Description
Describe the bug
When building TypeScript/JavaScript with aws-lambda-nodejs, the parameter (Charset.UTF8) that does not escape non-ASCII characters does not work.
Regression Issue
- Select this option if this issue appears to be a regression.
Last Known Working CDK Version
v2.85.0
Expected Behavior
If UTF8 is specified for charset, --charset=utf8 is passed to esbuild so that characters are output without escaping.
example expected output
// package/example.ts
var handler = async () => {
console.log("Japanese:日本語");
};
export {
handler
};Current Behavior
Even if UTF8 parameters are passed, escaped strings are always output.
example current output
// package/example.ts
var handler = async () => {
console.log("Japanese:\u65E5\u672C\u8A9E");
};
export {
handler
};Reproduction Steps
Restores the process of setting the deleted charset.
...this.props.banner ? [`--banner:js=${JSON.stringify(this.props.banner)}`] : [],
...this.props.footer ? [`--footer:js=${JSON.stringify(this.props.footer)}`] : [],
+ ...this.props.charset ? [`--charset=${this.props.charset}`] : [],
...this.props.mainFields ? [`--main-fields=${this.props.mainFields.join(',')}`] : [],Possible Solution
