I am running into the error: Error: Query.totalPosts defined in resolvers, but not in schema. I have been looking for a solution but am unable to find a work around or a solution.
my server.js:
const express = require('express')
const {ApolloServer} = require('apollo-server-express');
const http = require('http');
const path = require('path');
const {fileLoader, mergeTypes} = require('merge-graphql-schemas');
require('dotenv').config();
// //resolvers`enter code here
const resolvers = {
Query: {
totalPosts: () => 42,
me: () => 'Gaia'
}
};
const typeDefs = mergeTypes(fileLoader(path.join(__dirname, './typeDefs')));
async function startApolloServer(typeDefs, resolvers){
const apolloServer = new ApolloServer({typeDefs, resolvers});
const app = express();
// typeDefs
// const typeDefs = mergeTypes(fileLoader(path.join(__dirname, './typeDefs')));
await apolloServer.start();
//this method connects Apollo server to a specific HTTP framework ie: express
apolloServer.applyMiddleware({app, path: '/graphql'});
apolloServer.applyMiddleware({ app });
const httpserver = http.createServer(app);
// rest endpoint
app.get('/rest', function(req, res) {
res.json({
data: 'hit rest endpoint'
});
});
app.listen(process.env.PORT, function() {
console.log(`Server running at http://localhost:${process.env.PORT}`);
console.log(`Graphql server running at http://localhost:${process.env.PORT}${apolloServer.graphqlPath}`);
});
};
startApolloServer(typeDefs, resolvers);
Your field totalPosts exist in typeDef ? As documentation said in step 3, https://www.apollographql.com/docs/apollo-server/getting-started/ , you have to define your graphql schema for use it.
Every GraphQL server (including Apollo Server) uses a schema to define the structure of data that clients can query. In this example, we'll create a server for querying a collection of books by title and author.
You should type something like this :
type Query {
totalPost: Int
me: String
}
And, when i build a graphql api on nest.js, schema file automaticly build. I guess, it's same way with express. Did you try to setup your api following this doc : https://www.apollographql.com/docs/apollo-server/v2/integrations/middleware
typeDef look like automaticly resolve and push to a schema file. You may re-load your serve when it's should be update.
const express = require('express');
const { ApolloServer } = require('apollo-server-express');
const { typeDefs, resolvers } = require('./schema');
async function startApolloServer() {
const app = express();
const server = new ApolloServer({
typeDefs,
resolvers,
});
await server.start();
server.applyMiddleware({ app });
app.use((req, res) => {
res.status(200);
res.send('Hello!');
res.end();
});
await new Promise(resolve => app.listen({ port: 4000 }, resolve));
console.log(`🚀 Server ready at http://localhost:4000${server.graphqlPath}`);
return { server, app };
}
