This adapter supports all methods (create
, delete
, update
, patch
, find
, get
) and the common way for querying (equality
, $limit
, $skip
, $sort
, $select
, $in
, $nin
, $lt
, $lte
, $gt
, $gte
, $ne
, $or
, $and
). Also supports eager loading ($eager
), full-text search ($search
) and prisma filtering (from 0.7.0 on with $prisma
, previously with $rawWhere
which is now deprecated).
Prisma Version
- Prisma v3 use
feathers-prisma
v0.6.0 - Prisma v5 use
feathers-prisma
v0.7.0 or higher
Setup
import feathers from "@feathersjs/feathers";
import { service } from "feathers-prisma";
import { PrismaClient } from "@prisma/client";
// Initialize the application
const app = feathers();
// Initialize the plugin
const prismaClient = new PrismaClient();
prismaClient.$connect();
app.set("prisma", prismaClient);
const paginate = {
default: 10,
max: 50,
};
app.use(
"/messages",
service(
{
model: "messages",
paginate,
multi: ["create", "patch", "remove"],
whitelist: ["$eager"],
},
prismaClient
)
);
Eager Loading / Relation Queries
Relations can be resolved via $eager
property in your query. It supports also deep relations. The $eager
property has to be set in the whitelist
option parameter. Otherwise the service will throw an error.
app.use(
"/messages",
service(
{
model: "message",
whitelist: ["$eager"],
},
prismaClient
)
);
// will load the recipients with the related user
// as well as all attachments of the messages
app.service("messages").find({
query: {
$eager: [["recipients", ["user"]], "attachments"],
},
});
// selecting specific fields is also supported since 0.4.0
app.service("messages").find({
query: {
$eager: {
recipients: ["receivedAt", "user"],
},
},
});
Filter with default prisma filters
Since 0.5.0 it is possible to use default prisma filters. This makes it possible to filter JSON fields or to filter relations.
The $prisma
property has to be set in the whitelist
option parameter. Otherwise the service will throw an error.
Since 0.7.0 use the $prisma property to filter instead of using the $rawWhere property.
app.use(
"/messages",
service(
{
model: "message",
whitelist: ["$prisma"],
},
prismaClient
)
);
// will load all messages where at least one of the recipients userIds is equal 1
app.service("messages").find({
query: {
recipients: {
$prisma: {
some: {
userId: 1,
},
},
},
},
});
Batch requests
This adapter supports batch requests. This is possible by allowing this in the multi
property in the service options. Supported methods are create
, patch
and delete
.
app.use(
"/messages",
service(
{
model: "messages",
multi: ["create", "patch", "delete"],
},
prismaClient
)
);
app.service("messages").create([{ body: "Lorem" }, { body: "Ipsum" }]);
Full-Text Search
Prisma supports a full-text search which is currently in preview mode. Find out more how to activate it here. If you activated it through your schema you have to allow it in the whitelist
property:
app.use(
"/messages",
service(
{
model: "messages",
whitelist: ["$search"],
},
prismaClient
)
);
app.service("messages").find({
query: {
body: {
$search: "hello | hola",
},
},
});
Complete Example
Here's an example of a Feathers server that uses feathers-prisma
.
import feathers from "@feathersjs/feathers";
import { service } from "feathers-prisma";
// Initialize the application
const app = feathers();
// Initialize the plugin
const prismaClient = new PrismaClient();
prismaClient.$connect();
app.set("prisma", prismaClient);
const paginate = {
default: 10,
max: 50,
};
app.use(
"/messages",
service(
{
model: "messages",
paginate,
multi: ["create", "patch", "remove"],
whitelist: ["$eager"],
},
prismaClient
)
);
// Or if you want to extend the service class
import { PrismaService } from "feathers-prisma";
