Fixing Issues Using npm & pnpm in an Astro Project

Introduction

Using both npm and pnpm in a single project can lead to various issues, especially when managing dependencies in an Astro project. This tutorial outlines the problems you might encounter and provides a step-by-step solution to resolve them.

Common Issues When Using npm and pnpm Together

1. Conflicting Lock Files:

   • Both npm and pnpm create their own lock files (package-lock.json for npm and pnpm-lock.yaml for pnpm). This can cause conflicts and inconsistencies in your project’s dependencies.

2. Duplicate Dependencies:

   • Using both package managers can lead to duplicate installations of dependencies, increasing the size of your node_modules folder and potentially causing version mismatches.

3. Node Modules Resolution:

   • pnpm uses a different strategy for storing node modules, which can result in issues when npm expects them to be in a standard layout.

Simple Solution to Avoid Issues

To avoid these issues, you can follow these steps:

Step 1: Move the Astro Node Folder

Move the Astro node folder into a subfolder within node_modules named .ignored. This helps to segregate the dependencies and avoid conflicts.

mv node_modules/astro node_modules/.ignored/astro

Step 2: Run pnpm Install

Next, install the dependencies using pnpm to ensure consistency in the dependency management.

pnpm install
