All the best places to go to when you are in the Twin Cities (for the Super Bowl).


The default gulp develop will not get new data from Airtable, nor will it create the responsive images. So, to make these things happen specifically, use the following:

  1. New data: gulp source:data
  2. Create responsive images: gulp assets:responsive:images, gulp assets:responsive:airtable
  3. Create responsive video images: gulp assets:responsive:videos

You should only have to run these when you have updated content.

In order to publish and build everything from scratch, run the following (note that it will take some time to run all this, specifically the publishing will take some time unless you have done it before on your computer):

  1. gulp deploy --production


Meta tag and "SEO" testing

See the following resources to test attributes.


The following are global prerequisites and may already be installed.

  1. (on Mac) Install homebrew.
  2. Install Node.js.
    • (on Mac) brew install node
  3. Install Gulp: npm install gulp -g
  4. Set the following environment variables:
    • AIRTABLE_API_KEY: The Airtable API key used to get data from the spreadsheets.
  5. Install ffmpeg
    • With Homebrew:
        brew tap varenc/ffmpeg && \
        brew tap-pin varenc/ffmpeg && \
        brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus;
        # This will install all extensions (probably not needed)
        brew install ffmpeg $(brew options ffmpeg | grep -v -e '\s' | grep -e '--with-\|--HEAD' | tr '\n' ' ');

The following should be performed for initial and each code update:

  1. Install Node dependencies: npm install


To run a local web server that will auto-reload with Browsersync, watch for file changes and re-build: gulp develop

Directories and files

  • config.json: Non-content config for application.
    • Use this to add non-local JS or CSS assets, such as from a CDN.
    • This can be overridden with a config.custom.json if there is a need to add configuration that should not be put into revision history.
  • content.json: See Content and copy. This file is used to hold content values, such as a site-wide title or description.
  • templates/: Holds HTML templates. Any files in here will get run through EJS templating and passed values from config.json, content.json, package.json, and data from the Airtable data source.
    • templates/layout.*.ejs.html: These are the files that get rendered with the data described above and correlate to a file or set of files rendered in the build.
    • templates/_*.ejs.html: These are includes used to help separate out and reuse parts.
  • styles/: Styles in SASS syntax.
    • styles/index.scss: Main point of entry for styles.
    • styles/_*.scss: Any includes should be prefixed with an underscore.
  • app/: Where JS logic goes. This supports ES6+ JS syntax with Babel and gets compiled with Webpack.
    • app/index.js: Main entry point of application.
    • app/svelte-components/*: Svelte components. These get rendered in the template/layout process as well as brought in on the client side.
  • assets/: Various media files. This gets copied directly to build.
  • sources/: Directory is for all non-data source material, such as wireframes or original images. Note that if there are materials that should not be made public, consider using Dropbox and make a note in this file about how to access.
  • lib/: Modules used in building or other non-data tasks.
  • tests/: Tests for app; see Testing section below.
  • The rest of the files are for building or meta-information about the project.

Content and copy

The majority of content is managed in this Airtable. Use the following command to get new data from the Airtable, saved as sources/guide-data.json:

gulp source:data

Note that the gulp develop process does not automatically download new data as it would be slow to run every time, which means you will have to manually run the above command.

Dependencies and modules

Depending on what libraries or dependencies you need to include there are a few different ways to get those into the project.

