when i use toLogin in methods it works, but use in setup and return(in this code - test) i get error Cannot read property 'username' of undefined doesnt work, why?
export default {
name: "Login",
setup() {
const username = ref("");
const password = ref("");
const router = useRouter();
const test = async () => {
console.log(this.username.value)
}
return {
username,
password,
router,
test
};
},
methods: {
async toLogin() {
const rep = await axios.post("login", {
username: this.username,
password: this.password,
});
console.log(rep)
//await this.router.push("/successlogin");
},
},
};
You don't need this. Instead, just use console.log(username.value). username is already captured in scope for the test function to use.
The docs here https://v3.vuejs.org/guide/composition-api-introduction.html#setup-component-option contain this example:
setup (props) {
const repositories = ref([])
const getUserRepositories = async () => {
repositories.value = await fetchUserRepositories(props.user)
}
return {
repositories,
getUserRepositories
}
}

Can you explain what I'm doing wrong, I don't understand why my header is empty. Login is working but when I trigger the me query it's not working, not authenticated appear and if I console log this it's undefined.
How to keep the user logged, and be able to acces the data ?
Here is my code, if you know what's wrong.
Thanks

Token is null right after login, It stores only if I refresh the page. It should store just after login without need to reload.
src/stores/index.ts:
const initialUser = JSON.parse(sessionStorage.getItem('Project:token') || '{}');
const useProject = defineStore('project-store', {
state: () => ({
token: initialUser as string | null,
status: initialUser ? { loggedIn: false } : { loggedIn: true },
}),
actions: {
async login(user: User) {
const token = await grantAuth(user);
this.loginSuccess = token;
},
loginSuccess(token: string) {
this.token = token;
this.status.loggedIn = !!token;
},
src/services/entryPoint.js:
import store from '../stores/index';
export default async function entryPoint() {
const getStore = async () => {
if (!store) {
store = await import('../stores/index');
} else {
if (store) {
const { token } = store;
if (token) {
return token;
}
}
}
};
}
src/services/api.js:
import axios from 'axios';
import entryPoint from './entryPoint';
const api = axios.create({ baseURL: import.meta.env.VITE_APP_API_URL });
const entry = entryPoint();
if (entry) {
api.defaults.headers.Authorization = `Bearer ${entry}`;
}
export default api;
src/services/auth.js:
import api from './api';
const requestToken = encodedData => {
return api.post('/projects/login', null, {
headers: {
Authorization: `Basic ${encodedData}`,
},
});
}
const registerToken = data => {
if (data && data.token) {
sessionStorage.setItem('Project:token', JSON.stringify(data.token));
}
};
export const grantAuth = async user => {
const flatData = `${user.username.toUpperCase()}:${user.password}`;
const encodedData = btoa(flatData);
const response = await requestToken(encodedData);
registerToken(response.data);
return response.data ? response.data.token : null;
};
A solution would be to give the command window.location.reload(), however It is not viable for a SPA, It is preferable that the token to be available right after login
I'm learning to use the Redis for my backend database and I would like to try using redis-om for fastify not sure whether they are compatible or not, but I got error.
I use service of app.redislabs.com
I don't know what I just messed up? And how can I fix the problem?
server.js
const { createCar, createIndex } = require("./redis");
app.post("/add", async (req, res) => {
await createIndex();
const { make, model, image, description } = req.body;
const data = { make, model, image, description };
await createCar(data);
res.code(200).send('ok');
});
const PORT = 5000;
app.listen(PORT, function (err) {
if (err) {
app.log.error(err);
process.exit(1);
}
});
redis.js
const { Client, Entity, Schema, Repository } = require("redis-om");
const client = new Client();
const connect = async () => {
if (!client.isOpen()) {
await client.open("redis://default:password#localhost:6379");
} else {
console.log("CONNECTED");
}
};
class Car extends Entity {}
let schema = new Schema(
Car,
{
make: { type: "string" },
model: { type: "string" },
image: { type: "string" },
description: { type: "string" },
},
{ dataStructure: "JSON" }
);
const createCar = async (data) => {
await connect();
const repository = new Repository(schema, client);
const car = repository.createEntity(data);
const id = await repository.save(car);
return id;
};
const createIndex = async () => {
await connect();
const repository = new Repository(schema, client);
await repository.createIndex();
};
module.exports = {
createCar,
createIndex,
};
My JSON Body
You cannot call new on Repository. This is a breaking change I introduced in version 0.2.0 of Redis OM. There are a couple of others that are documented in the CHANGELOG.
Call const repository = client.fetchRepository(schema) instead, as shown here. Unfortunately, there are some videos and blogs that have the older syntax and so this crops up from time to time.
Thanks for using my library!
I'm building a GraphQL API and I want to test some resolvers and the database with jest.
Here is my helper file, where I set up the context and the Prisma Client for testing.
import { PrismaClient } from "#prisma/client";
import { ServerInfo } from "apollo-server";
import { execSync } from "child_process";
import getPort, { makeRange } from "get-port";
import { GraphQLClient } from "graphql-request";
import { nanoid } from "nanoid";
import { join } from "path";
import { Client } from "pg";
import { server } from "../api/server";
type TestContext = {
client: GraphQLClient;
db: PrismaClient;
};
export function createTestContext(): TestContext {
let ctx = {} as TestContext;
const graphqlCtx = graphqlTestContext();
const prismaCtx = prismaTestContext();
beforeEach(async () => {
const client = await graphqlCtx.before();
const db = await prismaCtx.before();
Object.assign(ctx, {
client,
db,
});
});
afterEach(async () => {
await graphqlCtx.after();
await prismaCtx.after();
});
return ctx;
}
function graphqlTestContext() {
let serverInstance: ServerInfo | null = null;
return {
async before() {
const port = await getPort({ port: makeRange(4000, 6000) });
serverInstance = await server.listen({ port });
return new GraphQLClient(`http://localhost:${port}`);
},
async after() {
serverInstance?.server.close();
},
};
}
function prismaTestContext() {
const prismaBinary = join(__dirname, "..", "node_modules", ".bin", "prisma");
let schema = "";
let databaseUrl = "";
let prismaClient: null | PrismaClient = null;
return {
async before() {
schema = `test_${nanoid()}`;
databaseUrl = `postgresql://user:123#localhost:5432/testing?schema=${schema}`;
process.env.DATABASE_URL = databaseUrl;
execSync(`${prismaBinary} migrate up --create-db --experimental`, {
env: {
...process.env,
DATABASE_URL: databaseUrl,
},
});
prismaClient = new PrismaClient();
return prismaClient;
},
async after() {
const client = new Client({
connectionString: databaseUrl,
});
await client.connect();
await client.query(`DROP SCHEMA IF EXISTS "${schema}" CASCADE`);
await client.end();
await prismaClient?.$disconnect();
},
};
}
My test file looks like this:
import { createTestContext } from "./__helpers";
const ctx = createTestContext();
it("register user", async () => {
const testUser = {
username: "Test",
email: "test#test.com",

