@wroud/flow-middleware/lib/FlowMiddleware.js

A lightweight middleware management library for JavaScript and TypeScript, facilitating middleware chains with re-runs, error handling, and disposability.

import { MiddlewareRequest } from "./MiddlewareRequest.js";
export class FlowMiddleware {
    logger;
    middlewares;
    errorMiddlewares;
    constructor(logger) {
        this.logger = logger;
        this.middlewares = [];
        this.errorMiddlewares = [];
    }
    use(...middleware) {
        this.middlewares.push(...middleware);
        return this;
    }
    error(...errorMiddleware) {
        this.errorMiddlewares.push(...errorMiddleware);
        return this;
    }
    createRequest(initialData = {}) {
        return new MiddlewareRequest([...this.middlewares], [...this.errorMiddlewares], initialData, this.logger);
    }
}
