[nodemon] app crashed - waiting for file changes before starting...

Environnement :

• Node : version v21.7.2

**J'ai essayer de faire les modifications suivantes : **
1 - fichier server/databese/connection.js suivante (remplacement de localhost par l'adresse 127.0.0.1):

const databaseUrl =
process.env.DATABASE_URL || "mongodb://127.0.0.1/argentBankDB";

2- fichier /.env (remplacement de localhost par l'adresse 127.0.0.1)

Une solution ??

Merci d'avance

So the documentation has a slight issue when making POST or PUT requests

When making a POST or PUT request, we must input a string with the keyword “Bearer” and then the JSON Web Token, like this:

"Bearer [JWT]"

Though there's a problem, for some unknown reason, when making the POST/PUT request,

Curl adds another double-quote at the end of the Authorization string value, making the token invalid:

So the developer has to remove the last double quote at the end of the JWT, so we end having to input the token like this:

"Bearer [JWT]

for the POST request to work properly

How to reproduce this error yourself

1. Start the Back-End server and go to the Swagger API doc. with this address: http://localhost:3001/api-docs/#/

2. Go to the User Module → POST - /user/login/ → add the “[email protected]” to the email and “password123” for the password:
   

3. Click “execute” and copy the JWT without the double quotes:
   

4. Go to POST - /user/profile/ → Input your JWT like this:

"Bearer [JWT]"

Example:

(NB: I changed the width of the input in CSS to make the entire JWT visible)

5. Click the “Execute” button, and you'll see an error message that the token is invalid:
   

Do you struggle to install the API on macOS ?

If you have the error [nodemon] app crash... you probably didn't install MongoDB Community Edition.
And don't worry if the mongo --version is not working....

What I did to fix the error:

1. Follow this link for complete instructions https://www.mongodb.com/docs/manual/tutorial/install-mongodb-on-os-x/
2. If you don't have home brew package manager installed (global) then: https://brew.sh/index_fr

So once brew is installed, in your macOS terminal: you can run:

1. brew tap mongodb/brew

2. brew install [email protected]

⚠️ like me, you can have this error:

If you had it just follow the img instructions (so install xcode-select) and then launch again brew install [email protected]

3. now you can check the install with mongod --version

4. and then run mongodb community with brew services start [email protected]

(to stop it : brew services stop [email protected])

Now, you can clone the repo and:

1. npm i
2. add MongoDB NodeJS Driver npm install mongodb --save
3. Start your local server npm run dev:server
4. Get the populate database npm run populate-db

✨ Your Api should be ready 😃

👉 http://localhost:3001/api-docs/

Hope it helps ! 👋

Est-ce normal que lorsqu'on exécute la commande npm run populate-db la réponse renvoyé est :

ISSUS 1 :

désinstaller mongo et réinstaller une version antérieur a la version 6 (5.0.23)

ISSUS 2:

• modifier dans le fichier .env "localhost" par "127.0.0.1"
• modifier également dans "server/database/connection.js" par :

const databaseUrl =
  process.env.DATABASE_URL || 'mongodb://127.0.0.1/argentBankDB'

A user should be able to:

• Navigate to the home page (/)
• See all placeholder data from mockup

Here is a simple way how to install the project using docker :

Step 1
in the connection.js file, add the property : useUnifiedTopology: true to the url connection :

await mongoose.connect(databaseUrl, { useNewUrlParser: true, useUnifiedTopology: true })

Step 2
At the root level of the project, create a DockerFile :

# Use the official Node.js 12 image as base image
FROM node:12
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 3001
CMD ["npm", "run", "server"]

Step 3
At the root level of the project, create a docker-compose.yml

version: '3'

services:
  # Node.js application service
  app:
    build:
      context: .
    ports:
      - "3001:3001"
    depends_on:
      - mongo
    environment:
      DATABASE_URL: "mongodb://mongo/argentBankDB"  # Use the service name 'mongo' as the hostname

  # MongoDB service
  mongo:
    image: mongo
    user: '502:502'
    ports:
      - "27017:27017"
    volumes:
      - ./data:/data/db:rw

volumes:
  mongo:
    external: true

The line user: '502:502 is needed to give you the right to copy the data folder from your container in your local machine.
You probably need to change the ID by your own id (on mac os you can get it by running : id -u in a terminal)
`Step 4

run docker-compose up

Step 5
At this step your project is running (api + mongodb).
Now you need to populate the database. Here is how you can do :

• Get your container ID by running docker container ls
• Run the following command : docker exec -it 00460714d1d9 bash
• Then you can just run the command npm run populate-db

Unable to connect to the mongodb database.

After typing the following command npm run dev:develop :

Dans les explications de la mise en place du projet,
il n'est pas indiqué quelle version de Node et Mongo, il faut installer, car certaines mises à jour peuvent bloquer la mise en place du server.

De plus, vous indiquez qu'il est possible de vérifier que le server marche si on va sur le lien suivant :
http://locahost:3001/ mais il ne marche pas parce qu'il manque le "l" donc si personne ne fait attention ou qu'il ne le tape pas d'eux même, ils peuvent se retrouver dans un problème qu'y n'est pas.
