Unable to locate the identifier 'TextDecoder' in TypeScript version 2.7

In the development of my Angular 6 application with TypeScript 2.7, I encountered an issue when trying to implement the TextDecoder native function. Upon running ng build --aot, I received the error: error TS2304: Cannot find name 'TextDecoder'.

If anyone has any suggestions or solutions, it would be greatly appreciated. Below are the contents of my tsconfig.json file and the dependencies listed in my package.json file.

Thank you, Bob

Answer №1

To update your output bundles to ES7, locate the src/tsconfig.app.json file and include the following code in compilerOptions:

"compilerOptions": {
    "lib": [
        "es2017",
        "dom"
    ]
}

Answer №2

TextDecoder declaration can be found exclusively in TypeScript 2.8 and later versions. To access it, you must either update your TypeScript version or manually import the necessary declarations from this source into your project.

Answer №3

Include the following code at the top of your component.ts file: Specifically for Angular 5 or earlier versions

declare var TextDecoder: any

Please help me resolve this issue in TypeScript version 2.5.x

For more information, refer to this post on typescript getting error TS2304: cannot find name ' require'

Answer №4

I stumbled upon the answer right here:

For TypeScript 2.7, it's necessary to specify 'window' as type 'any' when using TextDecoder.

const textDecoder = new (window as any).TextDecoder('utf-8');
