This is an application that translates text entered in Japanese into English and tweets it, defined using AWS CDK v2 (golang) and using AWS Step Functions to connect the translation and tweeting processes.
# Preparation
1. Check your AWS CDK version.
```bash
cdk --version
```
If you have not installed it, please use the following command to install it.
```bash
npm install -g aws-cdk
```
This application is intended for use with AWS CDK `v2.0.0` or higher.
2. Getting Twitter API's some tokens.
⚠️ You will need the Twitter API key and secret, as well as the access token and access token secret. Please create an app on the Twitter Developer page and obtain each token.
1. Create `.env` file.
```bash
cp .env.sample .env
```
And, replace values of each environment variables.
2. Load environment variables.
```bash
source .env
```
# Build
1. Build Tweet Lambda Function
```bash
cd resources/lambda_functions/tweet \
&& GOARCH=amd64 GOOS=linux go build -o bin/main
```
# Deploying
1. bootstrap
```bash
cdk bootstrap
```
1. Build Lambda functions
```bash
make build-tweet
```
1. Load environment values
```bash
source .env
```
1. Generate CFn template
```bash
cdk synth
```
1. deploy
```bash
cdk deploy
```
# Testing
```bash
go test .
```
# Manual execution
Execute Lambda functions and Step Functions state machine manually by using AWS CLI.. (The latest versions at the time of this writing are `v2.4.4` and `1.22.18`.)
## Tweet Lambda Function
```bash
aws lambda invoke \
--function-name honyakutter-go-tweet-function \
--invocation-type Event \
--region ap-northeast-1 \
--payload fileb://testdata/tweet_lambda_payload.json \
out
```
## Start state machine
1. Get state machine ARN
```bash
STATEMACHINE_ARN=$(
aws stepfunctions list-state-machines \
--query "stateMachines[?name=='honyakutter-go-translate-tweet-state-machine'].stateMachineArn" \
--output text
) && echo "${STATEMACHINE_ARN}"
```
2. execute
```bash
aws stepfunctions start-execution \
--state-machine-arn "${STATEMACHINE_ARN}" \
--input file://testdata/statemachine_input.json
```
