01-cats-app - npm run start:prod

Hello

@kamilmysliwiec

I have created a repo I have built typeorm - jest - class-validator - passport all is fine but when I run the command “npm run start: prod” the following error message appears, I thought that this is a bad configuration but I tested the command in the application “01-cats-app” but the error always appears

E:\Projets\WebStorm\01-cats-app\01-cats-app>npm run start:prod

> nest-typescript-starter@1.0.0 prestart:prod E:\Projets\WebStorm\01-cats-app\01-cats-app

I found the problem.

It’s related to TypeORM’s ormconfig.json. By default it looks for entities in the /src folder and opens TypeScript files instead of the Javascript compiled ones.

The solution I found was using a dynamic ormconfig.js (instead of .json) that has a conditional path. Docs here => http://typeorm.io/#/using-ormconfig/loading-from-ormconfigjs

In my case my ormconfig.js looks like that (assuming that you have a dotenv variable called NODE_ENV) :

const SOURCE_PATH = process.env.NODE_ENV === 'production' ? 'dist' : 'src'

module.exports = {
    type: 'sqlite',
    database: './db/myDatabase.db',
    entities: [`${SOURCE_PATH}/**/**.entity{.ts,.js}`],
}

For everyone that gets this error in the examples, look in the ormconfig.json file, it looks for entities in the src directory.

When you run npm run start:prod the entities will be in the dist directory.
