=========

|
|
|
The world's smallest, fastest, and most secure OAuth3 (and OAuth2) JavaScript implementation
|
|
|
|
|
(Yes! works in browsers and node.js with no extra dependencies or bloat and no hacks!)
|
|
|
|
|
|
|
|
|
|
Instead of bloating your webapp and ruining the mobile experience,
|
|
|
|
|
you can use a single, small javascript file for all OAuth3 providers
|
2017-03-07 21:54:08 +00:00
|
|
|
(and almost all OAuth2 providers) with a seamless experience.
|
2017-02-13 19:35:48 +00:00
|
|
|
|
|
|
|
|
Also, instead of complicated (or worse - insecure) CLI and Desktop login methods,
|
|
|
|
|
you can easily integrate an OAuth3 flow (or broker) into any node.js app (i.e. Electron, Node-Webkit)
|
|
|
|
|
with 0 pain.

If you have no idea what you're doing

|

2017-02-21 22:32:45 +00:00
|
|
|
(people who know what they're doing should skip ahead to the tl;dr instructions)
|
|
|
|
|
|
|
|
|
|
1. Create a folder for your project named after your app, such as `example.com/`
|
|
|
|
|
2. Inside of the folder `example.com/` a folder called `assets/`
|
|
|
|
|
3. Inside of the folder `example.com/assets` a folder called `org.oauth3/`
|
2017-06-14 22:39:26 +00:00
|
|
|
4. Download [oauth3.js-v1.zip](https://git.daplie.com/OAuth3/oauth3.js/repository/archive.zip?ref=v1)
|
2017-02-21 22:32:45 +00:00
|
|
|
5. Double-click to unzip the folder.
|
|
|
|
|
6. Copy the file `oauth3.core.js` into the folder `example.com/assets/org.oauth3/`
|
|
|
|
|
7. Copy the folder `well-known` into the folder `example.com/`
|
|
|
|
|
8. Rename the folder `well-known` to `.well-known` (when you do this, it become invisible, that's okay)
|
|
|
|
|
9. Add `<script src="assets/org.oauth3/oauth3.core.js"></script>` to your `index.html`
|
|
|
|
|
9. Add `<script src="app.js"></script>` to your `index.html`
|
|
|
|
|
10. Create files in `example.com` called `app.js` and `index.html` and put this in it:
|
|
|
|
|
|
|
|
|
|
`index.html`:
|
|
|
|
|
```html

Example

-------
|
|
|
|
|
|
|
|
|
|
If you had a simple website / webapp for `example.com` with only the most necessary files,
|
|
|
|
|
it might look like this:
|
|
|
|
|
|
|
|
|
|
```

A user's e-mail can be passed into the clientParams object as `clientParams.subject`.
|
|
|
|
|
|
|
|
|
|
To auto-populate the e-mail input of the login popup, make sure the input has the class `js-oauth3-email`.
|
|
|
|
|
|
|
|
|
|
Example:
|
|
|
|
|
```js
|
|
|
|
|
if (clientParams.subject) {
|
|
|
|
|
$('.js-oauth3-email').val(clientParams.subject);
|
|
|
|
|
$('.js-authn-show').prop('disabled', false);
|
|
|
|
|
}
|
|
|

### Compatibility with Frameworks and Libraries
|
|
|
|
|
|
|
|
|
|
**jQuery**:
|
|
|
|
|
|
|
|
|
|
You're all set. Nothing else is needed.
|
|
|
|
|
|
|
|
|
|
**Angular 1**:
|
|
|
|
|
|
|
|
|
|
We've created an `Oauth3` service just for you:
|
|
|
|
|
|
|
|
|
|
```html
|
|
|
|
|
<script src="assets/org.oauth3/oauth3.ng.js"></script>
|
2017-02-13 19:35:48 +00:00
|
|
|
```
|
|
|
|
|
|
2017-02-14 23:19:21 +00:00
|
|
|
You can include that in addition to the standard file or,
|
|
|
|
|
if you don't want an extra request, just paste it into your `app.js`.

Simple API
|
|
|
|
|
----------
|
|
|
|
|
|
|
|
|
|
We include a small wrapper function of just a few lines in the bottom of `oauth3.core.js`
|
|
|
|
|
which exposes a `create` method to make using the underlying library require typing fewer keystrokes.
|
|
|
|
|
|
|
|
|
|
```
|
2017-06-14 22:39:26 +00:00
|
|
|
oauth3 = OAUTH3.create(location); // takes a location object, such as window.location
|
|
|
|
|
// to create the Client URI (your app's id)
|
|
|
|
|
// and save it to an internal state
|
2017-02-21 22:32:45 +00:00
|
|
|
|
2017-06-14 22:39:26 +00:00
|
|
|
promise = oauth3.init(location); // set and fetch your own site/app's configuration details
|
2017-02-21 22:32:45 +00:00
|
|
|
// promises your site's config
|
|
|
|
|
|
2017-06-14 22:39:26 +00:00
|
|
|
promise = oauth3.setIdentityProvider(url); // changes the Identity Provider URI (the site you're logging into),
|
|
|
|
|
// promises the provider's config // gets the config for that site (from their .well-known/oauth3),
|
|
|
|
|
// and caches it in internal state as the default

// (must be called after the setIdentityProvider promise has completed)

Core API (staging)

These APIs are NOT yet public, stable APIs, but they are good to be aware of
|
|
|
|
|
and may help with debugging.
|
|
|
|
|
|
|
|
|
|
DO NOT rely on them. Many of them WILL change (we just wanted to publish with things as they are).

URI vs URL
|
|
|
|
|
----------
|
|
|
|
|
|
|
|
|
|
See <https://danielmiessler.com/study/url-uri/#gs.=MngfAk>
|
|
|
|
|
|
|
|
|
|
Since we do not require the `protocol` to be specified, it is a URI
|
|
|
|
|
|
|
|
|
|
However, we do have a problem of disambiguation since a URI may look like a `path`:
|
|
|
|
|
|
|
|
|
|
1. https://example.com/api/org.oauth3.provider
|
2017-06-14 22:39:26 +00:00
|
|
|
2. example.com/api/org.oauth3.provider/ (not unique)
|
2017-02-07 19:19:57 +00:00
|
|
|
3. /api/org.oauth3.provider
|
|
|
|
|
4. api/org.oauth3.provider (not unique)
|
|
|
|
|
|
|
|
|
|
Therefore anywhere a URI or a Path could be used, the URI must be a URL.
|
|
|
|
|
We eliminate #2.
|
|
|
|
|
|
|
|
|
|
As a general rule I don't like rules that sometimes apply and sometimes don't,
|
|
|
|
|
so I may need to rethink this. However, there are cases where including the protocol
|
|
|
|
|
can be very ugly and confusing and we definitely need to allow relative paths.
|
|
|
|
|
|
2017-03-07 21:54:08 +00:00
|
|
|
A potential work-around would be to assume all paths are relative (eliminate #4 instead)
|
2017-02-07 19:19:57 +00:00
|
|
|
and have the path always key off of the base URL - if oauth3 directives are to be found at
|
|
|
|
|
https://example.com/username/.well-known/oauth3/directives.json then /api/whatever would refer
|
|
|
|
|
to https://example.com/username/api/whatever.
|
