DevTools in release mode

[rdwnsjjd]

How to enable dev tools (inspect) in the final built (released) app?
I used yarn tauri build --debug but still not showing inspect.

This got answered on discord. For others who are searching for this here is the answer:
There are two methods:

1. Build the whole app in debug mode (tauri build --debug). The binary will end up in target/debug! This of course is not actually in release mode, but the bundler etc. will do the same as they would in the actual release mode. The only difference is how rust compiles the binaries.
2. Build the app in release mode but wry in debug mode. The binary will end up in target/release! For this you need to add the following to your Cargo.toml file. Edit: This answer was posted for 1.0.0-beta versions, for rc and beyond see the "Edit" section at the end of this comment.

[profile.release.package.wry]
debug = true
debug-assertions = true

Edit: As of recent versions it is possible to add the "devtools" features flag to the tauri dependency in Cargo.toml to enable the dev tools in release mode without debug mode shenanigans. Note, that we of course still don't recommend that you ship your app with devtools enabled!
Example: tauri = { version = "1.0.0-rc.8", features = ["api-all", "devtools"] }

This is not working for tauri 1.0, would you kindly share any solutions used in tauri@1.0-rc

@Lantianyou You can check the "edit" section at the bottom of my message about the devtools feature flag and this comment for an example: #3059 (reply in thread).
Edit: I edited my message to include the same example.

Thank you so much about it. It is my fault I have not read your detailed explaination.

Just tried this, using the wry approach worked with cargo run but not npm run tauri build. I had to add the devtools feature flag in the Cargo.toml to get it to work with all ways of building.

I added the following to src-tauri/Cargo.toml, and run yarn tauri build -t x86_64-pc-windows-msvc, but I still could not open devtools.

[profile.release.package.wry]
debug = true
debug-assertions = true

[liudonghua123]

I can use devtools via updating the dependences from tauri = { version = "1.0.0-rc.7", features = ["api-all"] } to tauri = { version = "1.0.0-rc.7", features = ["api-all", "devtools"] } in src-tauri/Cargo.toml.
