redis-memory-server/scripts/postinstall.js

Redis Server for testing. The server will allow you to connect your favorite client library to the Redis Server and run parallel integration tests isolated from each other.

/* eslint @typescript-eslint/no-require-imports: 0 */

/*
This script is used as postinstall hook.

When you install redis-memory-server package
npm or yarn downloads and compiles the latest version of redis binaries.

It helps to skip timeout setup `jest.setTimeout(600000);`
when first test run hits Redis binary downloading to the cache.
