limit-request-promise

library0.1.2jsnpmunverified

A rate-limited HTTP request library for Node.js built on top of request-promise. Version 0.1.2 is the only release, with no updates since. It provides per-domain request throttling with configurable max requests per time window. Unlike generic rate-limiters, it integrates directly with request-promise and manages request queues automatically. The library is lightweight but depends on the deprecated request package. Not recommended for new projects due to reliance on deprecated dependencies and lack of maintenance.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

LimitRequestPromise

✓ const LimitRequestPromise = require('limit-request-promise')

✗ import LimitRequestPromise from 'limit-request-promise'

Package only supports CommonJS require. ESM import will fail.

default export

✓ const LimitRequestPromise = require('limit-request-promise')

✗ const { LimitRequestPromise } = require('limit-request-promise')

The module exports a single constructor directly, not an object.

constructor options

✓ const lp = new LimitRequestPromise(1, 1)

✗ const lp = new LimitRequestPromise({max:1, sec:1})

Constructor takes two numeric arguments (max concurrency, delay in seconds), not an options object.

Creates a rate-limited request instance, configures per-domain limits, and sends a request.

const LimitRequestPromise = require('limit-request-promise'); const lp = new LimitRequestPromise(2, 1); // max 2 concurrent, 1 second delay lp.setup([ { host: 'http://www.example.com', max: 1000, sec: 60 } ]); lp.req('http://www.yahoo.co.jp') .then(console.log) .catch(console.error);

Debug

Known issues

deprecatedThis package depends on 'request-promise', which depends on the deprecated 'request' library. 'request' is no longer maintained and has known security issues.

fix

Use modern alternatives like 'got', 'axios', or 'node-fetch' with a rate-limiting wrapper.

affects: >=0.0.0

gotchaConstructor expects two numeric arguments: (maxConcurrency, delaySeconds). Passing an object or incorrect types may cause unexpected behavior.

fix

Use 'new LimitRequestPromise(2, 1)' for 2 concurrent requests with 1-second delay.

affects: >=0.0.0

gotchaThe 'setup' method must be called with an array of objects containing host, max, and sec properties. Missing or incorrect properties will cause errors.

fix

Call 'lp.setup([{ host: 'http://example.com', max: 1000, sec: 60 }])'.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: LimitRequestPromise is not a constructor

Using ES module import instead of CommonJS require.

fix

Use 'const LimitRequestPromise = require('limit-request-promise')'.

Error: Cannot find module 'request-promise'

Peer dependency 'request-promise' not installed.

fix

Run 'npm install request-promise'.

TypeError: lp.setup is not a function

Calling setup before creating an instance or misspelling method name (e.g., set up).

fix

Ensure you create an instance: 'const lp = new LimitRequestPromise(1,1); lp.setup([...])'.
