fn-recommend

Fn Project demo in Java implements a recommendation engine mock.

Use case

You can get travel recommendation for a particular traveller based on age, destination and month of travelling.

Implementation

  • uses Jackson marshalling for JSON parameter (Traveller.java)
  • can be deployed on remote Fn as shown here on munz & more blog

Test Data

Test data is provided in ./testdata

e.g. use the following command to call the recommendation engine:

curl -X POST --data @testdata/syd.json localhost:8080/r/advtravel/recommend

Recommended Demo

Preparation

remote

fn apps d advtravel
fn start

local

docker login DOCKER_ID  
export FN_REGISTRY=DOCKER_ID  
export FN_API_URL=http://microservices.click:8080
fn deploy --app advtravel  

Live Demo Local Side

show local app (or deploy first)


fn apps list
[fn deploy --app advtravel --local]
fn apps l

show route

fn routes list advtravel

show logic and data

cd src/main/java/com/munzandmore/fn/
grep handle *.java
cat Traveller.java

test with curl or Postman

curl -X POST --data @testdata/xyz.json localhost:8080/r/advtravel/recommend

Live Demo Remote Side

fn apps c advtravel 
fn routes l advtravel
fn routes c advtravel /fn-recommend recommend:0.0.31

Then test from local curl
