jsreact - GET http://localhost:8080/manifest.json 404 (Not Found)
The problem is not only with manifest.json but with all json files. As it says here: https://stackoverflow.com/a/29633038/3231884 , you need to setup the web.config according to the following example:
<?xml version="1.0"?><configuration> <system.webServer> <staticContent> <remove fileExtension=".json" /> <mimeMap fileExtension=".json" mimeType="application/json" /> </staticContent> </system.webServer></configuration> Afterwards, you should make 'npm run build' copy it to the build folder by following these steps (credits to Liviu Costea):https://medium.com/hackernoon/adding-web-config-to-react-projects-3eb762dbe01f
