Ruby가 Amplify를 즐길 수 있을까요?
개시하다
최근에 웹 애플리케이션을 설치하기 위해 Amplify를 만졌습니다.후면 깔끔하게 만들려고 할 때 좋긴 하죠.
저는 개인적으로 뭐가 좋을까요?
APIGW>Cognito>Lambda>DynamoDB 앱으로 제작에 일반적으로 필요한 물건을 모두 덩굴을 타고 참외를 만지는 식으로 하고 Lambda에서 NodeJS를 선택하면 다이나모DB와 APIGW를 통해 CRUD 함수를 자동으로 생성할 수 있다.어?루피는?
다만, 루비이스트의 저로서는 앰플리프 CLI에서 루비를 선택하지 못하면 동력이 떨어진다.
amplify function add 이걸 보는 순간 .NET에게 지다니!한층 더 움푹 들어가다.(Amplify 버전은 4.45.2)? Choose the runtime that you want to use: (Use arrow keys)
.NET Core 3.1
Go
Java
❯ NodeJS
Python
Ruby 를 사용해 보십시오.
그럼 루비를 사용해 보세요.Amplify가 Ruby를 지원하지 않는 이상 Amplify가 눈치채지 못하도록 Ruby를 사용할 수밖에 없다.우선 운행시간
Node인 척하고 루비로 대체하는 작전이다.amplify init
인터넷 애플리케이션이라 이런 느낌
init이다.$ amplify init
Note: It is recommended to run this command from the root of your app directory
? Enter a name for the project todo
? Enter a name for the environment dev
? Choose your default editor: Visual Studio Code
? Choose the type of app that you're building javascript
Please tell us about your project
? What javascript framework are you using none
? Source Directory Path: src
? Distribution Directory Path: dist
? Build Command: npm run-script build
? Start Command: npm run-script start
Using default provider awscloudformation
? Select the authentication method you want to use: AWS profile
For more information on AWS Profiles, see:
https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html
? Please choose the profile you want to use default
amplify api add
API부터 제작합니다.여기서부터 덩굴을 타고 참외를 만지는 식으로 다이나모DB까지 제작됐다.이곳의 점심시간은 사용하는 척
Node.$ amplify api add
? Please select from one of the below mentioned services: REST
? Provide a friendly name for your resource to be used as a label for this category in the project: todoAPI
? Provide a path (e.g., /book/{isbn}): /tasks
? Choose a Lambda source Create a new Lambda function
? Provide an AWS Lambda function name: todoFunc
? Choose the runtime that you want to use: NodeJS
? Choose the function template that you want to use: CRUD function for DynamoDB (Integration with API Gateway)
? Choose a DynamoDB data source option Create a new DynamoDB table
Welcome to the NoSQL DynamoDB database wizard
This wizard asks you a series of questions to help determine how to set up your NoSQL database table.
? Please provide a friendly name for your resource that will be used to label this category in the project: todoDB
? Please provide table name: todoTable
You can now add columns to the table.
? What would you like to name this column: task-id
? Please choose the data type: string
? Would you like to add another column? No
Before you create the database, you must specify how items in your table are uniquely organized. You do this by specifying a primary key. The primary key uniquely identifies each item in the table so that no two items can have the same key. This can be an individual column, or a combination that includes a primary key and a sort key.
To learn more about primary keys, see:
https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.CoreComponents.html#HowItWorks.CoreComponents.PrimaryKey
? Please choose partition key for the table: task-id
? Do you want to add a sort key to your table? No
You can optionally add global secondary indexes for this table. These are useful when you run queries defined in a different column than the primary key.
To learn more about indexes, see:
https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.CoreComponents.html#HowItWorks.CoreComponents.SecondaryIndexes
? Do you want to add global secondary indexes to your table? No
? Do you want to add a Lambda Trigger for your Table? No
Successfully added DynamoDb table locally
Available advanced settings:
- Resource access permissions
- Scheduled recurring invocation
- Lambda layers configuration
? Do you want to configure advanced settings? No
? Do you want to edit the local lambda function now? No
Successfully added resource todoFunc locally.
Next steps:
Check out sample function code generated in <project-dir>/amplify/backend/function/todoFunc/src
"amplify function build" builds all of your functions currently in the project
"amplify mock function <functionName>" runs your function locally
"amplify push" builds all of your local backend resources and provisions them in the cloud
"amplify publish" builds all of your local backend and front-end resources (if you added hosting category) and provisions them in the cloud
Succesfully added the Lambda function locally
? Restrict API access No
? Do you want to add another path? No
Successfully added resource todoAPI locally
Some next steps:
"amplify push" will build all your local backend resources and provision it in the cloud
"amplify publish" will build all your local backend and frontend resources (if you have hosting category added) and provision it in the cloud
? Choose the runtime that you want to use: NodeJS
? Choose the function template that you want to use: CRUD function for DynamoDB (Integration with API Gateway)
? Restrict API access No
amplify push
일단 여기
push에서 해볼게요.$ amplify push

런타임을 루비로 바꾸기
그럼 여기서 몰래 런타임과 프로세서를 루비로 바꾸세요.Amplify가 눈치채지 못하도록 빠르게 진행합니다.

어떻게
이렇게 되면 펀션은 앰플리파이 관리에서 벗어나 앞으로 펀션은 앰플리파이로 접촉하지 않고 별도로 관리할 수 있게 된다.

그럼 이쯤 되면 앰플리파이가 의미가 있다고 생각해요? 절반 정도면 루비를 할 수 있을 것 같아요.

다른 한편, 각 설정은 대략적이고 세부 부분은
amplify 이외에 개별적으로 설정해야 한다.[1] Reference
