oAds

This is an Origami module that enables advertising from Google's DFP Ad Server (part of Ad Manager), and provides customised demographic, behavioural (via Krux), and contextual (via Admantx) targeting.

Requirements

For basic use, a DFP (DoubleClick for Publishers) account with Google is required. Each targeting/tracking supplier will require their own configuration and setup.

Demos

Demos for all ads currently served across ft.com are available in the Origami Registry.

Documentation

Includes detailed installation and set-up instructions, along with details about the module.

To build the documentation locally, from the docs directory, run:

bundle install
jekyll build

It will generate a _site directory where generated site will be compiled You can then run the jekyll local server by executing jekyll serve.

Developing

Install & Demos

• To install: obt install.
• To run the demos: obt demo.
• To run a demo server: npm run demo-server

Tests

See the test documentation

Releasing

You will need a GITHUB_TOKEN environment variable with access to the repository in your .env file Get a github token with "repo" access and make it accessible as an environment variable.

Run npm run release (patch|minor|major|x.y.z) in master then follow the interactive steps.

This will bump version numbers in the source and commit them, push to github and create a new release.

The command uses release-it under the hood as well as genversion to automatically bump version numbers in the source.

Migration Guide

Upgrading to v14

This release does not change any o-ads behaviour however it now uses the latest major versions of all Origami sub-dependencies.

The following origami dependencies were updated: o-colors,o-visual-effects, o-viewport, o-grid, ftdomdelegate

Some CSS properties needed to be updated in order to work with the updated down-stream dependancies.

We have also added document.visibilityState to the Origami Required BrowserFeatures list as the polyfill for this feature was removed from the latest version of o-viewport.

Upgrading to v13

This release removes integration with Krux for behavioural targeting. The origami component o-permutive can be used for behavioural tracking instead.

Upgrading to v12

This release introduces the following changes:

1. o-ads is now recording a performance mark for every event that it dispatches. The performance mark will have the same name as the event that originated it plus, in some cases, a suffix that helps determine the circumstances that triggered the event. This is all being used internally by o-ads to provide new metrics functionality.

2. o-ads exposes a new setupMetrics method that simplifies obtaining performance metrics. setupMetrics accepts two parameters:

• An array of objects containing the configuration of the different metrics that need to be tracked.
• A callback function to be called whenever any of the trigger events of any of those configuration objects is dispatched.

1. Several custom events fired by o-ads have been renamed for different reasons. This is the list of events whose name has changed:

Old event name	New event name
startInitialisation	initialising
moatIVTcomplete	IVTComplete
apiRequestsComplete	adsAPIComplete
adServerLoadSuccess	serverScriptLoaded
ready	slotReady
render	slotCanRender
gptDisplay	slotGoRender
rendered	slotRenderStart
complete	slotExpand
adIframeLoaded	slotRenderEnded

A guide can to the new names can also be found in this two diagrams:

Event renaming pt. 2

Upgrading to v11

As of version 11, o-ads has been updated to use ES modules. Unfortunately, this means it is not backwards compatible with CJS modules and clients cannot require('o-ads') anymore.

• Breaking change: if importing o-ads in your build, you must now do it as follows: import oAds from 'o-ads'

Upgrading to v10

• Breaking change: o-ads now defaults to never collapsing empty ads slots following google gpt behavior.
• Breaking change: collapsing config oAds takes 3 possible options for the collapseEmpty attribute: 'before', 'after', 'never' and defaults to 'never'
• Breaking change: collapsing ads for a specific slot on the markup now uses 'before', 'after', 'never' instead of true and false previously
• Breaking change: Global collapse empty behavior is set in config.collapseEmpty instead of config.gpt.collapseEmpty previously

Upgrading to v9

• Breaking change: o-ads now requires consent before loading Krux or adding custom targeting to the ad calls. Consent can be provided in two ways:

1. Provide a cookie with the name FTConsent and specify which consent the user has given as part of the value like this: behaviouraladsOnsite:on,programmaticadsOnsite:on
2. Initialise o-ads with the disableConsentCookie option.

Upgrading to v8

• Breaking change: If you use the destroy method on a slots instance, this will now properly destroy the given slots rather than just clear them
• New feature: util event 'off' - remove an event listener
