TypeError: isbot_1.default is not a function

[massa-man]

TS Type Definitions appear to have issues. When upgrading to the latest version, I start getting the following error:

TypeError: isbot_1.default is not a function

After upgrading to 2.4.0, the old way of importing the library in TS started throwing errors in the TS compiler:

import * as isBot from 'isbot';

Now generates the following error:

Cannot invoke an expression whose type lacks a call signature. Type 'typeof import("node_modules/isbot/index")' has no compatible call signatures.ts(2349)

To remove the TS compiler error, I had to change the import to:

import isBot from 'isbot';

But this now throws a runtime error (compilation works OK), as follows:

TypeError: isbot_1.default is not a function

I can see that the main change from the previous version I was using (v2.1.2) is the addition of the type defs (.d.ts) file in the package.

I have done some research, and this kind of error usually is linked to invalid TS definition files. Some similar issues found on the web, with packages having similar problems:

microsoft/TypeScript#7554
iamkun/dayjs#475

My current tsconfig.json file is:

  "compilerOptions": {
    "target": "es2016",
    "module": "commonjs",
    "strict": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "sourceMap": true,
    "types": ["node", "aws-lambda"]
  }
}

And environment:

isbot: 2.4.0
node: 10
typescript: 3.5.2
