Firebase database triggers and Rest API in same project? - firebase

Question

I have a Firebase cloud function project that I recently updated all the functions.https.onRequest to run through Express to create a REST API service. The APIs work fine. But when I try and deploy the project, none of the previous Firebase database triggers are deployed anymore (Example: CalculateMyStats trigger worked fine, but was removed from my cloud functions list) . Only the rest function is deployed now. Is it possible to have Rest API's and triggers in the same project?
index.ts
import * as admin from 'firebase-admin';
import * as functions from 'firebase-functions';
import * as http from './http';
import { AddLocationIOBookMarks, DistrubuteNotificationData, NewUserEmail } from './users/usersFuncModules';
import { AutoCheckoutCron } from './locations/locationsFuncModule';
import { CalculateMyStats } from './rating/ratingFuncModule';
import { FIREBASE_CONFIG } from './config/firebaseConfig';
import { LocationsUserCount } from './pushNotifications/pushFuncModule';
export { AddLocationIOBookMarks, DistrubuteNotificationData, NewUserEmail };
export { AutoCheckoutCron };
export { CalculateMyStats };
export { LocationsUserCount };
admin.initializeApp({
credential: admin.credential.cert({
projectId: FIREBASE_CONFIG.project_id,
clientEmail: FIREBASE_CONFIG.client_email,
privateKey: FIREBASE_CONFIG.private_key
}),
databaseURL: FIREBASE_CONFIG.databaseURL
});
admin.firestore().settings({ timestampsInSnapshots: true });
exports.rest = functions.https.onRequest(http.endpoint);
ratingFuncModule.ts
import * as express from 'express';
import * as functions from 'firebase-functions';
import * as http from '../http';
import * as myStatsModule from './calculateMystats';
import * as ratingModule from './rateUser';
import { fsConst } from '../firestoreConst';
const rateRoute = express.Router();
const cors = require('cors');
const corsOptions = http.corsOptions;
export const CalculateMyStats = functions.firestore.document(`${fsConst.USERRATINGS}/{doc-id}`).onWrite((change, context) => {
const ratedUser = change.after.data();
return myStatsModule.roundAllMyStats(ratedUser.userId).catch(error => {
console.error(new Error(error), `| Method: CalculateMyStats`);
});
});
rateRoute.get('/rate/updateRating', cors(corsOptions), (req, res) => {
const currentUserId = req.query.currentUserId;
const toBeRatedUserId = req.query.toBeRatedUserId;
const rateDocId = req.query.rateDocId;
const rateFormValues = req.query.rateFormValues;
ratingModule
.rateCurrentUser(currentUserId, toBeRatedUserId, rateDocId, rateFormValues)
.then(data => {
if (rateDocId !== 'undefined') {
res.send(JSON.stringify(rateDocId));
} else {
res.send(JSON.stringify(data));
}
})
.catch(error => {
console.error(new Error(error), `| Method: updateUserRating`);
});
});
// Export all routes for rating related http request
module.exports = rateRoute;
firebase.json
{
"functions": {
"predeploy": [
"npm --prefix $RESOURCE_DIR run lint",
"npm --prefix $RESOURCE_DIR run build"
],
"source": "functions"
},
"hosting": {
"public": "public",
"rewrites": [{
"source": "/api/v1/**",
"function": "rest"
}],
"ignore": ["firebase.json", "**/.*", "**/node_modules/**"]
}
}
And when I deploy:
firebase deploy --only functions

You have to export all your trigger functions alongside your exports.rest in index.ts like so:
import { CalculateMyStats } from './rating/ratingFuncModule';
exports.rest = functions.https.onRequest(http.endpoint); // your existing export
exports.calculateMyStats = CalculateMyStats // trigger function export
