nextjs14, refinedev, graphql nestjs querry, mongodb

Hello I'm having trouble connecting Nextjs 14 Refine app with the mongo db backend. when creating the app I opted for nestjs querry. I've checked the documentation , but I'm a newbie and I don't find it easy to understand how to create the dataprovider with nestjs querry , graphql and mongodb. I followed the app CRM steps, but Next js with SSR and CSR adds a grade of difficulty for me 🙂 Really appreciate if someone could provide some guidance Many thanks

Hi @alex. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Sure, I can help guide you through setting up a Refine app with Next.js 14, using Nest.js Query, GraphQL, and MongoDB. Below are the steps to create a data provider and integrate it into your Next.js application. Step 1: Install Necessary Packages First, you need to install the required packages. You can do this by running the following commands:

npm i @refinedev/nestjs-query graphql-tag
npm i graphql-ws

npm i @refinedev/nestjs-query graphql-tag
npm i graphql-ws

Step 2: Create a GraphQL Client Next, create a GraphQL client with your API URL and pass it to the dataProvider function to create a data provider. In your app.tsx file, you can set it up as follows:

import Refine from "@refinedev/core";  
import dataProvider, { GraphQLClient } from "@refinedev/nestjs-query";  

const client = new GraphQLClient("<https://api.nestjs-query.refine.dev/graphql">);  

const App = () => (  
  <Refine  
    dataProvider={dataProvider(client)}  
  >  
    {/* ... */}  
  </Refine>  
);

import Refine from "@refinedev/core";  
import dataProvider, { GraphQLClient } from "@refinedev/nestjs-query";  

const client = new GraphQLClient("<https://api.nestjs-query.refine.dev/graphql">);  

const App = () => (  
  <Refine  
    dataProvider={dataProvider(client)}  
  >  
    {/* ... */}  
  </Refine>  
);

Step 3: Enable Realtime Features (Optional) If you want to enable realtime features using GraphQL subscriptions, you can set up a liveProvider as shown below:

import Refine from "@refinedev/core";  
import dataProvider, {  
  GraphQLClient,  
  liveProvider,  
} from "@refinedev/nestjs-query";  
import { createClient } from "graphql-ws";  

const client = new GraphQLClient("<https://api.nestjs-query.refine.dev/graphql">);  
const wsClient = createClient({  
  url: "wss://api.nestjs-query.refine.dev/graphql",  
});  

const App = () => (  
  <Refine  
    dataProvider={dataProvider(client)}  
    liveProvider={liveProvider(wsClient)}  
    options={{ liveMode: "auto" }}  
  >  
    {/* ... */}  
  </Refine>  
);

import Refine from "@refinedev/core";  
import dataProvider, {  
  GraphQLClient,  
  liveProvider,  
} from "@refinedev/nestjs-query";  
import { createClient } from "graphql-ws";  

const client = new GraphQLClient("<https://api.nestjs-query.refine.dev/graphql">);  
const wsClient = createClient({  
  url: "wss://api.nestjs-query.refine.dev/graphql",  
});  

const App = () => (  
  <Refine  
    dataProvider={dataProvider(client)}  
    liveProvider={liveProvider(wsClient)}  
    options={{ liveMode: "auto" }}  
  >  
    {/* ... */}  
  </Refine>  
);

Step 4: Run the Example Locally To see a working example, you can create a Refine app using the data-provider-nestjs-query example:

npm create refine-app@latest -- --example data-provider-nestjs-query

npm create refine-app@latest -- --example data-provider-nestjs-query

This command will set up a project with the necessary configurations and examples to help you get started. Additional Resources - Nest.js Query Documentation (https://doug-martin.github.io/nestjs-query/) - Refine Data Fetching Guide (https://refine.dev/docs/guides-concepts/data-fetching/) - Refine Realtime Guide (https://refine.dev/docs/guides-concepts/realtime/) By following these steps, you should be able to set up your Next.js 14 application with Refine, Nest.js Query, GraphQL, and MongoDB. If you encounter any issues, feel free to check the Refine documentation (https://refine.dev/docs/) or join the Refine Discord community (https://discord.gg/refine) for further assistance. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how should mongodb be set up with gql and nestjs querry?

kapa.ai•3w ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To set up MongoDB with GraphQL and Nest.js Query, you'll need to follow several steps to configure your backend properly. Below is a step-by-step guide to help you through the process. Step 1: Install Necessary Packages First, you need to install the required packages for MongoDB, GraphQL, and Nest.js Query:

npm install @nestjs/mongoose mongoose @nestjs/graphql @nestjs-query/query-graphql @nestjs-query/query-mongoose

npm install @nestjs/mongoose mongoose @nestjs/graphql @nestjs-query/query-graphql @nestjs-query/query-mongoose

Step 2: Configure MongoDB Connection In your app.module.ts file, configure the MongoDB connection using MongooseModule:

import { Module } from '@nestjs/common';
import { MongooseModule } from '@nestjs/mongoose';
import { GraphQLModule } from '@nestjs/graphql';
import { ApolloDriver, ApolloDriverConfig } from '@nestjs/apollo';
import { join } from 'path';

