Expected Behavior

Database should open and initialize tables successfully in production and debug modes.

Current Behavior

Database is opening in debug mode and failing in production

Steps to Reproduce (for bugs)

Using typeorm I have created entities in the following form:

import { EntitySchema } from 'typeorm';
import { StorageModel } from '../models/StorageModel';

export default new EntitySchema({
  name: 'Storage',
  target: StorageModel,
  columns: {
    key: { type: 'text', primary: true },
    value: { type: 'text' },
  },
});

Then I am opening database with the following config:

createConnection({
      name: 'db.sqlite',
      type: 'react-native',
      database: 'react-native',
      location: 'default',
      // logging: ['error', 'query', 'schema'],
      synchronize: true,
      entities: [
        Translation,
        User,
        Post,
        Download,
        Asset,
        Option,
        QueuedRequest,
        Storage,
        HelpItem,
      ],
    });

In debug the database opens correctly and I have used it to create many features. It was going very well until I tried building the release apk. I get the following error in adb logcat…

This issue is due to minification in release mode changing class names and file names. It can be fixed with the following steps:

1. yarn add metro-minify-terser
2. Update the metro config to keep class names and file names. Add the following to the metro.config.js transformer:

minifierPath: 'metro-minify-terser',
minifierConfig: {
    ecma: 8,
    keep_classnames: true,
    keep_fnames: true,
    module: true,
    mangle: {
        module: true,
        keep_classnames: true,
        keep_fnames: true,
    },
 },

Is there a way to instruct typeorm to treat migrations properly without the use of class names, like maybe giving it an array of tuples (migration class, timestamp)?
