fpk

Functional configuration management.

Use Typescript / Javascript to generate yaml, json, ini (or register your own format) configuration. Could be used for:

• Generating configuration for Kubernetes
• Generating configuration for databases
• etc.

Why?

Functional programming and Typescript have some great traits, which are also really beneficial when writing configuration:

• Composition - you can build your configuration like lego.
• Re-usability - create functions that define entire workloads and reuse them across projects.
• Type checking - intellisense FTW.

Packages

Kubernetes Example Project

See https://github.com/tim-smart/fpk-k8s-example

Basic Usage

Create some configuration

src/my-app.ts

export default {
  "00-one": {
    key: "value",
  },

  "02-two": {
    foo: false,
  },

  "03-three.json": {
    json: true,
  },

  "04-four.ini": {
    ini: "yes",
  },
};

Generate the output

$ fpk -d src -o out
MKDIR my-app/
CREATE my-app/00-one.yaml
CREATE my-app/02-two.yaml
CREATE my-app/03-three.json

$ tree out/
out
└── my-app
    ├── 00-one.yaml
    ├── 02-two.yaml
    ├── 03-three.json
    └── 04-four.ini

1 directory, 4 files

$ cat out/my-app/00-one.yaml
