TypeORM Entity in NESTJS - Cannot use import statement outside a module

Question

Started new project with \'nest new\' command. Works fine until I add entity file to it.

Got following error:

import { Entity, Column, Primary

Answer 1

In the TypeORM documentation, i found a specific section for Typescript.

This section says:

Install ts-node globally:

npm install -g ts-node

Add typeorm command under scripts section in package.json

"scripts" {
    ...
    "typeorm": "ts-node -r tsconfig-paths/register ./node_modules/typeorm/cli.js"    
}

Then you may run the command like this:

npm run typeorm migration:run

If you need to pass parameter with dash to npm script, you will need to add them after --. For example, if you need to generate, the command is like this:

npm run typeorm migration:generate -- -n migrationNameHere

This works with my file config:

{
    "type": "postgres",
    "host": "yourhost",
    "port": 5423,
    "username": "username",
    "password": "password",
    "database": "your_db",
    "synchronize": true,
    "entities": [
        "src/modules/**/*.entity.{ts,js}"
    ],
    "migrations": [
        "src/migrations/**/*.{ts,js}"
    ],
    "cli": {
        "entitiesDir": "src/modules",
        "migrationsDir": "src/migrations"
    }
}

Then you can run the generate command.
