No metadata for "User" was found using TypeOrm

Question

I'm trying to get a basic setup working using TypeORM, and getting this error following the setup.

Here is a REPL (just do yarn install && yarn db:dev followed by yarn db:migrate && yarn start to reproduce the error)

Inserting a new user into the database...
{ EntityMetadataNotFound: No metadata for "User" was found.

Answer 1

Adding answer bit late but its very common error.

There are two main reasons for above error. In OrmConfig,

1. You have used *.ts instead of *.js. For example,

entities: [__dirname + '/../**/*.entity.ts']  <-- Wrong

It should be

entities: [__dirname + '/../**/*.entity.js'] 

2. entities path is wrong. Make sure, entities path is defined according to dist folder not src folder.

Answer 2

The problem is on ormConfig

Please try to use this:

entities: [__dirname + '/../**/*.entity.{js,ts}']
