@jsplumb/docusaurus-plugin-env-loader-json

env-loader-json

This Docusaurus plugin loads configuration from a JSON file and sets the given values in the customFields section of the Docusaurus siteConfig. It is designed to run both in development mode (ie docusaurus start) and in production mode.

The current environment is read from the NODE_ENV environment variable, which is development when running the dev server and production when running a build.

Installation

npm i --save-dev @jsplumb/docusaurus-plugin-env-loader-json

Setup

Add the plugin to the plugins section of docusaurus.config.js:

plugins:[
    ...,
    "@jsplumb/docusaurus-plugin-env-loader-json",
    ...
],

By default, the plugin will look for a file called env.json in the Docusaurus project directory. You can change the name of the file the plugin looks for via the sourceFile option:

plugins:[
    ...,
    [
        "@jsplumb/docusaurus-plugin-env-loader-json",
        {
            "sourceFile":"aFolder/myEnv.json"
        }
    ]    
    ...
],

Note that the path to the file is resolved relative to the Docusaurus project directory - a leading slash is not required.

Configuration

Inside the environment config file, you should declare a section for each environment:

{
    "production":{
        "SERVER_URL":"https://some.server.com/anEndpoint"
    },
    "development":{
        "SERVER_URL":"http://localhost:4200/anEndpoint"
    }
}

Accessing values

You can access these values via the customFields section of the Docusaurus site config:

import useDocusaurusContext from '@docusaurus/useDocusaurusContext';

export function MyApp {

    const {siteConfig} = useDocusaurusContext();
    const serverUrl = siteConfig.customFields.SERVER_URL

    ...

}
