add backup.ts, restore.ts files to dump and restore mongodb

[machi1990]

Feature Request

Current, OVP https://github.com/aerogear/OpenVolunteerPlatform/blob/master/platform/server/src/db.ts is doing multiple functionalities of backing up the db and restoring it by default.

Is your feature request related to a problem? Please describe.

• Doing backup is tedious and involves loads of manual work
• Not that much of a problem but doing data restoring each time when there is no need slow the boot time, where at this phase we just need to establish a connection to mongodb.

Describe the solution you'd like

Maybe we can split this into two parts:

• a backup.ts file which will do the dumping process
• a restore.ts file which will do the restoring process
• a connect.ts file which just creates a db connection (this can be the the db.ts file)

The first two files can lead to scripts in package.json

{
  "scripts": {
     .....
    "backup": "ts-node server/backup.ts",
    "restore": "ts-node server/restore.ts"
     }
}

Describe alternatives you've considered
Right now If we want to do backup, we just have to uncomment the backup part in db.ts, without forgetting to comment it back to avoid backing up the data each time.

@machi1990 that will be perfect issue for DataSync starter

[machi1990]

Makes sense, let me transfer the issue there?

[wtrocki]

Actually this is only valid for this app as we have initial data.

Changed my mind. Data dump restore feature could be improved

[machi1990]

Yes, we have it only for the OVP app but seems to me like a typical use case so having dumping and restore features at least as commands could do it.
