Package Exports

node-scc-config

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (node-scc-config) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Configure your Node.js applications using Spring Cloud Config

Benefits

Server and client data decryption

Installation

npm install node-scc-config

yarn add node-scc-config

Usage

Create a client-side pointer to the Spring Cloud Config service

const client = new SpringCloudConfigClient('your spring cloud config endpoint address...');

Configuring the client before calling

client
    .beforeLoad(s => ({
        your request options...
    }))

Configuring the client after the call

Chipher marker defaults to '{cipher}'

Chipher marker

client
    .afterLoad(d => d
        .setChipherMarker('your chipher marker...')

Data replacer by templates

Example: { ['{HOST}']: 'test', ['{SERVICE_NAME}']: 'app-service' }
```
client
    .afterLoad(d => d
        .setReplacer('your template...')
```

Data decryption

client

client
    .afterLoad(d => d
        .setDecryptor(new AesDecryptor('your secret key or password...')))

server

client
    .afterLoad(d => d
        .setDecryptor(new ServiceDecryptor('your decryption endpoint address...')))

Source preparation

Merge source

Default implementation if no function is specified

client
    .afterLoad(d => d
        .setMergeSource<AppServiceApiConfig>((configuration?: TConfiguration<AppServiceApiConfig>) => {
            your code to merge source...
        }))

Prepare source

Default implementation if no function is specified

client
    .afterLoad(d => d
        .setPrepareSource<AppServiceApiConfig>((source: Record<string, any>) => {
            your code to prepare source...
        }))

Call loading the configuration
```
await client.load();
```

Using the loaded configuration

type AppServiceApiConfig = {
    logLevel: string;
    options: {
        service: {
            url: string;
            login: string;
            password: string;
        };
    };
    testOptions: {
        url: string;
    };
};

const config = getConfiguration<AppServiceApiConfig>();
