Portal Setup
Learn what Portals are and how to set them up for your organization.
Portals require a separate license.

A Portal is an org with special privileges that serves two purposes. First, it provides a space for your organization to showcase projects with special data sets, tools that you’ve published, news and highlights or other important links. Second, the Portal has customized branding that will follow the end-user throughout the site with a curated view of projects and tools.
Portal Home

To configure a new Portal for your org you will work with the DNAnexus xVantage team. First, the Partner will need to specify the org that will host the Portal. The Portal is tied to exactly one org.
We will ask you to provide the initial configuration requirements and assets (logos or other images, brand colors, text, and links) listed below.
Once all configuration requirements and assets have been provided, the Portal will be ready to test. At this point the xVantage team will provide a link to the Portal along with a brief training to orient the Org Admin to using the portal.

This section describes configurations that the Org Admin can make by editing and uploading new .json files or new images.

  • Logo (no size limit, but it’s recommended to stay under 200px high)
  • (Optional) Login button color; must be conducive to white text
  • (Optional) Whether to hide the registration link
  • (Optional) Text to display under login button

  • Logo (max 100x100px)
  • (Optional) Register button color; must be conducive to white text
  • (Optional) Can disable registration page, redirecting directly back to login
  • (Optional) Markdown text to display under register buttons
  • (Optional) Add default region for users who register with this page
  • (Optional) Add short sentence indicating terms of acceptance

The branding.json controls the colors in the Header. The navigation.json controls the navigation links and menus (with the exception of the logo navigation).
These are the items you can configure:
  • Header corner Logo (min 15x15px, max 50x30px)
  • (Optional) Logo link destination, defaults to Home page (configure in the branding.json file)
  • (Optional) Whether the logo link opens in a new tab (configure in the branding.json file)
  • (Optional) Support page (used when the user clicks on “Get Help” in the Help menu, default is DNAnexus Support Form)
  • (Optional) Color for the nav underbar, text, background, nav hover background color, landing page button color and color array for the user bubble. Currently icons do NOT change color, so do not make the background bar a dark color or text will not be visible.
  • (Optional) Navigation customization. You can add custom items to the ends of our Projects, Tools, and Help menus, remove those menus entirely, or add new menus and links to the nav header.
Example of adding items to the Tools menu
Example of adding extra navigational links or menus. Also shows recoloring text and highlight.
  • (Optional) Filters for the projects list (i.e. when the user clicks on “All Projects” in the Projects menu)
  • (Optional) Whether to hide the community switcher (this will “lock” the user into the current community)

The main page is a customizable landing page with the ability to showcase in any order with any amount of widgets:
  • Specific projects
  • Specific tools
  • Links to external websites
  • Images (PNG, JPEG, TIFF, BMP, etc)
  • Markdown text
The home.json file contains a list of widgets to display, and the order in which to display them.
Available widgets:
Text widget:
  • Title
  • id property of “markdown”
  • Minimum width
  • Markdown text
Image widget:
  • Minimum width
  • id property of “image”
  • Image resource or location (image can be any type, e.g. PNG, JPEG, TIFF, BMP)
  • Alt text (when image can’t be displayed)
Link list widget:
  • Title
  • id property of “link”
  • Minimum width
  • List of link destinations and their titles
Project list widget:
  • Title
  • id property of “project” or “projectCards”
  • Minimum width
  • Project filter criteria (based on the API for /system/findProjects)
  • Project sub-page destination
Tool list widget:
  • Title
  • id property of “tool”
  • Minimum width
  • Tool filter criteria (based on the API for /system/findApps)

Portal assets are stored with the json files. You can easily upload json and png files using the GUI on the main portal home page. The sections for each json file describe the access permissions that each file requires.
The UI can become disabled if a flawed json is inadvertently uploaded. Review the section below on how to validate json files.
File Upload

JSON (JavaScript Object Notation) is a lightweight data-interchange format. Most of the time, it is easy for humans to read and write but sometimes, it is extremely difficult to actually read and make sense of. We highly recommend validating your portal asset using tools such as jsonlint or jsonformatter, before using them to update the community portal.

It is mandatory to clear your browser cache after updating your portal assets with a revised JSON file.
In most browsers, you can clear the cache from the Privacy or History area in the Settings or Options menu, depending on the browser. The hotkey combination Ctrl+Shift+Del (or Cmd-Shift-Del on a Mac) works with most browsers as well.
While that hotkey combo works in most non-mobile browsers, the exact steps involved in clearing your browser's cache depend entirely on what web browser you're using. If these suggested steps do not work please refer to your browser’s documentation.
As an alternative to clearing your cache, it is possible to use ‘private’ browsing (a.k.a ‘privacy’ mode or ‘incognito’ mode) to view the asset updates. This is a privacy feature in some web browsers to disable browsing history and the web cache allowing a person to browse the Web without storing local data that could be retrieved at a later date. To launch your browser in ‘incognito’ mode, please refer to your browser's documentation.

DNAnexus can also provide you with CLI scripts to update your assets. This provides an alternative to the UI, which can become disabled if a flawed json is inadvertently uploaded. Contact [email protected] for more information and to request access to the scripts for CLI updating.

Portal assets are split into many different files, all loaded at different times by different components. Below are samples of each file. Note that several of these files contain references to images; for communities, you can either prepend a pound sign (#) to denote an image fetched from the community assets (e.g. “#logo.png” would fetch the file “logo.png” stored in the community), or you can use a normal URL to fetch an image from an external source.

This file must be public (viewable by all users) Applies to the header and community selector, as well as the login and registration pages. colors is optional in each section and contains information about how to change the colors of various elements in the given section.
Earlier versions of Portals had two additional files -- login.json and register.json' -- you do not need to remove those, but all of their information will need to be transferred to branding.json.
In the header, logoOpensNewTab is optional and if true will open a new tab when the user clicks on the logo in the upper left. hideCommunitySwitch is also optional and, if true, will hide the community selector in the upper left (essentially locking the user into the current community).
In the login and registration sections, logo specifies a logo to be used at the top of the given page and text can be Markdown which will be rendered at the bottom of the page (below the button but above the footer).
The registration section has several optional attributes. First, disable, which if true will hide the “Create Account” link on the login page and redirect the user to the login page if they try to manually visit the registration page. There’s also an optional agreeToText attribute, which will be a plain text string (not Markdown) with a checkbox which the user needs to agree to before they can register. It also has an optional region attribute which, if set, will force any user created with this login page to have the given default region instead of presenting them with an option.
homeURL and supportURL are optional and are the URLs used for the main community site (destination when clicking on the logo in the upper left) and support pages (destination when a user selects “Get Help” from the Help menu), respectively. description is shown in the community selector menu.
Note that any logo images defined here must be uploaded with public permissions--logos for the login and registration pages in particular will need to be downloaded by unauthenticated users.
