Options for transforming a JavaScript or TypeScript file.

@see {@link transform}

Fields

lang: Option<String>

Treat the source text as js, jsx, ts, tsx, or dts.

source_type: Option<String>

Treat the source text as script or module code.

cwd: Option<String>

The current working directory. Used to resolve relative paths in other options.

sourcemap: Option<bool>

Enable source map generation.

When true, the sourceMap field of transform result objects will be populated.

@default false

@see {@link SourceMap}

assumptions: Option<CompilerAssumptions>

Set assumptions in order to produce smaller output.

typescript: Option<TypeScriptOptions>

Configure how TypeScript is transformed.

jsx: Option<Either<String, JsxOptions>>

Configure how TSX and JSX are transformed.

target: Option<Either<String, Vec<String>>>

Sets the target environment for the generated JavaScript.

The lowest target is es2015.

Example:

• 'es2015'
• ['es2020', 'chrome58', 'edge16', 'firefox57', 'node12', 'safari11']

@default esnext (No transformation)

@see esbuild#target

helpers: Option<Helpers>

Behaviour for runtime helpers.

define: Option<FxHashMap<String, String>>

Define Plugin

inject: Option<FxHashMap<String, Either<String, Vec<String>>>>

Inject Plugin

decorator: Option<DecoratorOptions>

Decorator plugin

plugins: Option<PluginsOptions>

Third-party plugins to use.
