<h1>Deployd</h1>
<p>A modern web server for front-end developers.</p>
</div>
</div>
<h2>Basics</h2>
<p>Deployd is a web server built on resources, in the style of REST. In the dashboard, you can build your app by creating resources and configuring them to work the way the want.</p>
<h2>Routing</h2>
<p>When Deployd receives an HTTP request, it checks the first part of the URL to see which resource should handle the request:</p>
<ul>
<li><strong>/todos</strong>/12345 - handled by the <strong>/todos</strong> resource</li>
<li><strong>/admin</strong>/users/12345 - handled by the <strong>/admin</strong> resource, if it exists (you cannot create multi-part resource names)</li>
<li><strong>/img</strong>/bg.jpg - handled by the <strong>/img</strong> resource</li>
<li><strong>/</strong>index.html - handled by the <strong>/</strong> resource</li>
</ul>
<h2>Reserved resource names</h2>
<p>Certain resource paths are used internally by Deployd. You should not create resources with these names:</p>
<ul>
<li>/keys</li>
<li>/types</li>
<li>/resources</li>
<li>/sessions</li>
<li>/property-types</li>
<li>/__dashboard</li>
</ul>
<h2>REST</h2>
<p>REST is a web service design pattern that conforms closely to HTTP itself. In Deployd, HTTP methods or verbs have meaning:</p>
<ul>
<li><strong>GET</strong> - Load a resource without modifying it (this is a browser's default method)</li>
<li><strong>POST</strong> - Create a resource, or send data to a special that doesn't fit within these methods</li>
<li><strong>PUT</strong> - Update an existing resource</li>
<li><strong>DELETE</strong> - Destroy an existing resource</li>
</ul>
<p>In Deployd, HTTP response codes are also important:</p>
<ul>
<li><strong>200</strong> OK - The request succeeded</li>
<li><strong>204</strong> No Content - The request succeeded, but there is no content to return (for example, after a deletion, or requesting an empty list)</li>
<li><strong>400</strong> Bad Request - The request did not pass validation. Change the parameters and try again.</li>
<li><strong>401</strong> Unauthorized - The request's session does not have permission to access that resource. </li>
<li><strong>404</strong> Not Found - That URL does not reference an existing resource</li>
<li><strong>500</strong> Internal Server Error - Deployd has failed to process the request due to an unexpected error.</li>
</ul>
<h2>Cross-Origin AJAX</h2>
<p>Deployd is configured so that you can easily develop a web app locally on your computer. It will send Access-Control-Allow-Origin HTTP headers if a request is coming from localhost or your filesystem, which will allow modern web browsers to use AJAX normally. It will not send these headers for any other domain.</p>
<h1>Collection Resource</h1>
<p>A Collection resource allows your app to save and load data in a simple schema.</p>
<h2>Setting up a collection</h2>
<p>After creating a Collection resource in the dashboard, you can set up the schema by dragging properties into the database and naming them. </p>
<p>The grid view below the property list allows you to edit the Collection manually.</p>
<h2>Property types</h2>
<p>You can currently use the following property types:</p>
<ul>
<li><strong>String</strong> - Arbritrary text data</li>
<li><strong>Number</strong> - Numeric value, supports floating points</li>
<li><strong>Boolean</strong> - True or false</li>
<li><strong>Date</strong> - A specific point in time</li>
</ul>
<h2>Formats</h2>
<p>You must format the request body as a JSON string and pass the header "Content-Type: application/json".</p>
<h2>Saving data</h2>
<p>To save data, send a POST request to the root of the Collection:</p>
<pre><code>POST /people
Content-Type: application/json
{
"age": 23,
"firstName": "Joe",
"lastName": "Smith"
}
</code></pre>
<p>The server will respond with the object, which will have a new <code>_id</code> property. </p>
<pre><code>200 OK
{
"_id": "4f71fc7c2ba744786f000001",
"age": 23,
"firstName": "Joe",
"lastName": "Smith"
}
</code></pre>
<p>This <code>_id</code> is used to find the object's URL (i.e. <code>/people/4f71fc7c2ba744786f000001</code>)</p>
