TypeScript-based imperative way to define AWS CloudFormation templates | ||
|
||
[Read the introductory blog post](https://brightinventions.pl/blog/introducing-cloudform-tame-aws-cloudformation-templates/) | ||
|
||
## Installation | ||
|
||
`npm install --save-dev cloudform` | ||
|
||
## Usage | ||
|
||
1. Define your AWS CloudFormation template in a TypeScript file, for example `template.ts`: | ||
|
||
```typescript | ||
import cloudform, {Fn, Refs, EC2, StringParameter, ResourceTag} from "cloudform" | ||
|
||
cloudform({ | ||
Description: 'My template', | ||
Parameters: { | ||
DeployEnv: new StringParameter({ | ||
Description: 'Deploy environment name', | ||
AllowedValues: ['stage', 'production'] | ||
}) | ||
}, | ||
Mappings: { | ||
DeploymentConfig: { | ||
stage: { | ||
InstanceType: 't2.small' | ||
}, | ||
production: { | ||
InstanceType: 't2.large' | ||
} | ||
} | ||
}, | ||
Resources: { | ||
VPC: new EC2.VPC({ | ||
CidrBlock: NetworkingConfig.VPC.CIDR, | ||
EnableDnsHostnames: true, | ||
Tags: [ | ||
new ResourceTag('Application', Refs.StackName), | ||
new ResourceTag('Network', 'Public'), | ||
new ResourceTag('Name', Fn.Join('-', [Refs.StackId, 'VPC'])) | ||
] | ||
}), | ||
Instance: new EC2.Instance({ | ||
InstanceType: Fn.FindInMap('DeploymentConfig', Fn.Ref('DeployEnv'), 'InstanceType'), | ||
ImageId: 'ami-a85480c7' | ||
}).dependsOn('VPC') | ||
} | ||
}) | ||
``` | ||
|
||
See also [example/example.ts](https://github.com/bright/cloudform/blob/master/example/example.ts). | ||
|
||
2\. Run `cloudform path/to/your/template.ts` to generate the CloudFormation template as JSON. | ||
|
||
It makes sense to define it in your `npm` scripts and run within your build or deployment pipeline, for example: | ||
|
||
```json | ||
"scripts" | ||
// ... | ||
"generate-cloudformation-template": "cloudform path/to/your/template > template.aws" | ||
} | ||
``` | ||
|
||
## API | ||
|
||
The types are generated automatically from the [AWS-provided schema file](http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-resource-specification.html), so `cloudform` supports all the types available in AWS CloudFormation. | ||
|
||
The simple convention is used – all the AWS types’ namespaces are available directly as exports from the `cloudform` package. All the resources within this package are available inside. This way `EC2.VPC` object from our example translates into `AWS::EC2::VPC` type we can find in [CloudFormation documentation](http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-vpc.html). All the properties also match one-to-one, including casing. | ||
|
||
Supported namespaces are: | ||
|
||
``` | ||
ApiGateway | ||
ApplicationAutoScaling | ||
Athena | ||
AutoScaling | ||
Batch | ||
CertificateManager | ||
CloudFormation | ||
CloudFront | ||

``` | ||
|
||
All [Intrinsic Tunctions](http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/intrinsic-function-reference.html) are available within `Fn` namespace: | ||
|
||
```typescript | ||
Fn.Base64(value: Value<string>) | ||
Fn.FindInMap(mapName: Value<string>, topLevelKey: Value<string>, secondLevelKey: Value<string>) | ||
Fn.GetAtt(logicalNameOfResource: Value<string>, attributeName: Value<string>) | ||
Fn.GetAZs(region?: Value<string>) | ||
Fn.ImportValue(sharedValueToImport: Value<any>) | ||
Fn.Join(delimiter: Value<string>, values: List<any>) | ||
Fn.Select(index: Value<number>, listOfObjects: List<any>) | ||
Fn.Split(delimiter: Value<string>, sourceString: Value<string>) | ||
Fn.Sub(string: Value<string>, vars [key: string]: Value<any> }) | ||
Fn.Ref(logicalName: Value<string>) | ||
|
||
// condition functions | ||
Fn.And(condition: List<Condition>) | ||
Fn.Equals(left: any, right: any) | ||
Fn.If(conditionName: Value<string>, valueIfTrue: any, valueIfFalse: any) | ||
Fn.Not(condition: Condition) | ||
Fn.Or(condition: List<Condition>) | ||
``` | ||
|
||
All the [Pseudo Parameters](http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/pseudo-parameter-reference.html) are there, too: | ||
|
||
``` | ||
Ref.AccountId | ||
Ref.NotificationARNs | ||
Ref.NoValue | ||
Ref.Partition | ||
Ref.Region | ||
Ref.StackId | ||
Ref.StackName | ||
Ref.URLSuffix | ||
``` | ||
