Quick repo to demonstrate how one might include just the TCString decoder in their project.

This provides a lightweight version of just the IAB's decoder:

https://github.com/InteractiveAdvertisingBureau/iabtcf-es/tree/master/modules/core#installation

This specific repo leverages npm with webpack to bundle just the required libraries to decode an IAB TCF v2 string.

The output will be a lightweight minified JS file that you can plug in locally, or use however you like.

You can choose to bundle the TCF library yourself if you like if you already leverage webpack or an equivalent today.

• Node.js (tested with v18.11.0)
• NPM (tested with 8.19.2)

1. Clone this repo. git clone https://github.com/foreza/iab-tcf-decoder-built
2. Install node packages (webpack + iab tcf core). npm install
3. Run webpack. npx webpack --mode production

Output: this produces TCStringDecoder.js in the /dist folder.

Here is an example.

• Include TCStringDecoder.js as a standalone script.
• Use TCString.decode(<your tcf iab string>) - it'll output an TCModel object.
• Parse the TCModel for whatever you need.

• Here is the full decoder example provided by the IAB.
• Here is the IAB's repository, which includes the source code for the decoder.
