How to escape html while saving it to db?

Question

I want to escape special characters and html while saving to database , Can i use filter to achieve that task with below code i am getting an error your module is not loaded properly, Do i need to add dependeny in app.js. New to AngularJs any help will be appreciated.

main.html

<textarea rows="2" class="form-control" id="name"
    ng-model="processDTO.processLongName"
    placeholder="Business Process Name" maxlength="1024" name="processName"
    required
    ng-bind-html="escapeHtml"
    data-tooltip-html-unsafe="<div>{{1024 - processDTO.processLongName.length}} characters left</div>"
    tooltip-trigger="{{{true: 'focus', false: 'never'}[processDTO.processLongName.length >= 0 || processDTO.processLongName.length == null ]}}"
    tooltip-placement="top" tooltip-class="bluefill">
</textarea>

filter.js

angular
  .module('riskAssessmentApp', [
    'ngSanitize'
  ])
  .filter('escapeHtml', function ($sce) {
    // Modified by Rockallite: Add $sce.trustAsHtml() to mute "Error: $sce:unsafe"

    var entityMap = {
        "&": "&",
        "<": "&lt;",
        ">": "&gt;",
        '"': '&quot;',
        "'": '&#39;',
        "/": '&#x2F;'
    };

    return function(str) {
      return $sce.trustAsHtml(String(str).replace(/[&<>"'\/]/g, function (s) {
          return entityMap[s];
      }));
    }
  });

app.js

angular.module('riskAssessmentApp', [
    'angularSpinner',
    'ngResource',
    'ui.router',
    'ngCookies',
    'bacMultiselect',
    'kendo.directives',
    'kendoMultiselectTreeview',
    'offClick',

ERROR

[$injector:nomod] Module 'riskAssessmentApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

You define riskAssessmentApp module twice.

In your filter.js don't redefine it, just attach the filter to that module:

angular.module('riskAssessmentApp')
  .filter('escapeHtml', function ($sce) {
    // Modified by Rockallite: Add $sce.trustAsHtml() to mute "Error: $sce:unsafe"
    // http://stackoverflow.com/a/32835368/2293304
    // http://stackoverflow.com/a/28537958/2293304
    // https://github.com/janl/mustache.js/blob/master/mustache.js#L82
    var entityMap = {
        "&": "&",
        "<": "&lt;",
        ">": "&gt;",
        '"': '&quot;',
        "'": '&#39;',
        "/": '&#x2F;'
    };

    return function(str) {
      return $sce.trustAsHtml(String(str).replace(/[&<>"'\/]/g, function (s) {
          return entityMap[s];
      }));
    }
  });
