Hello guys, welcome to the 10th session of the EPA da da tutorial for beginner. In this session we will see how to create a web hook using the Node JS and deployed on a Google Cloud. For this I am already installed the Node JS and the NPM on my system and I created a new directory. Here is a file which contains some basic setting up for the Node JS environment. For this I'm going to use the X rays and the body parser to retrieve the data from the body of the request, I am not Node JS expert you may know the another way to perform the same operation. Here I am specify that the URL encoding will be the extended its length will be the up to 100 kB And also set a limit for the Jason had come in the request.
At the end listen the app for these will require the port number not that you must need to do to the port number from the process dot and dot port for the Google Cloud, how are India locrian moment it was not available, so we can use the 080 for that. Along with these I am also created the package dot JSON file in which to specify the some basic details about the app and add the dependencies are not always a must be greater than 4.3 point two. To specify the command in the script, add the extras in the dependency and Google Cloud tool in the dependency Let creator out and return the sum up to number for that right app dot post slayers can see in the past the year function which take the two parameter, the first will be a request and should be the resource and literal the parameter for that right the pair meters equal to request or to pour the door reserved a lot parameters and check if parameters door number one, not equally cool, define and parameters all for now.
To not equal equal undefined then we are going to perform the opposite. In general the speech well that I am using the backcourt right the sum, or we within the curly braces specify the parameters of someone. And again, poly braces when they're specify the parameters dot num two is Doris sign curly braces. And here we need to convert those number to the integer before performing the operation. For that write the parsing. Within that write the parameters door number one plus bus seemed Within the passing the num to accommodate the backcourt for the better readability I am like from the here and then we will return the response with the status 200 there stands for okay and send the response which contain the speech, speech and the display Tex.
It will be also speech and call the enemy method and say which route is created. Now I am going to teach in the local environment. For this open the command prompt Before starting over F, we need to install the dependency packages for that write the npm install, Express. And npm install body parser. After installing both we need to start the application. For that we need to write the node.js you can see that our app is listening on port number 800.
So let's test it by sending the request from the postman or change to the TV core four slash four slash localhost colon eight ID 0804 says Kelsey, send it Here we got the response. Along with that we also got the new line and the deputy because we are specified here. We need to remove it, save it, quit, start it again. Send it again, we got the proper output. Now we need to deploy it only a good workflow. For this, we need to create the demo file.
The within that we just need to specify the runtime here and then we'll be the nauseas and and environment will be the flex say wait please In the command from and right, G Cloud any reinitialized use the same account. Same project. I'm not going to configure the computer engine so no right G Cloud App deploy. And yes, we want to deploy this URL for app is a deploy on the Node JS environment. To view the pinky browser when you try the G Cloud. Browse.
Here we got the server error server encounter, the temporary error could not complete your request. Let's try to open the studio to Qt 502 server error. I don't know what's happening here. But the way for deploying the Node JS app on the cloud is the same. I will make the edit on the Google Cloud for the same issue and upload the video if I got the any solution for that. Let's see what we learned in this lesson.
First of all, we created the route in which we retrieved the two number from the request body. For this we need to use the body parser Then we created the method that we want to return and assign it with the 200 code. And here is the package dot JSON in which we are specify the dependency details. In the ab.ml file we are just specify the runtime for the OBD. No GS and environment is a flex. Thanks for watching.
Have a nice day.
