elasticgraph-local

ElasticGraph::Local

Provides support for developing and running ElasticGraph applications locally. These locally running ElasticGraph applications use 100% fake generated data so as not to require a publisher of real data to be implemented.

Installation

elasticgraph-local is added to a project automatically when you bootstrap a project using:

gem exec elasticgraph new path/to/project

Usage

Everything you need is provided by rake tasks. Run the following to see what they are:

bundle exec rake -T

At a high level, this provides tasks that help you to:

• Boot Elasticsearch/OpenSearch (+ their corresponding dashboards) locally using the opensearch:*/elasticsearch:* tasks.
• Generate and validate ElasticGraph schema artifacts using the schema_artifacts:* tasks.
• Configure your locally running Elasticsearch/OpenSearch using the clusters:configure:perform task.
• Index fake data into Elasticsearch/OpenSearch (either running locally or on AWS) using the index_fake_data:* tasks.
• Boot the ElasticGraph GraphQL endpoint and GraphiQL in-browser UI using the boot_graphiql task.

If you just want to boot ElasticGraph locally without worrying about any of the details, run:

bundle exec rake boot_locally

That sequences each of the other tasks so that, with a single command, you can go from nothing to a locally running ElasticGraph instance with data that you can query from your browser.

Managing Elasticsearch/Opensearch

The opensearch:/elasticsearch: tasks will boot the desired Elasticsearch or OpenSearch version using docker along with the corresponding dashboards (Kibana for Elasticsearch, OpenSearch Dashboards for OpenSearch). You can use either the :boot or :daemon tasks:

• The :boot task will keep Elasticsearch/Opensearch in the foreground, allowing you to see the logs.
• The :daemon task runs Elasticsearch/Opensearch as a background daemon task. Notably, it waits to return until Elasticsearch/Opensearch are ready to receive traffic.

If you use a :daemon task, you can later use the corresponding :halt task to stop the daemon.
