Sweetalert is not running, I got an error on it's TS file

I'm giving mainteinence to an app with Angular 7.0.7 and Node 10.20.1. I were working fine, I installed long ago Sweetalert and the plugin was working fine. Yesterday my PC restarted and when I run ng serve I got this error

ERROR in node_modules/sweetalert2/sweetalert2.d.ts(277,39): error TS1005: ',' expected. node_modules/sweetalert2/sweetalert2.d.ts(277,68): error TS1011: An element access expression should take an argument. node_modules/sweetalert2/sweetalert2.d.ts(277,69): error TS1005: ';' expected. node_modules/sweetalert2/sweetalert2.d.ts(277,70): error TS1128: Declaration or statement expected. node_modules/sweetalert2/sweetalert2.d.ts(277,82): error TS1005: '(' expected.

My package.json is this

{
  "name": "frontend",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve --proxy-config proxy.conf.json",

    "ts-node": "~7.0.0",
    "tslint": "~5.11.0",
    "typescript": "~3.1.6"
  }
}

I did a lot of tricks

I went to the sweetalert file, on the error line and I found this code

/**
     * Provide an array of SweetAlert2 parameters to show multiple popups, one popup after another.
     *
     * @param steps The steps' configuration.
     */
    function queue<T>(steps: readonly (SweetAlertOptions | string)[]): Promise<T>;

In all cases, is the same error... What is wrong?

The problem most probably comes from a mismatch on the typescript version needed by sweetalert2 and the one of your project.

On your package.json you have the following:

"sweetalert2": "^9.14.0" // Wants any version like 9.X where X must be >= 14
"typescript": "~3.1.6" // Wants any version like 3.1.Y where Y must be >= 6

Check your package-lock.json to be sure what is the sweetalert2 version that is locked by your project (if you have no lock, it will be 9.17.2). You can go then to https://github.com/sweetalert2/sweetalert2/blob/v[THE VERSION]/package.json to check the version needed by typescript.

If you see 9.14.0, they expect as well typescript version ^3.5

I have been struggling with it as well.

With these package versions it works for me.

"dependencies": {
  // ... 
  "@angular/common": "^7.2.16",
  "@angular/core": "^7.2.16",
  // ...
  "sweetalert2": "8.19.0",
  "@sweetalert2/ngx-sweetalert2": "^6.0.0",
},
"devDependencies": {
   "typescript": "3.2.4"
}

Or try with these versions:

"sweetalert2": "^8.0.0",
"@sweetalert2/ngx-sweetalert2": "^5.0.0"

try importing using CommonJS in the component like this:

const Swal = require('sweetalert2');

worked for me ;)

Good, you just have to remove the 'readonly' and the application will work
