TypeError: CodeBlockWriter is not a constructor

[Saopetrik]

Hey there,

I have installed the library using the command npm install --save code-block-writer

I have created a file main.js then added the example mentioned in readme.

main.js file

const CodeBlockWriter = require("code-block-writer");

const writer = new CodeBlockWriter({
    // optional options
    newLine: "\r\n",         // default: "\n"
    indentNumberOfSpaces: 2, // default: 4
    useTabs: false,          // default: false
    useSingleQuote: true     // default: false
});

writer.write("class MyClass extends OtherClass").block(() => {
    writer.writeLine(`@MyDecorator(1, 2)`);
    writer.write(`myMethod(myParam: any)`).block(() => {
        writer.write("return this.post(").quote("myArgument").write(");");
    });
});

console.log(writer.toString());

then to run it I did node main.js

I am getting an error :

const writer = new CodeBlockWriter({
               ^

Sorry I never used JS/TS . So can you please tell me how to use it correctly.

Since you're using require and not typescript with esModuleInterop, you'll need to do:

const CodeBlockWriter = require("code-block-writer").default;
