Disk Persistence Plugin

Experimental stage, use at your own risk.

Installation

npm i @lyrasearch/plugin-disk-persistence

yarn add @lyrasearch/plugin-disk-persistence

pnpm add @lyrasearch/plugin-disk-persistence

Usage

You can save and restore a database by using the methods exposed by the plugin-disk-persistence package.

Given the following database:

import { create, insert } from '@nearform/lyra'

const myPrimaryDB = create({
  schema: {
    quote: 'string',
    author: 'string'
  }
})

insert(myPrimaryDB, {
  quote: 'Impossible is for the unwilling',
  author: 'John Keats'
})

insert(myPrimaryDB, {
  quote: 'I have not failed. I’ve just found 10,000 ways that won’t work.',
  author: 'Thomas A. Edison'
})

you can save the database to disk:

import { persist } from '@lyrasearch/plugin-disk-persistence'

persist(myPrimaryDB, 'binary')

Available formats are:

• binary: saves the database to a compressed, binary file using dpack algorithm (recommended)
• json: saves the database to a JSON file

The persist function accepts as a third argument the file name. When no argument, a default name will be used: lyra_bump_623432432.

Note: you can use the environment variable LYRA_DB_NAME to override the default name.

At this point, you can also restore the database from disk:

import { search } from '@nearform/lyra'
import { restore } from '@lyrasearch/plugin-disk-persistence'

const mySecondaryDB = restore('binary')

search(mySecondaryDB, {
  term: 'work'
})
