OpenAPI generator typescript-axios changes property name, and can't pass dates as strings

Question

I'm doing code generation with the open api generator tool to generate a typescript-axios client, but unfortunately there's a couple of issues I'm running into.

1. There is a property in the open api doc we're generating from called long. However, the interface it generates changes that property to _long which is not correct. I can't find anywhere in the mustache template that is doing this so it must be happening in the CLI layer. Can this behavior be prevented?

Swagger property definition:

"long": {
  "type": "number",
  "description": "The longitude location.",
  "format": "double",
  "nullable": true
}

Codegen interface property output:

/**
 * The longitude location.
 * @type {number}
 * @memberof ...
 */
_long?: number | null;

2. Dates are passed as strings to the API and are defined as such in the open api doc, but it seems when they have a date-time format, the interface says it requires a Date object. This is not ideal in our situation, but again this appears to happen at the CLI level so I can't prevent this behavior by modifying the mustache template.

Swagger property definition:

"startDate": {
  "type": "string",
  "description": "Gets or sets the start date of the search date range.",
  "format": "date-time",
  "nullable": true
},

Codegen interface property output:

/**
 * Gets or sets the start date of the search date range.
 * @type {Date}
 * @memberof ...
 */
startDate?: Date | null;

Thanks in advance for any help!

Answer 1

You can pass a type-mappings to the CLI:

java -jar openapi-generator-4.2.3.jar generate --type-mappings DateTime=string etc..

This will turn the type Date into a string. Problem is that it doesn't matter if you define a date or a date-time in your schema definition. You will get only string now.
