quasar-json-api

Description

The quasar-json-api is a library to normalize and validate your JSON Api for a Quasar Component, Directive, or Mixin.

As well, it'll create Vetur compliant files, so that when using vscode with vetur you get suggestions and completions.

(New v1.2.0): Not only that, but quasar-json-api can generate your typescript definitions automatically inferred by your JSON API. More on this below.

The output of the results will be placed in the dist/api, dist/vetur and dist/types folders, respectively.

Note: starting with v1.2.0 you no longer have to add the code to create the specific folders in ./build/index.js. If you have this, then you can safely remove it.

Usage

Before proceeding, make sure you are using the Quasar build system from the UI kit.

$ yarn add --dev quasar-json-api

In your build folder, create a file called: build.api.js

Add the following to it:

const path = require('path')
global.rootDir = path.resolve(__dirname, '..')
global.distDir = path.resolve(__dirname, '../dist')

require('quasar-json-api')({
  buildVetur: true,
  buildTypes: true
})

Notice the options? This is where you can turn on/off particular builds. By default, buildVetur is true for backwards compatibility. However, by default, the buildTypes is false and must be explicitly turned on.

In your build/script.javascript.js find the build(builds) command and modify as follows:

build(builds)
  .then(() => {
    require('./build.api.js')
  })

In your package.json, add the following for Vetur:

  "vetur": {
    "tags": "dist/vetur/tags.json",
    "attributes": "dist/vetur/attributes.json"
  },

In your package.json, add the following for Types:

  "typings": "dist/types/index.d.ts",
  },

That's it!

When you build your Component or Directive via yarn build (from your UI kit templated package), your JSON API will be Normalized and Validated and the output will be placed in the dist/api folder.

One more item to disclose. The JSON file should have the same name as your component so it can validate against the source after the normalization is done.

For instance, if your component or directive is MyComponent.js, then your JSON API file will be called MyComponent.json.

If you want to set up a script in your package.json, you can add the following:

  "scripts": {
    "build:api": "node build/build.api.js"
  },

Now, you can concentrate on any JSON API issues you have by running yarn build:api.

JSON API

Look in the library folder.

Normalization

Normalization is a check of your JSON file so that it contains all requirements.

Some properties are required based on the type.

You will see an error like this if you are missing a required property:

[Error] build.api.js: src/components/MyComponent.json ->  "props"/"items" missing required API prop "category" for its type (Array)

In this case, the JSON API item needs category: ""

Here is another common error:

[Error] build.api.js: src/components/MyComponent.json ->  "props"/"error-color" missing required API prop "examples" for its type (String)

In this case, the JSON API item needs examples: []

Validation

Validation is done after the JSON file is processed.

The code will check your declared props against the associated source file. If the definition of a prop is not in the json file, you will see a message like this:

[Error] MyComponent.json: missing "props" -> "some-prop" definition

This means, your code has, in props, a property of some-prop that is missing from your JSON API and it should be documented.

Another validation error you might see is:

[Error] MyComponent.json: missing "methods" -> "renderComponent" definition

All functions are validated against the source. Non-public functions should start with two underscores (__). All public functions should be decribed in your JSON API.
