No changes in database schema were found - cannot generate a migration. To create a new empty migration use "typeorm migration:create" command.

How do I load the data source , and typeOrmModule.forRoot from same .env file ? anyone has any idea or can give me some hints please ? Thanks

"No changes in database schema were found - cannot generate a migration" issue. Did anyone solve this ? I'm using typeorm 0.3. Thanks

This reply from Yaseen shaik might work 1. Stop all the executions. 2. delete the generated sql file. 3. do "npm run start:dev" or "yarn start:dev" 4. Open another terminal in the root directory 5. and enter the migration:generate command as shown in the video. Hope this solve your issue.

Can you inject the config service to datasource for env vars? I can only get it working with dotenv package, it'd be nice if there was a workaround by using config service itself

Still couldn't make it happen

Hey, i am having issues when doing this in a express-ts project without nextjs. I have a src folder which contains ts files and a dist folder which output js files in same name as ts except with .js extension. Everything is working except the migrations commands. "start": "cross-env NODE_ENV=dev node dist/server.js", "typeorm": "npm run start && ts-node ./node_modules/typeorm/cli", "typeorm:generate-migration:win": "npm run typeorm -- -d ./src/api/database/initialize.ts migration:generate ./dist/api/database/migrations/FirstMigration" The commands run but the migration file doesnot generate. Please help

[@amitavroydev]

Hmm, I haven't looked at the integration of TypeORM with Express yet. However, tell me one thing - does it work properly if sync is set to true?

Everyone who gets this warning:'No changes in database schema were found - cannot generate a migration. To create a new empty migration use "typeorm migration:create" command' - This is either because you did not have Entity() decorator or because the table already exists in the DB. Remember, in the video, the table was first deleted before the command to run migrations was run
