Optimize order creation performance #675
Conversation
- Add image caching system to eliminate file I/O operations during order creation - Implement database indexes for frequently queried collections (users, orders, communities) - Consolidate community lookup queries to reduce database calls - Add graceful handling of existing database indexes - Replace deprecated Order.count() with Order.countDocuments() These optimizations significantly reduce order creation response times from 6-9 seconds to under 1 second.
WalkthroughThe changes introduce centralized helper functions for community lookup and currency validation, refactor order command logic to use these helpers, and add a new module for managing MongoDB indexes. Additionally, the order creation logic is updated to accept an optional community ID, and new indexes are created during application startup for improved database performance. Changes

2-2: Remove unused import.The
Communityimport is no longer used after refactoring to usegetCommunityInfo.-import { Community, Order } from '../../../models'; +import { Order } from '../../../models';
🧹 Nitpick comments (9)
models/indexes.ts (6)
7-27: Consider using proper MongoDB types instead ofany.Using
anytype for the collection parameter reduces type safety. Consider importing and using the proper MongoDB Collection type from mongoose.+import { Collection } from 'mongoose'; + -const checkIndexExists = async (collection: any, indexSpec: any): Promise<boolean> => { +const checkIndexExists = async (collection: Collection, indexSpec: Record<string, number>): Promise<boolean> => {
51-58: Use optional chaining for safer error handling.The static analysis correctly identifies that optional chaining would be safer here.
- if (error.message && error.message.includes('already exists')) { + if (error?.message?.includes('already exists')) {
7-7: Improve type safety for better maintainability.Consider using more specific types instead of
anyfor better type safety and IDE support.-const checkIndexExists = async (collection: any, indexSpec: any): Promise<boolean> => { +const checkIndexExists = async ( + collection: mongoose.Collection, + indexSpec: Record<string, number> +): Promise<boolean> => {
12-20: Consider potential edge cases in index comparison logic.The JSON.stringify approach for comparing index specifications might not handle all edge cases, such as different key ordering or complex index options. While it works for the current use cases, consider using a more robust comparison method.
Alternative approach using lodash isEqual or custom comparison:
- // Convert our index spec to a comparable format - const targetKeys = JSON.stringify(indexSpec); - - // Check if any existing index matches our specification - for (const existingIndex of existingIndexes) { - const existingKeys = JSON.stringify(existingIndex.key); - if (existingKeys === targetKeys) { - return true; - } - } + // Check if any existing index matches our specification + for (const existingIndex of existingIndexes) { + if (deepEqual(existingIndex.key, indexSpec)) { + return true; + } + }
32-37: Improve type safety for function parameters.Similar to the previous function, consider using more specific types for better type safety.
-const createIndexSafely = async ( - collection: any, - indexSpec: any, - options: any, - collectionName: string -): Promise<void> => { +const createIndexSafely = async ( + collection: mongoose.Collection, + indexSpec: Record<string, number>, + options: mongoose.IndexOptions & { name: string }, + collectionName: string +): Promise<void> => {
53-53: Use optional chaining for cleaner code.The static analysis tool correctly identifies that optional chaining would be cleaner and safer here.
- if (error.message && error.message.includes('already exists')) { + if (error.message?.includes('already exists')) {bot/ordersActions.ts (1)
74-74: Consider handling undefined community_id in getFee function instead of using empty string fallback.Instead of passing
community_id || ''at every call site, it would be cleaner to handle undefined community_id within the getFee function itself.Consider updating the getFee function to accept an optional community_id parameter and handle the undefined case internally, then update the calls:
- const fee = await getFee(amount, community_id || ''); + const fee = await getFee(amount, community_id);and
- await getFee(amount, community_id || '', true) : + await getFee(amount, community_id, true) :Also applies to: 108-108
util/communityHelper.ts (2)
24-24: Remove unnecessary initialization of communityId.The static analysis correctly identifies that initializing
communityIdtoundefinedis redundant.- let communityId: string | undefined = undefined; + let communityId: string | undefined;
50-50: Consider using strict equality for ID comparison.Using loose equality (
==) for ID comparison could lead to unexpected behavior. If this is intentional for comparing MongoDB ObjectIds with strings, consider adding a comment explaining the rationale.- isBanned = community.banned_users.some((buser: any) => buser.id == user._id); + isBanned = community.banned_users.some((buser: any) => String(buser.id) === String(user._id));

Learning: In the IOrder interface from bot/commands.ts, the secret property is typed such that it cannot be undefined, only null or string. Therefore, checking only for null is sufficient and checking for undefined is unnecessary.

Learning: In the IOrder interface from models/order.ts, the secret property is typed as `string | null`, which means it can never be undefined in TypeScript strict mode. Therefore, checking only for null is sufficient and checking for undefined is unnecessary.

Learning: In the IOrder interface, the hash property is typed as `string | null` (not including undefined), so checking specifically for null with `if (order.hash === null)` is the correct and most precise approach rather than using a falsy check like `if (!order.hash)`.

🔇 Additional comments (9)
models/indexes.ts (5)
65-140: Well-structured index creation with appropriate error handling.The index creation logic is well-implemented:
- Indexes are created in the background to avoid blocking
- Appropriate compound indexes for query optimization
- Case-insensitive collation for community group lookups
- Graceful error handling prevents app startup failure
73-81: LGTM! Well-designed compound index for order queries.The compound index on
creator_idandstatusis well-designed for the query patterns mentioned in the PR objectives, particularly for efficiently finding pending orders by creator.
98-107: Excellent use of case-insensitive collation for community lookups.The collation setting with strength 2 provides case-insensitive matching for community group names, which is appropriate for user-friendly community lookups.
124-133: Good use of unique constraint on telegram ID.The unique index on
tg_idprevents duplicate users and optimizes user lookups, which aligns with the application's user management requirements.
136-140: Robust error handling prevents startup failures.The comprehensive error handling that logs errors without throwing exceptions is well-designed to prevent application startup failures while still providing visibility into index creation issues.
app.ts (1)
10-10: Appropriate integration of index creation during startup.The index creation is correctly placed after MongoDB connection establishment and before other initialization steps, ensuring optimal query performance from the start.
Also applies to: 31-33
util/communityHelper.ts (1)
17-66: Excellent consolidation of community lookup logic.The
getCommunityInfofunction effectively consolidates multiple database queries into a single, reusable utility. The logic handles both group and private chat contexts appropriately, and the automatic cleanup of invalid default community IDs is a nice touch.bot/modules/orders/commands.ts (2)
194-196: Correct migration from deprecated Order.count to Order.countDocuments.Good job updating to use
countDocumentsinstead of the deprecatedcountmethod, and fixing the query to properly filter by status.
48-80: Excellent refactoring to consolidate community lookup logic.The refactoring successfully:
- Reduces multiple database queries to a single optimized lookup
- Centralizes ban checking logic
- Improves code maintainability and readability
- Properly handles edge cases (missing communities, deleted defaults)
This aligns perfectly with the PR's performance optimization goals.
Also applies to: 113-143
