- Spell-check is implemented using an external API hence sometimes results can be slow, and sometimes results are not guaranteed to arrive. (Handled by sending multiple word queries to the API. Restricted by the limit of query parameter length)
- Crawling can hog memory since it has to
GETthe web-page. (Handled by enforcing a limit on the number of links per page) - Words for the spell check are derived from the
.text()property of the DOM. If the words on the page are created dynamically or are populated in a non-static approach, the words will also consist of HTML and Javascript keywords which are not handled while parsing.
Ports are opened for duplex communication and message passing.
popup.js has a port connection with background.js.
content.js has a port connection with background.js to pass messages to popup.
The button on popup will trigger the crawl and spell check on content. The whole architecture is asynchronus and the result table in the popup will be dynamically populated when the results arrive from the API.
