Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

OttoFeller Projen Templates

Test workflow status

📀 User guide

In order to install a certain project (template) from @ottofeller/templates call npx projen new in the dir of the new project in the following way:

# This will synthesize NextJS project in the current dir
npx projen new --from @ottofeller/templates ottofeller-nextjs

Update a project

In order to pull template updates you need to specify the desired version of the @ottofeller/templates package in either .projenrc.ts file or in package.json (if the version in .projenrc.ts is not fixed). Then run the default projen task:

npx projen

Upon completion the following changes would apply:

  • all packages with specified versions are updated (if a template does not specify a dependency version, it is not managed by projen and can be updated by simply setting the desired version in package.json; note that this way package-lock.json is not necessarily updated, thus you need to check it as well);
  • all projen-generated files are updated;
  • all sample code files are left unchanged (note that if you have deleted some sample code files they will be recreated unless you use the sampleCode: false option).

Install new or update existing packages

The common approach of installing packages by running npm install <package-name> won't work because npx projen re-synthesizes all files, including package.json. For dependency handling see the docs in projen repo:

To install a new packages to the project:

  • Add a new item with the package name to either the deps or devDeps array in project options. Alternative way would be to use project.addDeps('package-name') or project.addDevDeps('dev-package-name').
  • Run npx projen. This will update the package.json and lock file as well.

To update a packages already in the project:

  • Use the project methods addDeps and addDevDeps. E.g. in order to bump the dependency package-name@1 from the template one runs project.addDeps('package-name@2'), which effectively keeps the package and updates the version.

Note that there are two distinct approaches in controlling package version:

  • Strict version control in .projenrc.ts - when adding packages one specifies a name and a version. All updates are handled manually by specifying a new version and then running npx projen to resynthesize the project.
  • Specifying just a package name in .projenrc.ts. This is how projen recommends it. When no version is specified it makes it possible to update versions in package.json and package-lock.json without touching the .projenrc.ts file. It also allows the use of dependabot - otherwise all changes introduced by dependabot would be overwritten on npx projen.

Eject

To get rid of projen run this command:

npm run eject

The command removes default projen task, makes projen remove its authority from all the generated files and stop tracking changes. At this moment the project is managed as a regular repository (feel free to edit and remove files).

All the projen tasks are run via a custom runner, so the runner is saved into the project at scripts/run-task and the tasks remain in the project in a tasks definition file (.projen/tasks.json). All the internal tasks within the templates are saved as npm scripts and thus don't need this task runner. Therefore the task runner and the tasks definition file file can be deleted. If you had any custom tasks created in your project either use this runner or make sure to convert all the tasks into npm scripts before deleting the tasks definition file and the runner.

🛠 Development guide

Install

Simply install dependencies:

npm ci

Synthesize

The app itself is based on a projen template, so it can be synthesized (a code generated out of projen's TS files). Modify the app's template in .projenrc.ts and run the following command:

npx projen

:warning: Normally you should never modify anything other than templates in src/ dir and .projenrc.ts.

Build

The build is the process of creating JSII artifacts. These are the files required to run npx projen new --from ... (JSII is much more powerful technology, but it is out of the scope of this project). The build creates/updates the .jsii file (JSII config):

npx projen build

Publish

Publishing is a two-step process:

  • a GitHub action bumps version (creating a new commit with appropriate tag) and creates a draft release;
  • after the release is published another GitHub action builds the artifacts and pushes them to npm.

next.config.js

The config for NextJS is separated into two parts:

  • next.config.defaults.js - default config options deployed with the template; the file is readonly and shall not be edited;
  • next.config.js - editable config that by default only imports the next.config.defaults.js; feel free to edit the file, add required options, or include only the needed part of the default config.

UI packages

The project contains some UI-related packages:

  • tailwindcss (along with a few plugins);
  • postcss;
  • autoprefixer;
  • @headlessui/react.

These are included by default and can be excluded providing an isUiConfigEnabled: false option.

Tailwind

The template uses tailwind for CSS. There are two config files (similar to NextJS configuration):

  • tailwind.config.defaults.js - default config options deployed with the template; the file is readonly and shall not be edited;
  • tailwind.config.js - editable config that by default only imports the tailwind.config.defaults.js; feel free to edit the file, add required options, or include only the needed part of the default config.

Codegen config

The template uses @graphql-codegen packages for GraphQL management. The codegen config is copied from the assets folder (see the codegen.ts file). Feel free to edit the config.

