Wails: warning: webkit_javascript_result_get_global_context and webkit_javascript_result_get_value are deprecated
Description
When compiling Go applications using Wails with go get/go build/go install, a set of warnings are printed to the terminal. These warnings are mainly due to the use of two deprecated functions of Webkit, namely webkit_javascript_result_get_global_context and webkit_javascript_result_get_value.
This is mostly apparent when using go install ./... to build all Go packages and commands of a given repository, as otherwise one would use wails build (which seems to silent these warnings).
For at least one of the deprecated functions (webkit_javascript_result_get_value), a replacement function is suggested (webkit_javascript_result_get_js_value).
‘webkit_javascript_result_get_value’ is deprecated: Use 'webkit_javascript_result_get_js_value' instead
No replacement function is listed for webkit_javascript_result_get_global_context’.
warning: ‘webkit_javascript_result_get_global_context’ is deprecated
To Reproduce
Steps to reproduce the behaviour:
- Run
wails initto create a new project, and select any of the templates (I tried Angular, but all should illustrate the same warning). - Navigate into the newly created directory and run
go install
Expected behaviour
Successful build with no warning messages.
Observed behaviour
Successful build but with warning messages.

Hi. This is a known issue and will be addressed once we move from WebView.
Use wails build for compilation.
