This is a blank project for CDK development with TypeScript.
The cdk.json
file tells the CDK Toolkit how to execute your app.
npm run build
compile typescript to jsnpm run watch
watch for changes and compilenpm run test
perform the jest unit testscdk deploy
deploy this stack to your default AWS account/regioncdk diff
compare deployed stack with current statecdk synth
emits the synthesized CloudFormation template
cdk bootstrap aws://837984857695/us-east-1
npx npm-check-updates -u
and then run
npm install
This will solve the error of
https://docs.aws.amazon.com/cdk/v2/guide/environments.html
cdk synth stackid1
cdk deploy stackid2
First install the dependency
npm install ckd-dia
Then install Graphviz for Mac
brew install graphviz
First synth the project then run the following command
npx cdk-dia
or for an interactive html
npx cdk-dia --rendering cytoscape-html
const vpcId = process.env.VPC_ID;
if (!vpcId || !isValidVpcId(vpcId)) {
throw new Error("Please provide a valid VPC_ID environment variable");
}
axios.get("https://someconfig.mycompany.com/dev").then((devConfig) => {
const app = new App();
const stack = new DbStack(app, "DevDb", results);
app.synth();
});
But if the results are not given properly we can face trouble.
So what we can do is we can create a config loader file named refreshConfig.js
axios.get("https://someconfig.mycompany.com/dev").then((devConfig) => {
fs.readFileSync("./env/dev.json", devConfig);
});
ANd create an npm script for that.
{
"scripts": {
"refresh:config": "node refreshConfig.js"
}
}
We can use the cdk.json
file to change the context values to provide values for different environments
If only the code of the lambda changes we don't want don't need to re-deploy the whole thing. In these cases we can just update the function without changing any cloudformation
cdk synth --hotswap
sam-beta-cdk local invoke CDKStackName/FunctionID -e events/mock.json -n envlocal.json
sam-beta-cdk local start-api -n env-local --warm-containers EAGER
cdk automatically want's docker to run the synthesis. If you don't have docker installed on your machine you will get an error.
The solution is either you install docker and start it or you can just install esbuild
npm install esbuild
because it's the default thing. It will resolve your error on the pipeline
