Morphix

Micro templating with function pipes support

🚀 Getting Started

This package is available in the Node Package Repository and can be easily installed with npm or yarn

$ npm i @sigyn/morphix
# or
$ yarn add @sigyn/morphix

📚 Usage

import { morphix } from "@sigyn/morphix";

await morphix("Hello {name | capitalize}", { name: "john" });

Important

morphix() is asynchrone because it supports async functions

🌐 API

morphix

async function morphix(
  template: string,
  data: Record<string, any> | unknown[],
  options: MorphixOptions = {}
): Promise<string>

template Type: string

Text with placeholders for data properties.

data Type: object | unknown[]

Data to interpolate into template.

The keys should be a valid JS identifier or number (a-z, A-Z, 0-9).

Options

type MorphixFunction = (value: string) => Promise<string> | string;

export interface MorphixOptions {
  /**
   * Performs arbitrary operations for each interpolation.
   * If the returned value is undefined, the behavior depends on the ignoreMissing option.
   * Otherwise, the returned value is converted to a string and embedded into the template.
   */
  transform?: (data: { value: unknown; key: string }) => unknown;
  /**
   * By default, Morphix throws a MissingValueError when a placeholder resolves to undefined.
   * If this option is set to true, it simply ignores the unresolved placeholder and leaves it as is.
   *
   * @default false
   */
  ignoreMissing?: boolean;
  customFunctions?: Record<string, MorphixFunction>;
}

Note

MissingValueError is exported, which is useful for instance and type checking.

📦 Functions

capitalize

Capitalize the first letter.

dnsresolve

Retrieve host of a given IP. It uses dns.reverse.

If it fails to retrieve the host, it returns the ip instead.

Adding custom functions

Morphix lets you inject your own custom functions.

import { morphix } from "@sigyn/morphix";
import assert from "node:assert";

const transformedData = await morphix(
  "{ data | lower }",
  { data: "HELLO WORLD" },
  {
    customFunctions: {
      lower: (value) => value.toLowerCase()
    }
  }
);
assert.strictEqual(
  transformedData,
  "hello world"
);

Credits

This package is heavily inspired by pupa. Morphix is a fork that includes function support and does not support HTML escape.
