connection.dropDb() not works

[Achi-Z]

jsstore is awesome, thank you for it :)

when use it, i got a little problem here :

using your example code 'JsStore_Demo', it success to create and connect,

but fail to drop db by your exmaple code :

connection.dropDb().then(function() {
console.log('Db deleted successfully');
}).catch(function(error) {
console.log(error);
});;

error info is ---

@Achi-Z could you provide a reproducable repo ? I have added test cases for dropDb and it has passed, so there is a chance something is different in your scenario.

`
var connection = new JsStore.Connection(new Worker('jsstore.worker.js'));

var dbName = 'JsStore_Demo';
var tblProduct = {
name: 'Product',
columns: {
// Here "Id" is name of column
id: {
primaryKey: true,
autoIncrement: true
},
itemName: {
notNull: true,
dataType: "string"
},
price: {
notNull: true,
dataType: "number"
},
quantity: {
notNull: true,
dataType: "number"
}
}
};
var database = {
name: dbName,
tables: [tblProduct]
}

async function initDb() {
const isDbCreated = await connection.initDb(database);
if (isDbCreated === true) {
console.log("db created");
} else {
console.log("db opened");
}
}

// initDb();

async function removeDbA() {
const isDbCreated = await connection.dropDb();
if (isDbCreated === true) {
console.log("db droped A");
} else {
console.log("db droped err A");
}
}
removeDbA();
async function removeDbB() {
const isDbCreated = await connection.dropDb(database);
if (isDbCreated === true) {
console.log("db droped B");
} else {
console.log("db droped err B");
}
}
removeDbB();
async function removeDbC() {
const isDbCreated = await connection.dropDb(tblProduct);
if (isDbCreated === true) {
console.log("db droped C");
} else {
console.log("db droped err C");
}
}
removeDbC();`

all action of droping are not work :(

that is because you are not initiating the database, you need to initiate db first -> then you can call dropDb.

If you want to delete three db, initiate each db and then delete. you can create multiple instance of jsstore for parallely deleting db.
