Vue Class Transformer is a Nodejs CLI that transform your Vanilla Vue.js components to Typescript class based components,
following the syntax provided by the awesome vue-property-decorator library.

The Typescript transformation supposes you will use the library vue-property-decorator (or its nuxt variant nuxt-property-decorator).
You should only select .vue files.
It will work even if your SFC imports an external script like so: <script src="./index.js" />
# Transform a single component
vct ./components/index.vue
# Select all .vue files under the components/ folder (deep search).
vct ./components/**/*.vue| Name | Alias | Default value | Description |
|---|---|---|---|
| version | Print the cli version. | ||
| nuxt | -n | false | Import the class properties from nuxt-property-decorators instead of vue-property-decorators |
| force | -f | false | Transform the script in place, do not create a new file |
| output | -o | ./generated | Specify the transformed components output folder |
| verbose | -v | false | Trigger verbose mode. Display script details. |
| order | "data props computed watcher hooks methods other" | Specify the order of the component properties on the transformed script. Currently, if you omit one of the section, it won't be present on the converted component script. |
# Use the nuxt library and write the transformed components in a new transformed/ folder.
vct -n -o ./components/transformed/ ./components/*.vue
# Write the transformed components in the existing files
# and specify the order of the class properties.
# Do not forget to use the -- at the end to separate the order parameters and the files glob argument.
vct -f --order data hooks watcher computed methods other -- components/*.vue- !!! Add more unit tests (edge cases, normal cases, typescript vanilla syntax etc.)
- !! Keep directory tree for output files (don't create everything under generated/ or same name files will override themselves)
