Use Lists to store large amounts of data. List is a quick way to and data. Also list is preferred way for organize .
List - it is a collection of properties or users.
Examples:
history (orders history, transactions, payments history, locations history, etc)
large price lists
table of cities with population
results for
referrals list
Do not use JSON property to collect a large array. This is a very bad practice.
"Execution timeout" error - it is typical error if you use JSON prop for large data.
Use a List.
List initialization
Before using the list (new or existing), you need to initialize it.
List can be global for Bot:
let list = new List({ name: "MyList" })
Bot.inspect(list.exist) // false for new List, true for already exist list
or can be personal for user:
let list = new List({ name: "MyList", user: user })
// or for user id
let list = new List({ name: "MyList", user_id: user.id })
After it you can perform another list methods
Create new list
// for list saving
if(!list.exist){
list.create()
}
Remove list
list.remove();
Recount list
Recalculate all statistical data in list.
Can spent 5-30 seconds and more for big list. So you need perform this task on background once in week/day or hour.
if (list.isRecountNeeded()) {
list.recount({
// this command will be runned after recount
// onComplete: 'onCompleteListRecount'
});
}
you can get delay time in ms:
// total delay in ms
list.recount_delay.total
// need to wait for next recount in ms
list.recount_delay.current_value
recount lag:
// you can change lag for next recount
// it is 1000 ms by default
// prefer to use 1000 - 2000
list.recount_delay.lag = 1000;
Calculate the amount of all props and users
list.count; // integer value
Properties management
Add bot property to bot list
Bot property can be added to List for bot
Example. Bot can have price list.
Bot.setProperty({
name: 'product1',
value: 'Nano Cloud',
type: 'string',
list: 'PaidPlans' // bot list will be created if not exist
});
Add user property to user list
User property can be added to List for user
Example. User can have Orders list
User.setProperty({
name: "order125",
value: { product_id: "product1", price: 28 },
type: "json",
list: "Orders", // bot list will be created if not exist
});
Add user property to bot list
User property can be added to List for bot
Example. Bot can have top customers list.
let list = new List({ name: "TopCustomers" })
if(!list.exist){ list.create() }
User.setProperty({
name: "customer" + user.id,
value: 20, // total income in USD
type: "float",
list: list,
// you can set this prop for other user also:
// user_id: other_user.id
});
Reject property
Reject property from list without destroying by prop name
list.rejectProperty("stringProp");
Remove property
Reject property from list and destroy it by prop name
list.removeProperty("stringProp");
Reject all properties (and all users)
Reject all properties from list
this method reject all properties and all users from list
list.rejectAll();
Remove all properties (and reject all users)
Remove all properties from list
this method remove all properties and reject all users from list
list.rejectAll();
Users management
Add user
list.addUser(user);
// or if you have id only
// list.addUser({ id: user.id });
Reject user
Reject user from list
list.rejectUser(user);
// or by id
list.rejectUser({ id: user.id });
Reject all users
Reject all users from list
list.rejectAllUsers();
Getting data
Getting props from list
let props = list.get();
Bot.inspect(props[0])
/* result will be like:
{
"name": "stringProp",
"value": "Bad Apple",
"user": {
"id": null
},
"created_at": "2020-11-09T01:46:52.270Z",
"updated_at": "2020-11-09T01:46:52.270Z"
}
*/
Getting users from list
let users = list.getUsers();
Bot.inspect(users[0])
Paginating
We have pages for data. Data is given page by page from the first page.
One page have 100 items by default.
// page 1
let props = list.get();
let users = list.getUsers();
// page 2
list.page = 2
props = list.get(); // getting props from page 2
users = list.getUsers(); // getting users from page 2
// it is possible to change default per page
list.per_page = 10 // 100 by default
// total pages
let total_pages = list.total_pages;
User searching
Getting user by id from list
// getting user from list if exist
list.getUser({ id: user.id })
Checking the user's existence in the list
list.haveUser(user)
// or by id:
list.haveUser({ id: user.id })
