i18next-select-post-processor

Introduction

A conditional ability that make i18next more powerful.

Getting Started

# npm package
$ npm install i18next-select-post-processor

Usage

We could using Boolean, String, Number, and Null type to check values.

import i18next from 'i18next';
import SelectPostprocessor from 'i18next-select-post-processor';

i18next
  .use(SelectPostprocessor)
  .init(i18nextOptions);

const translation = {
  example: {
    basic: `$s(female,true,She is a lady.);`,
    nesting: `$s(cond1,true,She $s(cond2,true,is $s(cond3,true,a $s(cond4,true,lady.););););`,
    concatenation: `$s(cond1,true,She );$s(cond2,true,is );$s(cond3,true,a );$s(cond4,true,lady.);`
  }
};

i18next.t(example.basic, { "postProcess": "select" });
// => She's a lady.
i18next.t(example.nesting, {"postProcess": "select", "cond1": true, "cond2": true, "cond3": true, "cond4": true});
// => She's a lady.
i18next.t(example.concatenation, {"postProcess": "select", "cond1": true, "cond2": true, "cond3": true, "cond4": true});
// => She's a lady.

});
