Addressing the issue of .pnpm-store being created in the project root in Devcontainer

README.md

What to do when .pnpm-store is created in the project root

When I tried to use pnpm with devcontainer, a .pnpm-store was created in the project root. It should normally be created in an appropriate path under the home directory.

This directory contains the npm package entities. My understanding is that this is a characteristic of pnpm and it is not in line with pnpm's philosophy to create it in the project root.

Solution

Explicitly specify store-dir in pnpm.

pnpm config set -g store-dir "${HOME}/.local/share/pnpm/store"

Set postCreateCommand in devcontainer.json to run this after devcontainer creation.

// .devcontainer/devcontainer.json

{
// ...
  "postCreateCommand": ".devcontainer/postCreate.sh",
// ...
}

Contents of .devcontainer/postCreate.sh.

# .devcontainer/postCreate.sh

#! /usr/bin/env bash

pnpm config set -g store-dir "${HOME}/.local/share/pnpm/store"
pnpm install
