Performance Improvements
BREAKING CHANGES
In order to speed up the build and reduce the main bundle size, we have moved the ionicons outside the webpack build pipeline.
Instead, a new copy task needs to be added to the angular.json, specifically to the the "assets" option of the "build".
angular.json
{
"projects": {
"app": {
"architect": {
"build": {
"options": {
"assets": [
{
"glob": "**/*",
"input": "src/assets",
"output": "assets"
},
+ {
+ "glob": "**/*.svg",
+ "input": "node_modules/ionicons/dist/ionicons/svg",
+ "output": "./svg"
+ }
