This file has all the information your editor or IDE needs. It must be in the same directory as the
dnsconfig.js
file you are editing.NOTE: Re-run the
dnscontrol write-types
command any time you upgrade DNSControl. Because it is generated from the command, it will always be correct for the version of DNSControl you are using.- 2.Tell your editor
At this point some features (autocomplete) will work. However to get the full experience, including type checking (i.e. red squiggly underlines when you misuse APIs), there is one more step.
Add these comments to the top of your
dnsconfig.js
file:dnsconfig.js
// @ts-check
/// <reference path="types-dnscontrol.d.ts" />
That should be all you need to do!
BUGS: Not all features of DNSControl work perfectly at the moment. Please report bugs and feature requests on https://github.com/StackExchange/dnscontrol/issues
NOTE: This feature is currently experimental. We might change the installation instructions as we find better ways to enable this.
Values passed to
CLI_DEFAULTS
(and the corresponding -v
command-line option) don’t show up as global variablesWorkaround: create a new
.d.ts
file in the same folder as your dnsconfig.js
file. In that file, add the following line for each variable you want to use (replacing VARIABLE_NAME
with the name of the variable)..d.ts
declare const VARIABLE_NAME: string;
This will tell TypeScript that the variable exists, and that it’s a string.
FETCH
is always shown as available, even if you don’t run DNSControl with the --allow-fetch
flag.
