This uses json-server, but with the module approach: https://github.com/typicode/json-server#module
|
|
Downside: You can't pass the json-server command line options.
|
|
Instead, can override some defaults by passing a config object to jsonServer.defaults();
|
|
You have to check the source code to set some items.
|
|
Examples:
|
|
Validation/Customization: https://github.com/typicode/json-server/issues/266
|
|
Delay: https://github.com/typicode/json-server/issues/534
|
|
ID: https://github.com/typicode/json-server/issues/613#issuecomment-325393041
|
|
Relevant source code: https://github.com/typicode/json-server/blob/master/src/cli/run.js
