Using Typescript: invoking static functions within a constructor

This is an illustration of my class containing the relevant methods.

class Example {
    constructor(info) {
        // calling validateInfo(info)
    }

    static validateInfo(info):void {
        // validation of info
    }

I aim to invoke validateInfo in the constructor. However, using this.validateInfo(info) isn't feasible since it's a static method.

In JavaScript, a potential solution would be:

    constructor(info) {
        this.constructor.validateInfo(info)
    }

Regrettably, attempting the same approach in TypeScript results in the subsequent error message:

error TS2339: Property 'validateInfo' does not exist on type 'Function'.

Although I grasp the nature of this error, is there a TypeScript alternative analogous to the JavaScript resolution?

Answer №1

A potential issue arises when a subclass initiates the constructor instead of utilizing the Example constructor. To address this, it is advisable to directly reference the Example constructor:

constructor(info) {
    Example.validateInfo(info)
}

Alternatively, you could also contemplate converting it into a regular method rather than a static method.
