• Server

  • Elastic search from Docker container
  • Express JS

• Client

  • Vue (sorta)

• Data

  • city list in /Data directory

Requirements

• Docker
• Node.js (this sample tested with 10.x)
• Git

Get Code

• Clone or download this repository
  • git clone https://github.com/diberry/elastic-search-express
• cd elastic-search-express - move into directory just created
• npm install to install dependencies

Start ElasticSearch as local docker container

If you don't have an ElasticSearch server yet, you can use it from a Docker container.

• docker pull docker.elastic.co/elasticsearch/elasticsearch:7.8.1 to bring image down to local computer
• docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.8.1 to start container
• docker ps to see if container is running

Verify ElasticSearch is running with cURL CLI

• curl -X GET "localhost:9200/_cat/nodes?v&pretty"

Load city list into index

This is a one-time action to load city list into ElasticSearch index.

• npm run load_data

Build website code

• npm run prebuild to prep directories
• npm run build to transpile typescript into javascript into /dist folder

Run website code

• npm run open to open browser to http://localhost:3001
• npm run start

Run process over and over

• npm run start:all:again - assumes data is loaded and you just need to prebuilt, build, start, and open in browser

Website queries

• http://localhost:3001/?search=a - all cities beginning with the letter a

Known issues

When you query, there is no visual indicator blocking UI - just wait...
