I have created four postresql tables. I am using nodejs with knexjs as a query builder.

I can create and execute migrations with the command line without any problems. Now I want to run migrations via Javascript. How can I proceed with this?

Here is my code: -

module.exports.runDBMigrations = async () => {
    knex.schema.hasTable(USERS_DB_NAME).then(function (exists) {
        if (!exists) {
            //Execute migrations to create users tables
        }
    })
        .catch(e => {
            console.log("Error creating tables: ", e);
        })

    knex.schema.hasTable(POSTS_DB_NAME).then(function (exists) {
        if (!exists) {
            //Execute migrations to create posts tables
        }
    })
        .catch(e => {
            console.log("Error creating tables: ", e);
        })

    knex.schema.hasTable(LIKES_DB_NAME).then(function (exists) {
        if (!exists) {
            //Execute migrations to likes users tables
        }
    })
        .catch(e => {
            console.log("Error creating tables: ", e);
        })

    knex.schema.hasTable(FOLLOWERS_DB_NAME).then(function (exists) {
        if (!exists) {
            //Execute migrations to create followers tables
        }   
    })
        .catch(e => {
            console.log("Error creating tables: ", e);
        })

}