<h2>Listing data</h2>
<p>A GET request to the root of the Collection will return an array of objects in the collection:</p>
<pre><code>GET /people
200 OK
[
{
"_id": "4f71fc7c2ba744786f000001",
"age": 23,
"firstName": "Joe",
"lastName": "Smith"
},
{
"_id": "4f71fe8b2ba744786f000002",
"age": 36,
"firstName": "John",
"lastName": "Doe"
}
]
</code></pre>
<h2>Retrieving a specific object</h2>
<p>A GET request at an object's URL will return the properties of that object:</p>
<pre><code>GET /people/4f71fc7c2ba744786f000001
200 OK
{
"_id": "4f71fc7c2ba744786f000001",
"age": 23,
"firstName": "Joe",
"lastName": "Smith"
}
</code></pre>
<h2>Updating an object</h2>
<p>A PUT request at an object's URL will update the object. You must include all properties except for <code>_id</code>.</p>
<pre><code>PUT /people/4f71fc7c2ba744786f000001
Content-Type: application/json
{
"age": 24,
"firstName": "Fred",
"lastName": "Smith"
}
</code></pre>
<p>The server will respond with the entire object:</p>
<pre><code>200 OK
{
"_id": "4f71fc7c2ba744786f000001",
"age": 24,
"firstName": "Fred",
"lastName": "Smith"
}
</code></pre>
<h2>Deleting an object</h2>
<p>A DELETE request at an object's URL will permanently remove that object from the collection:</p>
<pre><code>DELETE /people/4f71fc7c2ba744786f000001
204 No Content
</code></pre>
<h2>Filtering results</h2>
<p>You can add querystring parameters to a GET request at the root to filter the results by properties specified:</p>
<pre><code>GET /people?firstName=Joe&amp;lastName=Smith
</code></pre>
<p><strong>NOTE</strong>: This currently only works for String properties.</p>
<h2>Advanced querying</h2>
<p>If you need to query additional types of properties, pass a JSON object as the <code>q</code> parameter with the properties you wish to filter:</p>
<pre><code>GET /people?q={
"age": 23
}
</code></pre>
<p>The <code>q</code> parameter supports <a href="http://www.mongodb.org/display/DOCS/Advanced+Queries">MongoDB's query language</a> for particularly advanced queries. Note that Collections do not currently support embedded documents or arrays.</p>
<pre><code>GET /people?q={
"$orderby": { "age": 1 },
"name": {
"$regex": "^j"
"$options": "i",
}
}
</code></pre>
<h1>Collection Event Handlers</h1>
<p>You can attach micro-scripts to events to add logic and validation to your objects. Collections currently support the following events:</p>
<ul>
<li><strong>On Get</strong> - called when data is read</li>
<li><strong>On Post</strong> - called when data is created</li>
<li><strong>On Put</strong> - called when data is updated</li>
<li><strong>On Delete</strong> - called when data is destroyed</li>
</ul>
<h2>Reading and setting properties</h2>
<p>In an event micro-script, the <code>this</code> object refers to the current object, and has all of the properties of the object.</p>
<p>You can set values on the <code>this</code> object during an On Post or On Put event. These changes will be saved to the database.</p>
<pre><code>// On Post:
this.dateCreated = new Date();
// On Put:
this.totalScore = this.level1Points + this.level2Points;
</code></pre>
<h2>Accessing the current user</h2>
<p>If the request is coming from a logged in User, you can use the "me" object to access their properties.</p>
<pre><code>// On Post:
this.creator = me._id;
</code></pre>
<h2>Cancelling an event</h2>
<p>You can stop any event by calling the <code>cancel(message, [code])</code> method.</p>
<pre><code>//On Delete:
if (this.protected) {
cancel('This post is protected and cannot be deleted');
}
DELETE /posts/123456
400 Bad Request
{
"message": "This post is protected and cannot be deleted"
}
</code></pre>
<p>You can pass an integer to the <code>cancel()</code> method as the second parameter to set the HTTP status code. For example, 401 means "Unauthorized".</p>
<pre><code>//On Put
if (this.creator !== me._id) {
cancel("You cannot view this post because it is not yours!", 401);
}
PUT /posts/13456
Content-Type: application/json
{ ... }
401 Unauthorized
{
"message": "You cannot view this post because it is not yours!"
