How to delete a Collection in LokiJS












0















I been working on LokiJS on Node recently, And I could'nt find a command that deletes the entire Collection itself,



I tried with these commands with an assumption it would exist, I could not find any docs/ samples to delete a collection.



// let result = this.db.dropCollection(collectionName);
// let result = this.db.removeCollection(collectionName);
// let result = this.db.deleteCollection(collectionName);



Other way around I know I can achieve the same by reading the file and removing the entire object, But is there a built-in LokiJS function?

          To delete a collection you need to use the removeCollection() method on the main Loki object. See docs here.



          For example, if you have your Loki instance initialized like this:



          const loki = require('lokijs');
          const lokidb = new loki();

          // Add a collection (that we will remove later)
          let myCollection = lokidb.addCollection('myCollection');


          Now lokidb is your main loki object, and this is the object that you need to execute the removeCollection() from.



          // Let's remove the collection
          lokidb.removeCollection('myCollection');

          // * poof * ....
          // myCollection is now gone


          I don't know exactly how you have your loki db set up, but hopefully this example helps.
