Configure your Node.js applications using Spring Cloud Config


Benefits

* Server and client data decryption

Installation

``shell
npm install node-scc-config
`
`shell
yarn add node-scc-config
`

Usage

1. Create a client-side pointer to the Spring Cloud Config service
`ts
const client = new SpringCloudConfigClient('your spring cloud config endpoint address...');
`

2. Configuring the client before calling
`ts
client
.beforeLoad(s => ({
your request options...
}))
`

3. Configuring the client after the call
> Chipher marker defaults to '{cipher}'
* Chipher marker
`ts
client
.afterLoad(d => d
.setChipherMarker('your chipher marker...')
`
* Data replacer by templates
> Example: { ['{HOST}']: 'test', ['{SERVICE_NAME}']: 'app-service' }
`ts
client
.afterLoad(d => d
.setReplacer('your template...')
`
* Data decryption
* client
`ts
client
.afterLoad(d => d
.setDecryptor(new AesDecryptor('your secret key or password...')))
`
* server
`ts
client
.afterLoad(d => d
.setDecryptor(new ServiceDecryptor('your decryption endpoint address...')))
`
* Source preparation
* Merge source
> Default implementation if no function is specified
`ts
client
.afterLoad(d => d
.setMergeSource((configuration?: TConfiguration) => {
your code to merge source...
}))
`
* Prepare source
> Default implementation if no function is specified
`ts
client
.afterLoad(d => d
.setPrepareSource((source: Record) => {
your code to prepare source...
}))
`
3. Call loading the configuration
`ts
await client.load();
`

4. Using the loaded configuration
`ts
type AppServiceApiConfig = {
logLevel: string;
options: {
service: {
url: string;
login: string;
password: string;
};
};
testOptions: {
url: string;
};
};

const config = getConfiguration();
