Getting error "An identifier or keyword cannot immediately follow a numeric literal" on api routes containing numbers (api/1/endpoint)

[samzmann]

Some of my API routes look like this: /api/3/ContainerHistory/GetUserContainers This leads to the following error when generating types:

SyntaxError: An identifier or keyword cannot immediately follow a numeric literal. (1740:2)

This is the command I'm using to run the script:

yarn swagger-typescript-api -p https://xxx.json -o ./src/helpers/ -n apiGenerated.ts"

After examining the swagger-typescript-api options, I don't see anything that would fix this. Any idea how to resolve this?

@vvitto I also have similar issue with operationId, I had to resolve this issue by removing operationId started with number, like operationId: 2ndChance I think it's because JavaScript cannot make method starting with number and this library also doesn't know how to deal with those cases.

[dkocich]

we have a similar issue, I guess that some backend libs (in my case swagger-php https://github.com/zircote/swagger-php/blob/master/src/Processors/OperationId.php) might generate "operationId": e.g. "e42e57b0ba92f23833e2cb4ebff10a3c" to add unique ID to each version of endpoint+method... Then sometimes it starts with a number and this ends in a similar error while regenerating TS code from API doc - number can't be used to start name of TS const
