Angular 4 application on Github Pages

Question

I have a simple Angular (4) application which I want to host on Github Pages, the option to do this from Angular CLI seems removed. Is there a way to do this, if so how?

this is my package.json

{
  "name": "e-portfolio",

  "scripts": {
    "ng": "ng",
    "start": "ng serve",

    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/cli": "^1.0.6",
    "@angular/common": "^4.0.0",
    "@angular/compiler": "^4.0.0",

  },

  }
}

When trying to use ng build I get this message

As a forewarning, we are moving the CLI npm package to "@angular/cli" with the next release, which will only support Node 6.9 and greater. This package will be officially deprecated shortly after.

To disable this warning use "ng set --global warnings.packageDeprecation=false".

You have to be inside an angular-cli project in order to use the build command.

Answer 1

You can use the following package https://www.npmjs.com/package/angular-cli-ghpages

Answer 2

When using this commad ng build --prod --base-href "https://USERNAME.github.io/REPOSITORY_NAME/"

I switched out to my repository which is called ePortfolio, I typed it in as eportfolio, It seems that the letter P had to be capital for it to work.

Answer 3

The easiest way that I found is a 2 steps process. First of, you need to know that Github Pages doesn't handle well base href and so disabling the pushState and removing the base href was enough on my side to get going.

Here's the steps:

1- remove the backslash "/" from the base href in your index.html

<base href="">

2- Disable the pushState by adding the argument {useHash: true}. In my case, I have an app-routing.module.ts which I updated with following code:

@NgModule({
   imports: [RouterModule.forRoot(routes, {useHash: true})], // <-- HERE
   exports: [RouterModule],
})

Then publish to a Github Page and we're in business

EDIT

Just doing step 2 is enough for it to work {useHash: true}