const registerResult = await ctx.client.request(
`

register(username: $username, email: $email, password: $password) {
user {
user_id
username
email
}
}
}
`,
{
username: testUser.username,
email: testUser.email,
password: testUser.password,
}
);
const resultUsername = registerResult.register.user.username;
const resultEmail = registerResult.register.user.email;
const resultUserID = registerResult.register.user.user_id;
expect(resultUsername).toBe(testUser.username);
expect(resultEmail).toBe(testUser.email);
expect(resultUserID).not.toBeNull;
const users = await ctx.db.user.findMany();
const savedUser = users[0];
expect(savedUser.username).toBe(testUser.username);
expect(savedUser.email).toBe(testUser.email);
expect(savedUser.user_id).toBe(resultUserID);
expect(savedUser.first_name).toBeNull;
expect(savedUser.last_name).toBeNull;
expect(savedUser.role).toBe("USER");
expect(savedUser.password).not.toBe(testUser.password);
});
it("all events", async () => {
const eventsResult = await ctx.client.request(
`
query {
allEvents {
event_id
title
description
}
}
`
);
expect(eventsResult.allEvents.length).toBe(0)
});
When I just run one file with one test in it, everything works. But when I run multiple tests in one file, the first one runs normal, but the ones after not. I receive this error:
The table `test_LjrcmbMjI4vLaDYM9-lvw.Event` does not exist in the current database.: {"response":{"errors":[{"message":"\nInvalid `prisma.event.findMany()` invocation:\n\n\n The table `test_LjrcmbMjI4vLaDYM9-lvw.Event` does not exist in the current database.","locations":[{"line":3,"column":7}],"path":["allEvents"],"extensions":{"code":"INTERNAL_SERVER_ERROR","exception":{"code":"P2021","clientVersion":"2.11.0","meta":{"table":"test_LjrcmbMjI4vLaDYM9-lvw.Event"}}}}],"data":null,"status":200},"request":{"query":"\n query {\n allEvents {\n event_id\n title\n description\n }\n }\n "}}
Also when I run two tests in separated files, on every second test run I get this error:
listen EADDRINUSE: address already in use :::4200
I did the nexus tutorial (Step 4, and 5), where they explained how to test, but somehow it doesn't work. So please help me.

I have created a repo with parallel tests for the same here. The test environment setup is in the prisma folder and a similar helper is created in the tests folder.
I am building a simple app that uses JWT for authentication. But I keeps on getting the error saying the route I GET to require a call back function.
What do I expect?
I should be getting the current user's data back.
What do I actually get?
Error: Route.get() requires a callback function but got a [object Object]
Route:
const authenticate = require("../middlewares/authenticate");
const usersController = require("../controllers").users;
app.get("/users/me", authenticate, usersController.getMe);
Model:
"use strict";
const jwt = require("jsonwebtoken");
module.exports = (sequelize, DataTypes) => {
var User = sequelize.define(
"User",
{
email: DataTypes.STRING,
password: DataTypes.STRING
},
{
classMethods: {
associate: function(models) {
// associations can be defined here
},
findByToken: function(token) {
const User = this;
let decoded;
try {
decoded = jwt.verify(token, "leogoesger");
} catch (e) {
console.log(e);
}
return User.find({ where: { email: decoded.email } });
}
}
}
);
return User;
};
Middleware:
const { User } = require("../models/user");
const authenticate = (req, res, next) => {
console.log("called here");
const token = req.header("x-auth");
User.findByToken(token)
.then(user => {
if (!user) {
}
req.user = user;
req.token = token;
next();
})
.catch(e => {
res.status(401).send(e);
});
};
module.exports = { authenticate };
Controller:
module.exports = {
getMe(req, res) {
res.status(200).send({ message: "hello" });
}
};
Your authenticate module exports an object, yet you do this:
const authenticate = require("../middlewares/authenticate");
which means your const authenticate is an object, not your function. Change that to this:
const authenticate = require("../middlewares/authenticate").authenticate;
Or, change the module to export the function directly instead of exporting an object with the function in it.
