Sticker making happens by opening html templates in Puppeteer, a headless Chrome and taking a screenshot. Most of this logic is in functions/makeSticker.js and templates are in functions/templates.

Specially during initial user testing, sometimes we want to upload a set of static images as stickers for a query. This is done using Python/cached_query_from_static.py.

The server endpoints are implemented in functions/index.js:

• /featured returns topic queries that we're currently user testing. (i.e. 2019 Women's World Cup)
• /query returns at least one type of results (i.e. newsArticle) for any query.
• /sticker returns a base64 sticker image via stickerId.
• /alternatives returns alternative designs of a certain sticker.

TODO:

• extend template.js with more types
