sort-by.pipe.ts

/*
 *ngFor="let c of oneDimArray | sortBy:'asc'"
 *ngFor="let c of arrayOfObjects | sortBy:'asc':'propertyName'"
*/
import { Pipe, PipeTransform } from '@angular/core';
import { orderBy } from 'lodash';

@Pipe({ name: 'sortBy' })
export class SortByPipe implements PipeTransform {

  transform(value: any[], order = '', column: string = ''): any[] {
    if (!value || order === '' || !order) { return value; } // no array
    if (value.length <= 1) { return value; } // array with only one item
    if (!column || column === '') { 
      if(order==='asc'){return value.sort()}
      else{return value.sort().reverse();}
    } // sort 1d array
    return orderBy(value, [column], [order]);
  }
}

There is a mistake in code. Symbol "_" not found. Need to be like this:

import { sortBy, orderBy } from 'lodash';

.....

return orderBy(value, [column], [order]);

Thanks for the mention, had designed it way back forgot to update it to newer annotations completely

Hi - I get the following error in vscode - line 15 ... [order]. Any idea what to do?

No overload matches this call.
  The last overload gave the following error.
    Argument of type 'string[]' is not assignable to parameter of type 'Many<boolean | "asc" | "desc">'.
      Type 'string[]' is not assignable to type 'readonly (boolean | "asc" | "desc")[]'.
        Type 'string' is not assignable to type 'boolean | "asc" | "desc"'.ts(2769)
collection.d.ts(1339, 9): The last overload is declared here.

Have you referred the comment for usage, because both column and order accept only string if it is an array of objects. If it's a single dimensional array only order is required

Looks like a type issue which I have to address by myself. Lodash orderBy only accepts boolean | "asc" | "desc". Thx anyhow.

I'm getting this too !
Has this been figured out ? I can't seem to figure out why it is giving me this error.
~ Thanks

The above issue started to happen due to lodash changes, you can change the type for the argument order:any

Thank You !!!!
