||
> Vanilla JavaScript binding to gdpr-guard as efficiently and easily as possible, based on data provided in the DOM | ||
<center><img src="https://github.com/Voltra/html-gdpr-guard/raw/master/html-gdpr-guard.png" alt="html-gdpr-guard logo"/></center> | ||
|
||
You can have a look at the [demo](https://voltra.github.io/html-gdpr-guard) to see it in action and inspect the DOM. | ||
|
||
## Install | ||
|
||
Via NPM: `npm i -S html-gdpr-guard` | ||
|
||
Via Yarn: `yarn add html-gdpr-guard` | ||
|
||
As a 3rd-party script tag: | ||
```html | ||
<script src="/path/to/dist/index.js"></script> | ||
``` | ||
|
||
## Use | ||
|
||
Using modules: | ||
```javascript | ||
import { | ||
restoreHtmlGdprManager, | ||
// | ||
HtmlGdprGuardError, | ||
NoManagerDefinitionError, | ||
NoNameError, | ||
NoCheckboxError, | ||
} from "html-gdpr-guard" | ||
``` | ||
|
||
Using commonjs: | ||
```javascript | ||
const { | ||
restoreHtmlGdprManager, | ||
// | ||
HtmlGdprGuardError, | ||
NoManagerDefinitionError, | ||
NoNameError, | ||
NoCheckboxError, | ||
} = require("html-gdpr-guard"); | ||
``` | ||
|
||
In the browser: | ||
```javascript | ||
const { | ||
restoreHtmlGdprManager, | ||
// | ||
HtmlGdprGuardError, | ||
NoManagerDefinitionError, | ||
NoNameError, | ||
NoCheckboxError, | ||
} = htmlGdprGuard; | ||
``` | ||
|
||
## Restore your manager instance | ||
|
||
To restore your manager instance, you will need an instance of [`GdprSavior`](https://www.ludwig-guerin.fr/gdpr-guard/interfaces/serde_GdprSavior.GdprSavior.html). | ||
The simplest one is [gdpr-guard-local](https://www.npmjs.com/package/gdpr-guard-local) which relies on local storage. | ||
|
||
The simplest way to restore your manager is to let the library do everything: | ||
```javascript | ||
const gdprSavior = getMyGdprSavior(); | ||
const manager = await restoreHtmlGdprManager(gdprSavior); | ||
``` | ||
|
||
If it fails, it will throw an instance of `HtmlGdprGuardError` which can be one of the following: | ||
* `NoManagerDefinitionError` | ||
* `NoNameError` | ||
* `NoCheckboxError` | ||
|
||
## Create your DOM structure | ||
|
||
### A guard's data | ||
|
||
#### Guard name (mandatory) | ||
|
||
A guard's data is scoped within the root element that is marked using the `data-gdpr-guard` attribute. | ||
That attribute can contain the name of your guard, otherwise the first element that has a `data-gdpr-guard-name` | ||
will be used to retrieve the guard's name. **It is mandatory** | ||
|
||
#### Guard description (optional) | ||
|
||
The guard's description can be added via a `data-gdpr-guard-description` with a value on the root element, or | ||
you can tag an element with `data-gdpr-guard-description` whose `textContent` will be treated as its description. | ||
**It is optional** | ||
|
||
It will default to an empty string. Note that if the description is the attribute's value it won't be shown to the user. | ||
|
||
#### Guard storage (optional) | ||
|
||
The guard's storage can be added via a `data-gdpr-guard-storage` attribute whose value should be the key in the [`GdprStorage`](https://www.ludwig-guerin.fr/gdpr-guard/enums/GdprStorage.GdprStorage-1.html) enum. **It is optional** | ||
|
||
#### Guard checkbox (mandatory) | ||
|
||
The checkbox that controls the guard is resolved (among the guard's children) in the following order based on the guard's name: | ||
* checkbox whose ID is the guard's name | ||
* checkbox whose `name` attribute is the guard's name | ||
* first checkbox marked with the `data-gdpr-checkbox` attribute | ||
|
||
#### Guard's required status (optional) | ||
|
||
To mark the guard as required you can: | ||
* Add the `gdpr-guard-required` attribute on the guard's root element | ||
* Add the `required` attribute on the guard's checkbox | ||
|
||
Note that, just like the way `gdpr-guard` handles required guards, if a parent is required | ||
then all of its children will be as well. | ||
|
||
You don't *have* to make your checkbox required and disabled, it will be all synced up as the guard is parsed. | ||
|
||
## A group's data | ||
|
||
A group behaves exactly like a guard, except that its root is marked using `data-gdpr-group` instead of `data-gdpr-guard`. | ||
|
||
### The manager's data | ||
|
||
The manager behaves a little bit like a guard, but has specific attributes: | ||
|
||
