How to hardcode / prepopulate LokiJS Database - lokijs

Question

I'm just starting off with LokiJS and I have one fundamental question I can't wrap my head around:
Is there a way to hardcode a LokiJS database? Or do I have do add all the data via Javascript?
It seems necessary to me, to have something like PHPMyAdmin to inspect/add/delete the actual data in the database, but I have found nothing so far, to do this with a LokiJS database. Isn't this a big loss in usability?

Answer 1

Lokijs.org
A fast, in-memory document-oriented datastore for node.js, browser and cordova.
Use cases:
To achieve database like feature on a limited resources (Raspberry Pi like) device.
To create secure applications without running an server.
To persist data and reuse it, for rich feature applications at client side.
..
The list can go on up 100 points.
Big loss in usability?
No.
Because it fulfills the purpose for which it is introduced. (In memory datastore)
Is there a way to hard-code a LokiJS database?
Yes.
Create a yourExampleDB.json or yourExampleDB.db file and insert data in a following manner.
{
"filename": "yourExampleDB.db",
"collections": [{
"name": "entries",
"data": [{
"id": 17948697,

"meta": {
"revision": 0,

},
"$loki": 2
},
...
...

It's a valid example copy of lokijs db.
something like PHPMyAdmin to inspect/add/delete?
No.
Or do I have do add all the data via JavaScript?
Yes
Steps to follow
Require lokijs module.
Create a db.
Create a collection.
Insert your data.
Persist it (Manual/Auto)
Hope it helps.
