What is @prisma/internals?
@prisma/internals is a package that provides internal utilities and functions for working with Prisma, a modern database toolkit for TypeScript and Node.js. This package is typically used for advanced use cases and internal operations within the Prisma ecosystem.
What are @prisma/internals's main functionalities?
Engine Configuration
This feature allows you to retrieve the version of the Prisma engine being used. This can be useful for debugging and ensuring compatibility.
const { getEngineVersion } = require('@prisma/internals');
async function printEngineVersion() {
const version = await getEngineVersion();
console.log(`Prisma Engine Version: ${version}`);
}
printEngineVersion();
Schema Parsing
This feature allows you to parse a Prisma schema string into an internal representation. This can be useful for programmatically analyzing or modifying Prisma schemas.
const { parseSchema } = require('@prisma/internals');
const schema = `
model User {
id Int @id @default(autoincrement())
name String
}`;
async function parsePrismaSchema() {
const parsedSchema = await parseSchema(schema);
console.log(parsedSchema);
}
parsePrismaSchema();
DMMF (Data Model Meta Format) Generation
This feature allows you to generate the Data Model Meta Format (DMMF) from a Prisma schema. DMMF is a JSON representation of the Prisma schema, which can be used for various advanced use cases.
const { getDMMF } = require('@prisma/internals');
const schema = `
model User {
id Int @id @default(autoincrement())
name String
}`;
async function generateDMMF() {
const dmmf = await getDMMF({ datamodel: schema });
console.log(JSON.stringify(dmmf, null, 2));
}
generateDMMF();
Other packages similar to @prisma/internals
knex
Knex.js is a SQL query builder for Node.js that supports multiple database types. It provides a more general-purpose query building and schema management functionality compared to the more Prisma-specific utilities in @prisma/internals.
sequelize
Sequelize is a promise-based Node.js ORM for Postgres, MySQL, MariaDB, SQLite, and Microsoft SQL Server. It offers a higher-level abstraction for database operations, whereas @prisma/internals provides lower-level utilities specific to Prisma.
typeorm
TypeORM is an ORM for TypeScript and JavaScript (ES7, ES6, ES5). It supports multiple database types and provides a comprehensive set of features for database management. TypeORM is more focused on ORM capabilities, while @prisma/internals offers internal utilities for Prisma.
