The timeline follow-back is a method for retrospectively ascertaining recent alcohol and other drug use patterns developed by Linda C. and Mark B. Sobell. This web-based timeline form was developed for the MGH Center for Addiction Medicine and is designed for use with REDCap databases in clinical research.

A major revision in Typescript was completed in 2024 by Ivy Zhu. The original application was developed by Michael Pascale.

Download and copy the following libraries to the static/ directory.

• bulma.min.css (Bulma v0.9.4)
• fonts/material-icons.css (Material Design Icons v7.0.96)

You'll also need to install Node.js which provides npm (Node Package Manager). You'll need this to install TypeScript and Webpack.

On MacOS, the easist way to install Node is with brew (Homebrew). Alternatively, you can use nvm (Node Version Manager).

brew install node@18

Using npm, we can now automatically install all the packages listed in package.json.

npm install

The application consists of what you see in index.html and the TypeScript under src/.

We won't be using the TypeScript compiler tsc directly. Instead, Webpack will compile and then bundle all of our code into a single JavaScript file under static/tlfb-v3-bundle.js.

webpack-dev-server provides hot reload each time you save a TypeScript file. See the head of index.html to correct the path, then run webpack.

npx webpack serve

This will start the development server, and you should be able to open the webpage by going tolocalhost:8080 in your web browser.

See the head of index.html to correct the script paths, then run webpack.

npx webpack

This will create the final bundle under static/tlfb-v3-bundle.js.

Simply copy index.html and the static/ directory onto your production webserver.
