MariaDB

MariaDB is a fork of MySQL, created to maintain MySQL’s features while ensuring open-source development. It can be connected using the same way as MySql with Prisma plugin.

Pre-requisites​

In order to use MariaDB database you need:

  1. an existing godspeed project with “prisma-as-datastore plugin” installed
  2. a MariaDB database server running
  3. and database connection URL

CONNECTION_URL​

mariadb://USER:PASSWORD@HOST:PORT/DATABASE

Setting Environment Variable​

You have to define the database connection url as an environment variable in .env as :

DATABASE_URL="mariadb://USER:PASSWORD@HOST:PORT/DATABASE"

And then this environment variable is provided in the url field of the datasource block in your prisma schema. src/datasources/mariaDB.prisma

datasource db {
  provider = "mariaDB"
  url      = env("DATABASE_URL") 
}
Sample prisma schema for mariaDB database 
datasource db {
  provider = "mariaDB"
  url      = env("DATABASE_URL")
}
generator client {
  provider = "prisma-client-js"
  output = "./prisma-clients/mariaDB"
  previewFeatures = ["metrics"]
}

model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  name  String?
  posts Post[]
}

model Post {
  id        Int     @id @default(autoincrement())
  title     String
  content   String?
  published Boolean @default(false)
  author    User    @relation(fields: [authorId], references: [id])
  authorId  Int
}

Generate prisma client​

godspeed prisma prepare

This command will generate the prisma client and will sync the database with prisma schema

Generate CRUD APIs​

Then You can generate the CRUD API'S by entering the below command:

godspeed gen-crud-api

  • This command will generate the crud apis based on the sample prisma schema provided at ./src/datasources/mariaDB.prisma

  • Now you can view the event and functions according to the defined prisma schema
