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  ie: when data outdated, response last data, start bg task to update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