In order to exclude the GraphQL packages from the project use the isGraphqlEnabled: false option. NOTE that the config file codegen.ts is editable and therefore not controlled by projen after creation. This means after GraphQL dependencies removal it remains in the project and should be deleted manually.

Codemods

Add src reference to imports

After update to [email protected] the typescript alias "*" : ["./src/*"] no longer works with jest/swc. The simplest solution is to get rid of the alias and update all imports - the codemod does exactly this. To run the codemod an npm script is added to the project: codemod:add-src-to-imports. The script run jscodeshift on src and pages folders. Feel free to add any arguments acceptable by jscodeshift.

Examples:

# Default: run the codemod on contents of src and pages folders
npm run codemod:add-src-to-imports
# Run the codemod in dry mode to see the extent of modification
npm run codemod:add-src-to-imports -- --dry

Playwright

A playwright based template for browser test projects.

npx projen new --from @ottofeller/templates ottofeller-playwright
# With options
npx projen new \
  ottofeller-playwright \
  --from @ottofeller/templates \
  --hasGitHooks=false \
  --lintPaths=src \
  --hasDocker=false \
  --hasDefaultGithubWorkflows=false

Options

For a list of available options see Common custom options.

SST

An SST based template for easy deployment of modern full-stack applications on AWS.

npx projen new --from @ottofeller/templates ottofeller-sst

npx projen new \
  ottofeller-sst \
  --from @ottofeller/templates \
  --hasGitHooks=false \
  --lintPaths=src --lintPaths=test \
  --hasDefaultGithubWorkflows=false \
  --initialReleaseVersion='1.0.0'

Options

initialReleaseVersion - the base version of the very first release; defaults to 0.0.1.

For other options see Common custom options.

Common custom options

The projects inherit from regular projen components and thus share the same options. In addition there are several custom options defined in this repository. The table below lists the custom options along with their per-project availability.

Option | apollo-server | backend-test | cdk | nextjs | playwright | sst ---|:---:|:---:|:---:|:---:|:---:|:---: hasDocker | ✅ | - | - | ✅ | ✅ | - hasGitHooks+ huskyRules | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ codeOwners | ✅ | - | ✅ | ✅ | ✅ | ✅ lintPaths | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ hasDefaultGithubWorkflows | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ hasRustTestWorkflow | - | - | ✅ | - | - | - isGraphqlEnabled | - | ✅ | - | ✅ | - | - isTelemetryEnabled+ telemetryOptions | ✅ | ✅ | ✅ | ✅ | ✅ | ✅

hasDocker

Include docker-related files such as .dockerignore, Dockerfile; defaults to true.

hasGitHooks

Include husky for git hooks management, defaults to true (NOTE: projen sets up git as a final step of project bootstrapping and thus there is no way to run husky install within the process. Hence a user has to run it manually after the git repo is initialized.).

huskyRules

Comes with hasGitHooks and defines rules to include:

  • checkCargo creates a pre-commit hook that runs a check on Rust cargo (disabled by default);
  • commitMsg creates a commit-msg hook for a basic check of commit messages (defaults to true); can be set to an object with ignoreBranches property which specifies an array of branch names to be ignored while processing commit messages; bu default (with commitMsg: true option) the ignoreBranches is set to ['main', 'dev']; in order to perform the check on all branches set either commitMsg: {} or commitMsg: {ignoreBranches: []};
  • huskyCustomRules adds arbitrary commands to supported hooks (commit-msg and pre-commit); disabled by default.

codeOwners

If defined, lists file patterns and corresponding owners for it to include into CODEOWNERS file.

lintPaths

An array of paths for linting and formatting.

hasDefaultGithubWorkflows

Include a default GitHub pull request template, defaults to true.

hasRustTestWorkflow

Include a default GitHub workflow for rust projects, defaults to false.

isGraphqlEnabled

Sets up GraphQL dependencies and supplementary scripts, defaults to true.

isTelemetryEnabled

Enables telemetry on the project.

telemetryOptions

With isTelemetryEnabled: true defines the following telemetry options:

  • reportTargetUrl - an endpoint URL for reporting; with the provided URL a script and a GitHub workflow are set up, which enables collection of some data about the project and sending it to the URL;
  • reportTargetAuthHeaderName - optionally defines Authorization header name for telemetry;
  • reportTargetAuthTokenVar - the name of env var to extract header value from; the value is expected to be stored in a CI secret.
