Edge Node.js API Proxy Bundle with Firebase
How to setup Apigee in the middle between Apps and Firebase? This API Proxy provides the building blocks to get you started with a Express and Node.js App connected to Firebase leveraging official SDK. This Apps runs locally on your machine as well on Apigee Edge connected to a Database on Firebase.
Getting Started
Run and Deploy
Install dependencies and Run
$ npm install $ node index.js
Deploy to Apigee Edge
To deploy this API Proxy to Edge, make sure apigeetool is installed in your machine.
apigeetool deploynodeapp -n apigee-firebase-nodejs-express-ap i -d . -m index.js -o $YOUR_ORG -e test -b /apigee-firebase-nodejs-express-api -u $ae_username -p $ ae_password -VDeploy zip file
If you want to avoid installing apigeetool, you can also deploy with Edge UI apigee-firebase-nodejs-express-api.zip file with all artifacts in it. Make sure to edit target.xml with proper environment variables for Firebase./
Run
$ apiKey={GET_FROM_FIREBASE_CONSOLE}
authDomain={GET_FROM_FIREBASE_CONSOLE} databaseURL={GET_FROM_FIREBASE_CONSOLE} projectId={GET_FROM_FIREBASE_CONSOLE} messagingSende
rId={GET_FROM_FIREBASE_CONSOLE} node index.js
Test
Create Records in Firebase
app.post('/products', function (req, res) {
var ref = firebase.database().ref('/products');
var obj = [{
id: "123",
description: "Android Newborn Pacifier"
},
{
id: "345",
description: "Android Pixel"
},
{
id: "223",
description: "Chromecast Ultra"
}
];
res.send(ref.push(obj)); // Creates a new ref with a new "push key"
ref.set(obj); // Overwrites the path
ref.update(obj); // Updates only the specified attributes
})
Execute this command:
curl -X POST http://localhost:3000/products curl -X POST http://testmyapi-test.apigee.net/apigee-firebase-nodejs-express-api/products -d '' **Empty body, so Edge doesn\'t complain.**
Read records from Firebase
$ curl -X GET http://localhost:3000/products Returns: [{"description":"Androi`d Newborn Pacifier","id":"123"},{"description":"Android Pixel","id":"345"},{"description":"Chromecast Ultra","id":"223"}] #### Test in Edge $ curl -X GET http://testmyapi-test.apigee.net/apigee-firebase-nodejs-express-api/products
How to configure environment variables in Edge for Node.js
As security best practice you noticed that in order to protect from leaking credentials in your source code, we used process.env variables as below. Therefore, to set these variable, it is recommended to leverage EnvironmentVariables from TargetEndpoint in the next section.
var config = {
apiKey: process.env.apiKey,
authDomain: process.env.authDomain,
databaseURL: process.env.databaseURL,
storageBucket: process.env.storageBucket,
messagingSenderId: process.env.messagingSenderId
};
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<TargetEndpoint name="default">
<ScriptTarget>
<EnvironmentVariables>
<EnvironmentVariable name="apiKey">{REPLACE_ME}</EnvironmentVariable>
<EnvironmentVariable name="authDomain">{REPLACE_ME}</EnvironmentVariable>
<EnvironmentVariable name="databaseURL">{REPLACE_ME}</EnvironmentVariable>
<EnvironmentVariable name="projectId">{REPLACE_ME}</EnvironmentVariable>
<EnvironmentVariable name="messagingSenderId">{REPLACE_ME}</EnvironmentVariable>
</EnvironmentVariables>
<ResourceURL>node://index.js</ResourceURL>
</ScriptTarget>
</TargetEndpoint>Did it work for you or not? Please post your comments here.
