Strongloop Loopback connector for Elasticsearch
Do you think you have a good background to be an active contributor either from features contributions perspective or from a code reviewer perspective?
If your answer is yes from a code reviewer perspective then please ask the loopback team to make you a direct contributor to the project. I do not have such a privilege.

An overview on updates in https://github.com/bharathkontham/loopback-connector-elastic-search
- Only Elasticsearch 6.x is supported, ES 5.x or older version may or may not work.
- Currently only one Index can be configured in one ES datasource of loopback (working on multiple indices configuration support) but we can use same datasource multiple loopback models.
- A keyword field "docType" is used to store model names which provides support to use same Mapping Type of a single index for storing multiple models. This is major change in connector as earlier version used different mapping types to store different loopback models.
- Nested objects querying (array of objects type in loopback), geo spatial queries and like, nlike are supported.
I'll update examples and documentation soon.
I'm working only on ElasticSearch 6.x or later support (no intention to work on older versions)
Sample query for nested objects and geo_spatial:
{
"where": {
"and": [
{
"address.geo": {
"geo_shape": {
"address.geo": {
"shape": {
"type": "circle",
"coordinates": [
78.38214860577659,
17.44064909837838
],
"radius": "1km"
},
"relation": "within"
}
}
}
},
{
"entity_properties.value": {
"gt": 50
}
}
]
}
}
entity_properties is a nested object and address is an object.
address.geo has geo_shape data.
Updated example for Elasticsearch 6.x in https://github.com/bharathkontham/loopback-connector-elastic-search
Please check examples/server/datasources.sample-es-6.js
@bharathkontham - would you like to be added as a contributor to the strongloop community repo so that you can own and release 6.x related work more quickly?
Since you will only focus on 6.x and I cannot just nuke the other versions ... We can create a branch for 6.x development and perform 6.x releases from it or I am open to other ideas too.
Let us know.
@bharathkontham - we are hosting a meetup on Elasticsearch and loopback in Pune India. Tentatively it’s planned for sometime between March 2nd and March 14th.
I would like to invite you to attend as a speaker and present and talk about whatever you want on these topics.
The Airfair to fly from Hyderabad to pune and back will be at no cost to you.
