  • react-app-rewired

    Override create-react-app webpack configs without ejecting

    Project mention: Accepting Crypto Payments in a Classic Commerce App | | 2022-07-05

    Heads up: CRA5 bumped their webpack dependency to a version that no longer supports node polyfills in browsers. This breaks the builds of nearly all Ethereum-related projects today. A common workaround that avoids ejecting is to hook into the CRA build process. We’re using react-app-rewired but you could simply stay at CRA4 until the community comes up with a better solution.

  • node-config

  • jsonnet

    Jsonnet - The data templating language

    Project mention: Falling for Kubernetes | | 2022-08-09

    > As an aside, the existence of the '{{ | indent 4 }}' function in helm should disqualify it from any serious use. Render, don't template.

    This. My first thought when I saw the indentation hack was "it can't be a serious, production-ready software".

    My take on this is as follows.

    If you have a simple use case, write your K8s manifests directly.

    If you have a complex use case, Helm is often more pain than its worth. Use alternatives, for example Jsonnet[0] with kubecfg[1]. Or emit manifests from your language of choice. Just don't use Helm.

    Project mention: Turn a Markdown blog to a simple SSG | | 2022-07-30

    Over the past few weeks, I mostly wrote on how to template a Node.js application with EJS using Express.

Today, I'll combine those tutorials to turn the Markdown blog, from the last tutorial, into a simple SSG.

    Project mention: What's the best practice to fetch 10 random images from Cloud Storage to display to users? | | 2022-04-08

    However, if you have plans to increase the number of images, like to 500 for example, then I'd suggest using server-side pagination here. I'd also suggest using cursor-based pagination instead of offset-based for better performance. Github uses cursor-based pagination on stargazers page since the number of stars can get potentially huge for a repo.

  • koanf

    Simple, lightweight, extensible, configuration management library for Go. Support for JSON, TOML, YAML, env, command line, file, S3 etc. Alternative to viper.

    Project mention: Viper – Go Configuration with Fangs | | 2022-05-20

    Use viper with care. It has some dangerous fundamental flaws [1]. We got bitten hard, submitted a PR [2] and followed up for a year and a half to no avail, before I went ahead and reinvented the wheel and wrote koanf (plug), specifically to avoid viper's flaws.

    Most importantly:

    - Breaks JSON, YAML, TOML etc. language specs by forcibly lowercasing all keys internally. Dangerous because it can silently merge differently cased config keys into lowercase.

    - Hard codes big unnecessary dependencies into the core, significantly bloating build sizes. No separation or abstraction.

    info on XDG: [the XDG spec](

    tools that respect XDG, for fellow JS CLI developers:

    - Find and load configuration from a package.json property, rc file, or CommonJS module. [Check `searchPaths` to implement XDG spec compliance.](

    - Sindre's libraries use [`env-paths`]( to get paths compliant with this.

    - simple config storing (maybe try [conf-cli]( to manipulate if needed) the successor to [configstore](

    - conf like datastore but in the shclinkerverse
