Description

Hey,

when generating a parameter with the format 'date', it is falsely converted to 'date-time'. So in my case 'dateFrom' contains a time (e.g. '2019-12-10T17:56:56.999Z'), but should look like this: '2019-12-10'.

openapi-generator version

4.2.2

OpenAPI declaration file content or url

...
- name: date_from
          in: query
          description: >-
            Date parameter to search for ... (format\: \"yyyy-MM-dd\")
          required: false
          schema:
            type: string
            format: date
...

Command line used for generation

openapi-generator generate -i assets/api.yaml -g typescript-rxjs -o src/lib

Steps to reproduce

• Generate the api
• View the dateFrom parameter

Suggest a fix

As in the typescript-fetch generator, write instead of .toISOString():

.toISOString().substr(0,10) or
.toISOString().split('T')[0]

@denyo could you take a look at this issue? This seems to be easy fixable. I'd appreciate it a lot!

[macjohnny]

@guidoknoll would you like to implement a fix?

[guidoknoll]

Yeah, i could do that too. But I've never committed to an open source project like this before but I'll try!

[macjohnny]

as a starting point:
adjust the template in https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator/src/main/resources/typescript-rxjs/apis.mustache
then run mvn clean package
and re-generate the samples by running https://github.com/OpenAPITools/openapi-generator/blob/master/bin/typescript-rxjs-petstore-all.sh

finally commit the changed templates and the generated samples.

@guidoknoll you can take the package from my forks, there this and some other problems are fixed https://github.com/Xambey/openapi-generator-cli and https://github.com/Xambey/openapi-generator
openapi-generator-cli.zip

The fix was quite easy and no samples changed. @macjohnny to which branch should i commit my changes or can i create my own?

[macjohnny]

You can fork the repo, create your own branch and then file a PR
