Develop a TypeScript class in a distinct file

I currently have ag-grid implemented in an Angular project with a CustomFilter. The problem is that the file containing the code for the CustomFilter function is becoming quite large and difficult to manage. I am now looking to move the CustomFilter to a separate file for better organization.

Below is a snippet of my code showing the column definition in Angular using TypeScript:

 "colId": column.FieldName,
 "width": column.Width,
 "filter": CustomFilter,

The code for the CustomFilter function resides in the same file, outside of the class where the column definition is located:

function CustomFilter() {
}

CustomFilter.prototype.setGuiTemplate = function (params) {

}
...

I am aiming to relocate the CustomFilter to a separate file and then import it into the main file for a cleaner structure.

Answer №1

If you want to create a custom filter, simply create a ts file and export your function like the example below:

export function CustomFilter(params) {
    // Add your code here
}

Then, you can easily import the function in your code (your IDE will provide suggestions for importing).
