Asterism, the best friend of Lyra

Today was released the first stable version of Asterism. Asterism provides a CLI to manage your Lyra instances and searches in a simple way.

What is Lyra? #

Lyra is a search engine created by Michele Riva. Lyra makes thousands searches within a few microseconds (μs) (yes, ms / 1000).

The main idea of Lyra is to provide a search engine that can be used in all devices that JavaScript can run: web, mobile, desktop, TVs, etc. Everywhere!

Ok, but what is Asterism? #

Asterism is a CLI tool that helps you to convert your database instances (MySQL and PostgreSQL) into Lyra instances and to create searches in a simple way.

How to install it? #

You can install Asterism using npm|yarn|pnpm:

npm install -g @mateonunez/asterism

How to use it? #

Asterism provides a simple CLI to manage your Lyra instances and searches.

Create a new Lyra instance #

To create a new Lyra instance you can use the migrate command:

asterism migrate postgres -d postgres -t posts

This command will create a new Lyra instance from a PostgreSQL table. You can also use the mysql option to create a new Lyra instance from a MySQL table.

A new persistent Lyra instance will be created in the provided folder. (default is /out).

Make a search #

To make a search you can use the search command:

asterism search "cool"

This command will search the provided string in all the Lyra instances and will return the results.

Example:

$ asterism search "cool"
