NVM and .nvmrc Management Guide

A comprehensive guide for managing Node.js versions across projects using nvm and .nvmrc files.

What is nvm?

Node Version Manager (nvm) allows you to install and switch between multiple Node.js versions on the same machine. This is essential for:

• Working on projects that require different Node versions
• Testing applications across Node.js versions
• Avoiding "works on my machine" issues in teams

Integrating Librechat

Connecting Librechat and Ollama

1. First, follow the official LibreChat instructions to update your librechat.yaml file in the base directory.

2. (unclear if needed) Set the environment variable launchctl setenv OLLAMA_HOST "0.0.0.0:11434" to expose the ollama API before ollama serve, per this github issue

3. Set the volume to your docker-compose.override.yml for Librechat (under the service named api):

services:

Default Formatter in VS Code

VS code will ask you the first time but if you make the wrong choice or want to change it, here's how you change it:

1. Access the Command Palette by pressing Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (Mac).
2. Type and select "Format Document With..." from the command palette.
3. At the bottom of the list, click on "Configure Default Formatter...".

To test, on a file use Alt-Shift-F to format.

Note for Vue: Use "Vue Official", it works better than Prettier.

In some cases I'd like the marked library open links in new tabs, but the default behavior is to open in the same tab. This means you have to override then renderer but the documentation doesn't make it completely obvious how to do that. Here's how you can do it.

// src/utils/markdown.ts
import { marked } from "marked";
import type { Token, Tokens } from "marked";

export const renderMarkdown = (content: string) => {
  try {
 const renderer = new marked.Renderer();

Often I'll find it helpful to give a LLM context of my file structure for coding projects, so I co-wrote this script to only grab the relevant files and output them in a nicely formatted tree.

It ignores common directories in a VS code (Nuxt and Vue) project and in a Pycharm (Python) project. It also only grabs files with approved extensions.

Wouldn't it be nice if Powershell could simulate history | grep "alembic"? Now it can.

Place this in your Powershell profile (PS> $PROFILE to find the path)

function Get-CommandHistory {
    param (
        [string]$Pattern = "*"
    )
