I was trying to run webpack-4 first time
webpack ./src/js/app.js ./dist/app.bundle.js
it shows warning / error :
WARNING in configuration
The 'mode' option has not been set, webpack will fallback to 'production' for this value. Set 'mode' option to 'development' or 'production' to enable defaults for each environment.
You can also set it to 'none' to disable any default behavior. Learn more: https://webpack.js.org/concepts/mode/
ERROR in multi ./src/js/app.js ./dist/app.bundle.js
Module not found: Error: Can't resolve './dist/app.bundle.js' in 'D:\wamp64\www\webpack-4'
@ multi ./src/js/app.js ./dist/app.bundle.js
Then i tried to change the mode
webpack --mode development
it shows :
ERROR in Entry module not found: Error: Can't resolve './src'
Resolved
Spent a lot of time to find out the solution.
Solution: Add index.js
file into src
folder.
That's it!.. solved :)
During Research, I found some facts about webpack 4 :
webpack 4 doesn’t need a configuration file by default!
webpack 4 there is no need to define the entry point: it will take ./src/index.js
as the default!
