In Javascript, how can I dynamically construct a path within a require()?-CodePudding

I've got an environment file.

Like the title says, I want to build the path for my images based on the config setup, like so :

const images = {
      logo: require(`./${Config.BRAND}/images/logo_${Config.BRAND}.png`)
    };

Unfortunately, it does not work.

Is there any other way to achieve it ?

CodePudding user response：

You should avoid using dynamic requires as it has bad consequences.

Metro bundler will not package unused images and dynamic require makes it hard to detect.
It is covered in the official documentation: React Native - Static Image Resources
It is also generally not advised by ESLint: eslint-plugin-import/no-dynamic-require

You can use if-else (or simply ternary) or switch statement to get the image you want to use.

const images = {
  logo: Config.BRAND === 'brand1' ? require(`./brand1/images/logo_brand1.png`) : require(`./brand2/images/logo_brand2.png`);
};

Create a .env file in the root of project. Put dynamic brand there.

BRAND=Your_dynamic_link

install than import dotenv module

require('dotenv').config()

Than you can access that environment

const images = {
  logo: require(`./${process.env.BRAND}/images/logo_${process.env.BRAND}.png`)
};
