intro

  • 2 README.md in 2 projects, but this doc is the main (more coverage)
  • serve http request with hackernews posts
    api definition refer: src/index.ts
  • most business (difficult) logic in services classes in service folder

run

install

npm i

TODO may need resolve vulnerabilities

start

npm start

ENHANCE

  • failover, "must do" but no time:
    • http handler, only notify error, frontend may retry
    • app service, may have "service-side retry" by conditions
  • data (class & graphql schema) duplicated /w frontend,
    can use shared project
  • filter & sort can be in frontend?
  • http get data from hacker news should background task,
    ie: when data outdated, response last data, start bg task to update

BONUS thought

  • paging by scroll

    • each page 10 items, together with the filtering feature,
      may get many page from hacker news (eg: >100 comments)
    • the difficult part is frontend, only need time to do

  • react native

    • only need time to do
