@Transactional

Translations: 简体中文

@Transactional is a package created to solve the problem of transaction delivery in nodejs code can only rely on parameter passing between functions. Now, we use the decorator (annotation) to pass.

Use immediately:

import { Transactional } from 'transactionaljs'

class UserService {
	@Transactional()
	public async createUser(){}
}

Immediate test:

npm install
npm run test

Features:

 

• Non-intrusive: Put @Transactional() on any function and get powerful transaction functions automatically;
• Multiple modes: REQUIRED, SUPPORTS, REQUIRES_NEW, NEVER, NOT_SUPPORTED (plan support);
• Multiple data sources: Any database that supports transaction creation, transaction commit, transaction rollback, can be used, such as mysql, mongodb, etc.
• ORM friendly: Just need to inject multiple transaction methods into the TransactionalPlatform, you can easily complete the transaction takeover, SequelizeV4 injection only requires 9 lines of code;
• Test enrichment: The current unit test has reached 66.67% coverage, and our plan is 100% forever;
• Typescript : written entirely using typescript;
• One-click test: npm run test, download source code, does not require any external dependencies, as long as npm nodejs directly open the test;
• Open source free: Welcome to submit PR, forever MIT agreement;

Roadmap:

 

• Distributed transaction: I haven’t thought about it yet, probably based on 2PC;
• Multiple data sources: Support mongodb, mysql, redis transaction chain;
• More tests: More unit tests;
• More mode support: Modes such as NOT_SUPPORTED, and iterations of other modes;
