Problem to run migration

[lmoraobando]

Hi Stefano,

I'd like to implement this backend but I get this error "Error: Cannot register a type name as a singleton without a "to" token"

when I tried to run:
yarn dev:server

do you have any solution?

Hi @lmoraobando,

It is probable a problem with your .env file.

Did you follow this step?

"Also, you have to configure the environment variables in the .env file, based on a .env.example file that is provided in the backend folder, change the variables according to your environment."

Best,

U need "ormconfig.json" on your backend folder, take this sample just change user,password and database:

[
{
"name": "default",
"type": "postgres",
"host": "localhost",
"post": 5432,
"username": "postgres",
"password": "mdp",
"database": "barberbase",
"entities": [
"./src/modules//infra/typeorm/entities/.ts"
],
"migrations": [
"./src/shared/infra/typeorm/migrations/.ts"
],
"cli": {
"migrationsDir": "./src/shared/infra/typeorm/migrations"
}
},
{
"name": "mongo",
"type": "mongodb",
"host": "localhost",
"port": 27017,
"database": "myLegendaryDatabase",
"useUnifiedTopology": true,
"entities": [
"./src/modules//infra/typeorm/schemas/*.ts"
]
}
]
