p-map

What it is

p-map is a utility that allows developers to map over an array of promises concurrently. This tool simplifies handling asynchronous operations in JavaScript, making it easier for developers to manage and process multiple promises at once.

p-map stands out as a lightweight, easy-to-use library that simplifies the process of handling multiple promises concurrently in JavaScript applications.

When it fits — and when it doesn’t

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited error handling

   p-map does not provide built-in mechanisms for aggregating errors from failed promises, requiring developers to implement custom error handling logic.

2. 02

   Concurrency control is rudimentary

   The tool allows setting a concurrency limit but lacks advanced options such as dynamic throttling based on system performance or promise resolution times.

3. 03

   No built-in support for cancellation

   p-map does not provide a mechanism to cancel running promises, which can be critical in scenarios where operations need to be stopped mid-execution.

What it does well

• Concurrent mapping over promises

• Simplified handling of asynchronous operations

• Easy to integrate into existing JavaScript projects
