[Question] Using multiple presets

Hey @thymikee I appreciate this preset.

Quick question: can we use multiple presets at the same time? I can’t get it to work and I’m unsure whether it’s my config or whether it’s impossible.

I’m using ts-nameof (brilliant library that allows nameof in typescript!) and it wants this config:

"globals": {
  "ts-jest": {
    "astTransformers": ["ts-nameof"]
  }
},
preset: "ts-jest",

But that will override your preset. So I combine them:

globals: {
  "ts-jest": {
    tsConfig: "<rootDir>/tsconfig.spec.json",
    stringifyContentPathRegex: "\\.html$",
    astTransformers: [
      "ts-nameof",
      require.resolve("jest-preset-angular/InlineHtmlStripStylesTransformer"),
    ]
  }
},
preset: "jest-preset-angular",      // <-- not a problem as it wraps ts-jest

But then your preset works, and that one fails (compiler doesn’t understand nameof).

Can your preset be combined with other presets? I assume so because astTransformers is an array, but in practice it doesn’t work. I just need a pointer - where do you think the problem is 1) this preset, 2) nameof preset, or 3) ts-jest?

No that doesn’t make a difference, it actually gives the same result as what I put in the original comment.

So for anyone else with this problem, the short answer is: yes, presets can be combined, and this preset seems to work perfectly in all cases.

But this particular combination doesn’t work. Probably the problem is with ts-jest or ts-nameof.

@RaviH Sorry I don’t use this anymore 😦
