Announcements Microservice Client SDK for Node.js
This is a Node.js client SDK for pip-services-announcements microservice. It provides an easy to use abstraction over communication protocols:
- HTTP client
- Seneca client (see http://www.senecajs.org)
- AWS Lambda client
- Direct client
Install
Add dependency to the client SDK into package.json file of your project
{
...
"dependencies": {
....
"pip-clients-announcements-node": "^1.0.*",
...
}
}
Then install the dependency using npm tool
# Install new dependencies
npm install
# Update already installed dependencies
npm update
Use
Inside your code get the reference to the client SDK
var sdk = new require('pip-clients-announcements-node');
Define client configuration parameters that match configuration of the microservice external API
// Client configuration
var config = {
connection: {
protocol: 'http',
host: 'localhost',
port: 8080
}
};
Instantiate the client and open connection to the microservice
// Create the client instance
var client = sdk.AnnouncementsHttpClientV1(config);
// Connect to the microservice
client.open(null, function(err) {
if (err) {
console.error('Connection to the microservice failed');
console.error(err);
return;
}
// Work with the microservice
...
});
Now the client is ready to perform operations
// Create a new announcement
client.createAnnouncement(
null,
{
category: 'maintenance',
title: { en: 'Maintenance on Jan 01' },
content: { en: 'Our servers will be shutdown for maintenance on Jan 01' }
},
function (err, announcement) {
...
}
);
// Get a random announcement
client.getRandomAnnouncement(
null,
{},
function(err, announcement) {
...
}
);
