Sample Node JS application with GraphQL
This is a sample GraphQL
implementation over the NodeJS
express
server listening on port 4000.
The data for this server if feed by the hardcoded file in here. This data is used for only reading i.e., only by the query
type.
Via mutation
, whatever data is sent to the server; all of those are stored in the server session and returned to the query
while upon reading.
Requirements
- node
- npm
- docker (for containerizing the app)
- docker registry account
- k8s minikube (for deploying the container into cluster)
- kubectl (to interact with the Kubernetes)
Install & Run in k8s
Follow the below steps to download and run the application in minikube.
Download the source code
git clone https://github.com/gkarthiks/nodeJS-GraphQL.git
Build the source code and run it locally for testing.
cd nodeJS-GraphQL npm run-script build npm run-script run
The above steps will run the nodeJS
application listening on port 4000. try hitting localhost:4000/graphql
Noe create a docker image
by executing the below command.
docker build -t graphqlexample .
This will create a docker image with node:slim
as base. Check whether the image is created or not by listing the docker images via below command.
docker image ls
Tag the docker image with the following command and push it to your docker hub.
docker tag graphqlexample <username>/graphqlexample docker push <username>/graphqlexample
Find quick docker commands here.
Now that docker image is created, that can be tested with docker itself by runing it locally with the below command.
docker run -p 4000:4000
/graphqlexample
Once after successfull testing, it can be deployed in the minikube
by creating the Deployment
, Service
and Route
objects.
