Configuration in RESTApps
Page content
config/
RESTApp configuration files are stored in the config folder.
- src/
- config/
- index.html
- index.js (since 5.0)
- config.js
- config.css
- config/
Configuration is retrieved in a RESTApp server side context through the appData-object.
index.js [@since 5.0]
index.js enables route configuration and template rendering with a context. The concept is very similar to the app's regular index.js. Given that, Sitevision's Public API can be accessed, while browser objects cannot. A requester is available in the config's client context to fetch data client side.
Rendering index.html with a context
App configuration is rendered from the root route ('/'). Data passed to the render function on the response
object will be available as context when index.html is rendered. It will be evaluated, just like any other WebApp template, as an underscore template. Note that index.html is the only template that will be rendered, regular WebApp components are not available in the configuration view.
If no index.js is present it will be rendered as is.
Below is an example of how one might get data from Sitevision's Public API and expose it to index.html.
// index.js
(function() {
const router = require('router');
const portletContextUtil = require('PortletContextUtil');
const properties = require('Properties');
const appInfo = require('appInfo');
router.get('/', (req, res) => {
const currentUserEmail = properties.get(portletContextUtil.getCurrentUser(), 'mail');
const appName = appInfo.appName;
res.render({
currentUserEmail: currentUserEmail,
appName: appName
});
});
})();
// index.html
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title">Configure <%- appName %></h3>
</div>
<div class="panel-body">
<div class="form-group">
<label>Send reports to</label>
<input class="form-control" type="email" value="<%- currentUserEmail %>">
</div>
</div>
</div>
Below is another example of how to utilize Requester to fetch data from an external API and make it available in the configuration.
// config/index.js
(function() {
const router = require('router');
const requester = require('Requester');
router.get('/', (req, res) => {
requester
.get('https://jsonplaceholder.typicode.com/posts')
.done(data => res.render({ posts: data }));
});
})();
// config/index.html
<div class="form-group">
<label>Font</label>
<select>
<% _.each(posts, function(post) { %>
<option value="<%- post.id %>">
<%- post.title %>
</option>
<% }) %>
</select>
</div>
Response object (res)
The response object provides the following methods in the configuration view.
res.render(data)
Renders the index.html of the configuration. The data will be the context when the template is rendered.
res.send(data)
Default data type is json. For other cases dataType must be explicitly set in the request.
Request object (req)
The request object is identical to the request object in the app's regular index.js.
Require
Objects available via the require function.
// Server context, e.g. config/index.js
var
_ = require('underscore'), // [example](https://underscorejs.org/)
router = require('router'), // [example](/docs/webapps/index.js#h-Routing)
i18n = require('i18n'), // [example](/docs/webapps/i18n)
appInfo = require('appInfo'), // since 4.5.3 [example](/docs/webapps/require/appinfo)
storage = require('storage'), // since 5.0
appData = require('appData'), // since 5.2 [example](/docs/webapps/configuration/appdata)
appResource = require('appResource'), // since 5.2 [example](/docs/rest-api/restapps/resource)
myServerModule = require('/module/nameOfModule'); // [example](/docs/rest-api/restapps/module)
index.html
index.html defines your RESTApp configuration. index.html is stored in the /config folder.
If an index.js (available since 5.0) file is present index.html will be rendered as an underscore template.
If there is no index.js file index.html will be rendered as plain html.
Below is an example of a basic index.html.
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title">RESTApp Configuration</h3>
</div>
<div class="panel-body">
<div class="form-group">
<input class="form-control" placeholder="Select Page"
data-component="page-selector" name="page">
</div>
<div class="form-group">
<label>Text</label>
<input class="form-control" name="text">
</div>
</div>
</div>
Checkbox boolean
For checkboxes, use the data attribute data-value-type="boolean"
to make it return a true or false value.
Sitevision components
Sitevision offers "native" components to select values from the Sitevision model. Values are retrieved using the appData-object in a server side script context.
In order to utilize Sitevision components, simply add data-component="<type>"
to an input/select element. The following types are supported.
// page-selector
<input class="form-control" data-component="page-selector" name="page">

HTML Components
Regular HTML elements may also be used to accept data from the user.
AppData
Configuration is accessed server side using appData.
i18n
The i18n function is available when rendering if the index.html file is evaluated as an underscore template, i.e. when an index.js file is present.
The app's default language bundles will be used.
// config/index.html
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title"><%= i18n('settings') %></h3>
</div>
<div class="panel-body">
<div class="form-group">
<label><%= i18n('pickStartPage') %></label>
<input class="form-control" data-component="page-selector" name="page">
</div>
</div>
</div>
// i18n/en.json
{
"settings": "Settings",
"pickStartPage": "Select a start page"
}
The i18n function is also available server side in index.js (and server modules).
var
i18n = require('i18n'),
localizedName,
...
localizedName = i18n.get('name');
...
config.js
In config.js, custom client JavaScript may be added, that will be executed in the configuration panel. It is also possible to overwrite default functions (validate
, setValues
and getValues
).
Validate
By default, elements with the required
attribute are validated. To add custom validation, overwrite the default validation function.
(function() {
// overwrite default validate function
window.validate = function() {
var emailInput = document.querySelector('input[name=email]');
return isValidEmail(emailInput.value);
};
}());
setValues
setValues
populates elements with data when configuration is loaded. To handle custom components this function should be overridden.
(function($) {
// populate inputs when configuration is loaded
window.setValues = function(values) {
var inputs = document.querySelectorAll('input');
inputs.forEach(function(input) {
var name = input.name;
if (name) {
var value = values && values[name],
$input = $(input);
$input.val(value);
$input.trigger('change');
}
});
};
}(jQuery));
getValues
getValues
retrieves values from elements that will be sent to the server. To handle custom components this function should be overridden.
(function($) {
// retrieve values that will be sent to the server
window.getValues = function() {
var values = {},
inputs = document.querySelectorAll('input');
inputs.forEach(function(input) {
var name = input.name;
if (name) {
var inputValue = input.value;
values[name] = inputValue;
}
});
return values;
};
}(jQuery));
Client requester [@since 5.0]
A client requester is available on the window object in the config's client context (i.e. config/config.js). Utilize the requester to perform requests to routes specified in config/index.js.
The requester is similar to the client requester available in the WebApp SDK. What differs is that instead of specifying a url, a route is specified.
Default response data type is json. For other cases dataType must be explicitly set in the request.
Below is an example of how to call a route ('/test') defined in config/index.js from the config's client context.
// config/index.js
router.get('/test', (req, res) => {
res.json({
value: 'Hello from /test'
});
});
// config/config.js
$(function () {
$('button').on('click', function () {
requester.doGet({
route: '/test',
data: {
value: $('[data-value]').val()
}
}).done(function (res) {
$('#fetched-data').text(res.value);
});
});
});
config.css
Add custom CSS for the configuration panel.
// index.html
<div class="form-group">
<label>Text</label>
<input class="form-control amazing-class" name="text">
</div>
// config.css
.amazing-class {
color: blue;
}
SiteVision node types
Refer to the node types documentation to see what properties are available for different node types. Values retrieved from appData.get()
are JavaScript compatible.
- PropertyType.DATE returns a timestamp
- PropertyType.WEAKREFERENCE returns an ID
Config Example App
A WebApp demonstrating configuration is available in Sitevision's GitHub repository.