  • JS
    • Include it with npm.
      • For instance: npm install --save awesome-lib
      • This can then be included in the application, with something like:
        import awesome from "awesome-lib";
    • For dependencies that are very common and are available through a trusted CDN, you can include it in config.json. Consider using the StribLab static libs CDN.
      • For instance:
        "js": {
          "globals": [
      • In your application, make sure to add a comment like the following so that linters will know that the dependency is already loaded.
        /* global Pym */
      • IMPORTANT Make sure to always use a specific version from a CDN; do not use latest or something similar.
      • For testing, these need to be available and should be added to tests/global.js
    • For local modules that you have written yourself, you can use the ES6 module syntax.
      • For instance, say you have created a utils.js module file, just use a relative path to include it:
        import utilsFn from "./utils.js";
        let utils = utilsFn({});
  • CSS
    • Include it with npm.
      • For instance: npm install --save normalize-scss
      • This can then be included in the application, with something like:
        @import "normalize-scss/sass/_normalize.scss";
    • For dependencies that are very common and are available through a trusted CDN, you can include it in config.json. Consider using the StribLab static libs CDN.
      • For instance:
        "css": {
          "globals": [
      • IMPORTANT Make sure to always use a specific version from a CDN; do not use latest or something similar.


Testing is run via Jest. Fast, unit and higher level testing will happen on build. You can run these test manually with gulp js:test or npm test.

Acceptance testing (i.e. high level quality assurance) is done separately as running headless Chrome takes more than a couple seconds. You will need a new version of Chrome or Chrome Canary installed, then run js:test:acceptance.

NOTE: Acceptance test will fail until this fix is published.

TODO: Some basic automated, cross-browser testing would be very beneficial. Unfortunately things like Browserstack are very expensive, and managing our own servers to do this would be very expensive time-wise as well.

Embed testing

A manual test page is provided for looking at the piece embeded in another page.

  1. Assumes you are running the development server with gulp develop
  2. Run a local server for the test directory, such as cd tests && python -m SimpleHTTPServer or http-server ./tests/
  3. In a browser, go to http://localhost:8080/manual/embed.html.


All parts are compiled into the build/ folder. The default complete build can be done with gulp or gulp build

Publish and deploy

Deployment is setup for AWS S3. Set the following environment variables; they can be set in a .env file as well. For further reading on setting up access, see Configureing the JS-SDK.


To deploy, run gulp deploy. This will build and publish to the location configured as default (see Configuration below).

To deploy to the production location, for instance, simply use that flag like: gulp deploy --production

A handy command is to use gulp publish:open to open the URL to that project.


Publishing is configured in the config.json file. The publish property can have the following keys: default, testing, staging, and production. It is suggested to use default in place of the staging as the default gets used when no flag is specified (see below). Each key should correspond to an object with bucket, path, and url. IMPORTANT: The url should be a fully qualified URL that ends with a /. This URL will get inserted into some meta tags on the page by default. For example:

  "publish": {
    "default": {
      "bucket": "",
      "path": "news/projects-staging/all/super-bowl-guide/",
      "url": ""
    "production": {
      "bucket": "",
      "path": "news/projects/all/super-bowl-guide/",
      "url": ""

Using the flags --testing, --staging, or --production will switch context for any relevant publish or deploy commands. Note that if the flag is not configured, the default will be used.

Publishing token

The publishing function, uses a token that helps ensure a name collision with another project doesn't overwrite files unwittingly. The publishToken in config.json is used as an identifier. This gets deployed to S3 and then checked whenever publishing happens again. The gulp publish (run via gulp deploy) will automatically create this token if it doesn't exist.

If you see an error message that states that the tokens do not match, make sure that the location you are publishing to doesn't have a different project at it, or converse with teammates or administrators about the issue.

Styles and practices

Having a consistent style for code and similar aspects makes collaboration easier. Though there is nothing that enforces these things, intentionally so, spending some time to adhere to these styles will be beneficial in the long run.

  • JS: Javascript is linted with ESLint and defined in .eslintrc.
  • Styles: SASS (and CSS) is linted with stylelint and defined in .styleintrc.

Other good practices that are not encompassed with linters.

  • General
    • Comment as much as possible without being overly redundant.
  • JS
    • Use small modules as much as possible.
  • Styles
    • Use classes instead of ids for HTML elements, specifically for styling and JS.
    • Use relative units such as rem, em, vh, vw, or %, instead of absolute values such as px. This helps accessibility as well as designing for different screen sizes.
      • Overall, use rem for "component" level styling, such as a form, and then use em for styling inside components.