@Module({
  imports: [
    MongooseModule.forRoot('mongodb://localhost/nestjs-query'), // Update with your MongoDB connection string
    GraphQLModule.forRoot<ApolloDriverConfig>({
      driver: ApolloDriver,
      autoSchemaFile: join(process.cwd(), 'src/schema.gql'),
    }),
    // Import your feature modules here
  ],
})
export class AppModule {}

import { Module } from '@nestjs/common';
import { MongooseModule } from '@nestjs/mongoose';
import { GraphQLModule } from '@nestjs/graphql';
import { ApolloDriver, ApolloDriverConfig } from '@nestjs/apollo';
import { join } from 'path';

@Module({
  imports: [
    MongooseModule.forRoot('mongodb://localhost/nestjs-query'), // Update with your MongoDB connection string
    GraphQLModule.forRoot<ApolloDriverConfig>({
      driver: ApolloDriver,
      autoSchemaFile: join(process.cwd(), 'src/schema.gql'),
    }),
    // Import your feature modules here
  ],
})
export class AppModule {}

Step 3: Define Your Mongoose Schemas and Models Create your Mongoose schemas and models. For example, let's create a BlogPost schema:

import { Prop, Schema, SchemaFactory } from '@nestjs/mongoose';
import { Document } from 'mongoose';

@Schema()
export class BlogPost extends Document {
  @Prop()
  title: string;

  @Prop()
  content: string;

  @Prop()
  createdAt: Date;
}

export const BlogPostSchema = SchemaFactory.createForClass(BlogPost);

import { Prop, Schema, SchemaFactory } from '@nestjs/mongoose';
import { Document } from 'mongoose';

@Schema()
export class BlogPost extends Document {
  @Prop()
  title: string;

  @Prop()
  content: string;

  @Prop()
  createdAt: Date;
}

export const BlogPostSchema = SchemaFactory.createForClass(BlogPost);

Step 4: Create DTOs and Resolvers Define your DTOs (Data Transfer Objects) and resolvers using Nest.js Query. For example:

import { ObjectType, Field, ID } from '@nestjs/graphql';
import { FilterableField, PagingStrategies, QueryOptions, Resolver } from '@nestjs-query/query-graphql';
import { BlogPost } from './blog-post.schema';

@ObjectType('BlogPost')
@QueryOptions({ pagingStrategy: PagingStrategies.OFFSET })
export class BlogPostDTO {
  @FilterableField(() => ID)
  id: string;

  @FilterableField()
  title: string;

  @FilterableField()
  content: string;

  @FilterableField()
  createdAt: Date;
}

@Resolver(() => BlogPostDTO)
export class BlogPostResolver extends CRUDResolver(BlogPostDTO) {
  constructor(readonly service: BlogPostService) {
    super(service);
  }
}

import { ObjectType, Field, ID } from '@nestjs/graphql';
import { FilterableField, PagingStrategies, QueryOptions, Resolver } from '@nestjs-query/query-graphql';
import { BlogPost } from './blog-post.schema';

@ObjectType('BlogPost')
@QueryOptions({ pagingStrategy: PagingStrategies.OFFSET })
export class BlogPostDTO {
  @FilterableField(() => ID)
  id: string;

  @FilterableField()
  title: string;

  @FilterableField()
  content: string;

  @FilterableField()
  createdAt: Date;
}

@Resolver(() => BlogPostDTO)
export class BlogPostResolver extends CRUDResolver(BlogPostDTO) {
  constructor(readonly service: BlogPostService) {
    super(service);
  }
}

Step 5: Create a Service Create a service to handle the business logic for your BlogPost entity:

import { Injectable } from '@nestjs/common';
import { InjectModel } from '@nestjs/mongoose';
import { Model } from 'mongoose';
import { BlogPost } from './blog-post.schema';
import { BlogPostDTO } from './blog-post.dto';
import { CRUDService } from '@nestjs-query/query-mongoose';

@Injectable()
export class BlogPostService extends CRUDService<BlogPost> {
  constructor(@InjectModel(BlogPost.name) model: Model<BlogPost>) {
    super(model);
  }
}

import { Injectable } from '@nestjs/common';
import { InjectModel } from '@nestjs/mongoose';
import { Model } from 'mongoose';
import { BlogPost } from './blog-post.schema';
import { BlogPostDTO } from './blog-post.dto';
import { CRUDService } from '@nestjs-query/query-mongoose';

@Injectable()
export class BlogPostService extends CRUDService<BlogPost> {
  constructor(@InjectModel(BlogPost.name) model: Model<BlogPost>) {
    super(model);
  }
}

Step 6: Register the Module Finally, register your module in the app.module.ts file: ```typescript import { Module } from '@nestjs/common'; import { MongooseModule } from '@nestjs/mongoose'; import { BlogPost ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
