Node.js: Target Active LTS + Harden npm Installs with .npmrc

Notes from setting up a fresh Node/TypeScript project in mid-2026 — grounded in the actual package.json/.npmrc of a real repo, not generic advice.

Which Node version to target

As of mid-2026:

1. Search for photo by viewing on unsplash.com and finding ID in URL. For example https://unsplash.com/photos/photo-of-green-leafed-plants-QKo-op_gR9I which has ID QKo-op_gR9I
2. Grab your access key from Unsplash API dashboard: ACCESS_KEY_GOES_HERE
3. Grab JSON file by plugging in ID and client_id into API so URL looks like this: https://api.unsplash.com/photos/QKo-op_gR9I?client_id=ACCESS_KEY_GOES_HERE
4. Pull out the regular size URL from the JSON in "urls > regular" key (which is 1080 wide) and use that in the site

Goals

• Primarily highlight content author. Inlude a PFP image, name, organization name and a link to their personal site.
• Secondarily highlight all reviewers and contributors
• Link to a specific topic on Peeranha forum so users can ask questions and have discussions. For example Lesson 4: Testing your TierNFT would point to Testing Solidity contracts topic in Peeranha.

Other goals:

• Create a consistent header and footer to use for all content tracks and fundamentals
• Add a general link to our Peeranha community in Footer and Getting Started - https://developerdao.peeranha.io

Local setup to verify your Git Commits

Follow instructions here: https://gist.github.com/Beneboe/3183a8a9eb53439dbee07c90b344c77e

Import GitHub webflow key

When you merge commits via GitHub UI (say "squash and merge"), GitHub will sign the commit itself.

Import GitHub webflow key so key is verified when you run git log --show-signature

These worked for me locally:

encrypt:

cat tshirt.png | openssl enc -aes-256-cbc -a -salt -p > test.enc

decrypt:

cat test.enc | openssl aes-256-cbc -d -a -out tshirt2.png

What if you want to debug the Rust program itself in Anchor?

1. In Rust, add msg!("Some variable: {:?}", variable);
2. Run anchor test to run the program through the tests. However you won't find the output there.
3. View the output instead in a file within your program-logs folder in your Anchor project. It'll be recreated each time you run the program.

This is subtly mentioned in the docs and can be found in the CLI docs here: https://book.anchor-lang.com/chapter_4/cli.html#test

The https://github.com/Developer-DAO/pixel-avatars project has a non-standard place for the contracts so the OpenZeppelin imports are shown with a red lint error.

For Solidity VSCode plugin, set "Package Default Dependencies Directory" to contract/node_modules instead of default node_modules.

VSCode can then find the OpenZeppelin imports.