* `data-gdpr` is used to find the root of your manager, unless you provide it in `restoreHtmlGdprManager`'s options. Its value is treated as the manager's name. You don't have to give it a value. You can skip it altogether. | ||
* `data-gdpr-manager` that can be used to store the name of the manager if you didn't provide a value to the `data-gdpr` attribute (or the attribute itself) | ||
|
||
## Customize the restoration process | ||
|
||
You can pass a set of options as the second argument of `restoreHtmlGdprManager`. Let's inspect them one by one. | ||
|
||
### `gdprEl` HTMLElement | ||
|
||
The html element that will serve as root of the manager's definitions. By default, it will use `document.querySelector("[data-gdpr]")`. | ||
|
||
If the manager can't be found, it'll throw a `NoManagerDefinitionError`. | ||
|
||
### `autoCloseBanner` bool | ||
|
||
Whether the banner should be automatically closed once the manager has been restored if the consent banner has already been shown. | ||
|
||
### `bindEventHandlersHook` function | ||
|
||
A callback that can be used to attach event listeners to the manager's [`GdprManagerEventHub`](https://www.ludwig-guerin.fr/gdpr-guard/classes/GdprManagerEventHub.GdprManagerEventHub-1.html). | ||
|
||
The callback's signature is the following: | ||
```typescript | ||
type BindEventsCallback = (eventsHub: GdprManagerEventHub) => void; | ||
``` | ||
|
||
For instance: | ||
```javascript | ||
await restoreHtmlGdprManager(gdprSavior, { | ||
bindEventHandlersHook(eventsHub) { | ||
eventsHub.onEnable("myGuard", () => { | ||
connectToWsApi(); | ||
}); | ||
|
||
eventsHub.onDisable("myGuard", () => { | ||
disconnectFromWsApi(); | ||
}); | ||
}, | ||
}); | ||
``` | ||
|
||
### `addGuardsBeforeHook` function | ||
|
||
A callback that can be used to add guards' definitions to the [`GdprManagerBuilder`](https://www.ludwig-guerin.fr/gdpr-guard/classes/builders_GdprManagerBuilder.GdprManagerBuilder.html) instance before the library parses data from the DOM. | ||
|
||
The callback's signature is the following: | ||
```typescript | ||
type AddGuardsCallback = (managerBuilder: GdprManagerBuilder) => void; | ||
``` | ||
|
||
### `addGuardsAfterHook` function | ||
|
||
A callback that can be used to add guards' definitions to the [`GdprManagerBuilder`](https://www.ludwig-guerin.fr/gdpr-guard/classes/builders_GdprManagerBuilder.GdprManagerBuilder.html) instance after the library parsed data from the DOM. | ||
|
||
The callback's signature is the following: | ||
```typescript | ||
type AddGuardsCallback = (managerBuilder: GdprManagerBuilder) => void; | ||
``` | ||
|
||
### `onDeclineAllErrorHook` function | ||
|
||
A callback that can be used to hande/capture errors when the user click on a "decline all" button. | ||
|
||
The callback's signature is the following: | ||
```typescript | ||
type StoreErrorHandler = (didStore: boolean, error?: Error) => void; | ||
``` | ||
|
||
### `onSaveErrorHook` function | ||
|
||
A callback that can be used to hande/capture errors when the user saves their preferences. | ||
|
||
The callback's signature is the following: | ||
```typescript | ||
type StoreErrorHandler = (didStore: boolean, error?: Error) => void; | ||
``` | ||
|
||
### `onCancelErrorHook` function | ||
|
||
A callback that can be used to hande/capture errors when the user click on a "cancel" button. | ||
|
||
The callback's signature is the following: | ||
```typescript | ||
type StoreErrorHandler = (didStore: boolean, error?: Error) => void; | ||
``` | ||
|
||
### `onBannerClose` function | ||
|
||
A callback that can be used to execute code when the GDPR banner is closed. | ||
|
||
The callback's signature is the following: | ||
```typescript | ||
type BannerCallback = () => void; | ||
``` | ||
|
||
For instance: | ||
```javascript | ||
await restoreHtmlGdprManager(gdprSavior, { | ||
onBannerClose() { | ||
hideMyGdprBanner(); | ||
}, | ||
}); | ||
``` | ||
|
||
### `onBannerOpen` function | ||
|
||
A callback that can be used to execute code when the GDPR banner is closed. | ||
|
||
The callback's signature is the following: | ||
```typescript | ||
type BannerCallback = () => void; | ||
``` | ||
|
||
For instance: | ||
```javascript | ||
await restoreHtmlGdprManager(gdprSavior, { | ||
onBannerOpen() { | ||
showMyGdprBanner(); | ||
}, | ||
}); | ||
