Overview

The Prisma constructor is used to create new instances of the Prisma client.

constructor(options: BasePrismaOptions)

BasePrismaOptions has the following properties (all are optional):

endpoint: string: The endpoint of your Prisma service. If not provided, the Client will default to the endpoint that was specified in prisma.yml when the Client was generated.
secret: string: The secret protecting the API of your Prisma service. If not provided, the Client will default to the secret that was specified in prisma.yml when the Client was generated.
debug: boolean: If set to true, each invokation of a method on the Prisma client will print the GraphQL query that is sent to the Prisma API to the console. Default: false.
fragmentReplacements: FragmentReplacement[]: A list of GraphQL fragments that will be applied to each query/mutation/subscription sent to the Prisma API.

Use default values for endpoint and secret that were specified in prisma.yml when the Client was generated:

const prisma = new Prisma({})

Override default values for endpoint and secret that had been specified in prisma.yml when the Client was generated:

const prisma = new Prisma({ 
  endpoint: "http://localhost:4466/hello-world/dev",
  secret: "mysecret42",
})
