Template is not loaded

I’m updating my app to use Webpack 2. While ngtable is working fine if loaded with webpack 1, I experience an issue while loading with webpack 2.

The browser console shows GET http://app.finderbox.dev/app/ng-table/pager.html 404 (Not Found). In the component loading the table I set some log output:

$templateCache.get('http://app.finderbox.dev/app/ng-table/pager.html'):  undefined
$templateCache.get('http://app.finderbox.dev/ng-table/pager.html'):  undefined
$templateCache.get('ng-table/pager.html'):  Promise {$$state: Object}

It seems to be that ngtable loads templates with a different ID. @TheLarkInn: do you think that it could be an error on the webpack side? @faceleg: is that related to your issue https://github.com/esvit/ng-table/issues/957?

I had the same issues with some missing html templates when using ngTable with Webpack 2.2. Importing the ngTable module from the /bundles directory seems to be working properly. But this is more like a workaround for now I guess.

import { ngTableModule } from 'ng-table/bundles/ng-table';

angular.module('myapp', [
    ngTableModule.name
]);

I managed to get the templates loading without any manual steps, by configuring Webpack with the following in my webpack.config.js file (using Webpack 3.11.0):

    module: {
      rules: [
        // ...
        { test: /ng-table\/.*\.html$/, use: ['ngtemplate-loader?requireAngular&relativeTo=/src/browser/&prefix=ng-table/', 'html-loader'] }
      ]
    }

This also requires the ngtemplate-loader and html-loader NPM packages to be installed; once that is done, this config should work as-is for anyone else using Webpack 3.x. (For Webpack 2.x or 4.x, a similar line should work but maybe in a different part of the Webpack config file). This causes Webpack to compile the templates into my vendor.bundle.js file as follows:

/* 570 */
/***/ (function(module, exports, __webpack_require__) {

// Module
var code = "<div class=\"ng-cloak ng-table-pager\" ng-if=\"params.data.length\"> <div ng-if=\"params.settings().counts.length\" class=\"ng-table-counts btn-group pull-right\"> <button ng-repeat=\"count in params.settings().counts\" type=\"button\" ng-class=\"{'active':params.count() == count}\" ng-click=\"params.count(count)\" class=\"btn btn-default\"> <span ng-bind=\"count\"></span> </button> </div> <ul ng-if=\"pages.length\" class=\"pagination ng-table-pagination\"> <li class=\"page-item\" ng-class=\"{'disabled': !page.active && !page.current, 'active': page.current}\" ng-repeat=\"page in pages\" ng-switch=\"page.type\"> <a class=\"page-link\" ng-switch-when=\"prev\" ng-click=\"params.page(page.number)\" href=\"\">&laquo;</a> <a class=\"page-link\" ng-switch-when=\"first\" ng-click=\"params.page(page.number)\" href=\"\"><span ng-bind=\"page.number\"></span></a> <a class=\"page-link\" ng-switch-when=\"page\" ng-click=\"params.page(page.number)\" href=\"\"><span ng-bind=\"page.number\"></span></a> <a class=\"page-link\" ng-switch-when=\"more\" ng-click=\"params.page(page.number)\" href=\"\">&#8230;</a> <a class=\"page-link\" ng-switch-when=\"last\" ng-click=\"params.page(page.number)\" href=\"\"><span ng-bind=\"page.number\"></span></a> <a class=\"page-link\" ng-switch-when=\"next\" ng-click=\"params.page(page.number)\" href=\"\">&raquo;</a> </li> </ul> </div> ";
// Exports
var _module_exports = code;;
var path = 'ng-table/pager.html';
var angular = __webpack_require__(0);
angular.module('ng').run(['$templateCache', function(c) { c.put(path, _module_exports) }]);
module.exports = path;

/***/ }),

Note how the path is ng-table/pager.html. The relativeTo=/src/browser/ part of the Webpack config turns node_modules/ng_table/src/browser/pager.html into pager.html, and then prefix=ng-table/ adds the ng-table prefix to the name that ngtemplate-loader compiles it with. This results in Angular’s template cache being pre-loaded with an ng-table/pager.html template, and so when the ng-table code requests the ng-table/pager.html template, Angular finds it and displays it correctly.
