How to also update the package.json version when using yarn update

If you run yarn update on a package, yarn will update the package and your yarn.lock file. This is totally fine. As long as you check in your lock file, your developers and team will all have the correct versions of libraries when they run yarn install.

However it will not update the package.json with the new semver for the package. I kind of found this annoying, if only for aesthetic reasons I wanted to quickly see which minimum versions of packages I was using in package.json.

To have yarn also update the semver in your package.json there are a couple of options. Essentially you need to add —latest

Using —latest

If you pass yarn the --latest flag it will update the package.json.

NOTE: this will not respect semver and will update to the latest version. Whatever that might be.

yarn upgrade @graphql-codegen/cli --latest

Using interactive upgrade —latest

If you use the interactive upgrade it will also upgrade the package.json for you

yarn upgrade-interactive --latest

Specify use an exact version —exact

It’s a good idea to specify a specific version of the package so that deploying on CI will have the exact same versions as on your dev env. Your lock file will help with this too but being specific with versions is a good idea.

yarn upgrade @graphql-codegen/cli --latest  --exact

Running a NodeJS app with Postgres in Dokku

I have some side projects that don’t see much traffic so I run them on a 5$ Digital Ocean droplet running Dokku.

Dokku is an open source Heroku-like platform. It’s super easy to create and maintain multiple applications on a Dokku instance. It’s perfect for solo makers.

There are plugins for most of the common services you might want like PostgreSQL or Redis.

Here’s what we’re going to do

  1. A Brief overview of Dokku
  2. How to get a Dokku instance running
  3. Create a new Dokku application
  4. Add a database service
  5. Expose the database for debugging and testing (Optional)
  6. Add a domain to the application
  7. Add any configuration variables for your application
  8. Add SSL to the application
  9. Add the Dokku remote to your application
  10. Push your application to Dokku
  11. Maintaining your Dokku server

Semantic versioning javascript projects but skipping NPM publish

If you want to use semantic versioning and automate release versions using semantic-release for your front-end client application you probably don’t want to actually publish it to npm.

Here is how to use semantic-release while not releasing to npm.

Avoid these issues when using new ECMAScript modules in your Node.js application

ECMAScript modules are the official standard format to package JavaScript code for reuse in the future. Es6 modules now have full support in Node.js 12 and above so it’s time to start using them.

JavaScript developers and node libraries have typically used commonjs for modules up to now. If you’ve used typescript in the past few years you will be familiar with the module import syntax in you application. Instead of commonjs require("module") most typescript applications use some variation of import module from "module".

Typescript will then transpile this import syntax into commonjs require statements for you. This step is not necessary in modern Node.js applications. You can just use import module from "module" directly in your transpiled code.

If you use typescript you can change just change your tsconfig settings to output ECMAScript es6 modules and you will be good to go. If you don’t use typescript you might have to do some rewriting if you want to get your app updated.

Here are solutions to the issues that took me a bit of time and investigation to figure out when I was upgrading my Node.js application to use ECMAScript modules like configuring typescript, setting up jest, configuring the package.json correctly and more.