}
</code></pre>
<h2>Validation</h2>
<p>Use the <code>error(name, message)</code> function to add a validation error.</p>
<pre><code>//On Post
if (this.age &lt; 18) {
error('age', 'must be older than 18')
}
POST /people
{
"firstName": "Joe",
"lastName": "Smith",
"age": 12
}
400 Bad Request
{
errors: {
"age": "must be older than 18"
}
}
</code></pre>
<h2>Hiding properties</h2>
<p>If you wish to hide certain properties from a user, use the <code>hide(propertyName)</code> function.</p>
<pre><code>//On Get
if (this.creator !== me._id) {
hide('lastName');
hide('age');
}
</code></pre>
<h2>Protecting properties from modification</h2>
<p>Use the <code>protect(propertyName)</code> function to protect specified properties during a POST or PUT.</p>
<pre><code>//On Put
protect('createdDate');
</code></pre>
<hr /><h1>Files Resource</h1>
<p>The Files Resource allows you host static files from your app, such as HTML, browser JavaScript, CSS, images, and videos. </p>
<h2>Accessing files</h2>
<p>Send a GET request with the filename to load the raw file. This is how browsers request pages and files by default.</p>
<pre><code>GET /files/bg.jpg
</code></pre>
<h2>Folders</h2>
<p>If you prefer to have separate folders for Javascript, CSS, and images, create multiple Static Resources at the paths you want to store the files.</p>
<p>You can also give a Static Resource an empty path <code>/</code>. This will assign it to the root of your app.</p>
<h2>Home page</h2>
<p>If a Static Resource receives a request without a filename, it will automatically redirect to "index.html" if available.</p>
<hr /><h1>User Collection Resource</h1>
<p>A User Collection resource behaves much like the standard Collection resource, but adds the ability to authenticate with a username and password.</p>
<h2>Special properties</h2>
<p>The User Collection contains two special properties:</p>
<ul>
<li><strong>email</strong> - For security, hidden by default on all users except the current user.</li>
<li><strong>password</strong> - Never readable under any circumstances. Can only be set when the user is logged in, when creating a new user, or from the Dashboard.</li>
</ul>
<h2>Registering a user</h2>
<p>First create a user by POSTing it to the root of the collection.
For this example our collection will be called <code>/users</code>.</p>
<pre><code>POST /users/login
Content-Type: application/json
{
"email": "foo@bar.com",
"password": "barfoo"
}
</code></pre>
<h2>Authenticating a user</h2>
<p>To login a user, send a POST request to <code>/&lt;collection name&gt;/login</code>:</p>
<pre><code>POST /users/login
Content-Type: application/json
{
"email": "foo@bar.com",
"password": "barfoo"
}
</code></pre>
<p>The server will respond with the user, without the password.</p>
<pre><code>200 OK
{
"_id": "4f71fc7c2ba744786f000001",
"email": "foo@bar.com"
}
</code></pre>
<h2>Current user</h2>
<p>The currently logged in user is available by sending a GET request to <code>/users/me</code>.</p>
<pre><code>200 OK
{
"_id": "4f71fc7c2ba744786f000001",
"email": "foo@bar.com"
}
</code></pre>
<h2>Logging out</h2>
<p>To logout a user send a POST request to <code>/&lt;collection name&gt;/logout</code>:</p>
<pre><code>204 No Content
</code></pre>
