Docs: Clarify that DefaultDataServiceConfig.trailingSlashEndpoints also removes leading slashes

[coder925]

Information

Current documentation for the property trailingSlashEndpoints?: boolean is:

to keep trailing slashes or not; false by default

but should be

to keep leading/trailing slashes or not; false by default

How I noticed this?

My app API is at:

• https://localhost/api

My app has different URLs for each language:

• https://localhost/ for default lanauge (English).
• https://localhost/nb for Norwegian.
• https://localhost/sv for Swedish.
  etc.

Using ngrx/data, this configuration should work for all languages:

const defaultDataServiceConfig: DefaultDataServiceConfig = {
  root: '/api'
}

but as the leading slash was removed it became relative and only the English app worked. The Norwegian app would try to find the API at https://localhost/nb/api . To fix the issue I had to add:

const defaultDataServiceConfig: DefaultDataServiceConfig = {
  root: '/api',
  trailingSlashEndpoints: true
}

I was using version 14.3.2.

Code file reference
