Simple log viewer. Works with log that have json on each line. Works in both Web (WASM) and on native. Defaults are configured for bunyan formatted logs but these are setup as setting and are able to be changed (UI not implemented to change at present due to no demand). For rust programs one can use the crate tracing_bunyan_formatter to generate logs as done in the book Zero To Production In Rust.
You can use the deployed version without install at https://c-git.github.io/log-viewer/
It is expected that the file will contain multiple json objects separated by new lines. If a line is not valid json it can be converted into a Log record with the entire line being one json field. See samples. A toy example would be:
{"v":0,"name":"my_server","msg":"Server address is: 127.0.0.1:8000","level":30,"hostname":"my_computer","pid":42127,"time":"2024-02-10T03:10:25.952130465Z","target":"my_server::startup","line":34,"file":"crates/wic-server/src/startup.rs"}
{"v":0,"name":"my_server","msg":"starting 8 workers","level":30,"hostname":"my_computer","pid":42127,"time":"2024-02-10T03:10:25.952653399Z","target":"actix_server::builder","line":240,"file":"/home/user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/actix-server-2.3.0/src/builder.rs"}
{"v":0,"name":"my_server","msg":"Tokio runtime found; starting in existing Tokio runtime","level":30,"hostname":"my_computer","pid":42127,"time":"2024-02-10T03:10:25.952767514Z","target":"actix_server::server","line":197,"file":"/home/user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/actix-server-2.3.0/src/server.rs"}
We do not test on older version of rust so it is possible you may get compilation errors if you are not on the latest version of stable rust.
To get the most recent stable version use rustup update.
cargo run --release
On Linux you need to first run:
sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev libssl-dev
On Fedora Rawhide you need to run:
dnf install clang clang-devel clang-tools-extra libxkbcommon-devel pkg-config openssl-devel libxcb-devel gtk3-devel atk fontconfig-devel
You can compile your app to WASM and publish it as a web page.
We use Trunk to build for web target.
- Install the required target with
rustup target add wasm32-unknown-unknown. - Install Trunk with
cargo install --locked trunk. - Run
trunk serveto build and serve onhttp://127.0.0.1:8080. Trunk will rebuild automatically if you edit the project. - Open
http://127.0.0.1:8080/index.html#devin a browser. See the warning below.
assets/sw.jsscript will try to cache our app, and loads the cached version when it cannot connect to server allowing your app to work offline (like PWA). appending#devtoindex.htmlwill skip this caching, allowing us to load the latest builds during development.
- Just run
trunk build --release. - It will generate a
distdirectory as a "static html" website - Upload the
distdirectory to any of the numerous free hosting websites including GitHub Pages. - we already provide a workflow that auto-deploys our app to GitHub pages if you enable it.
To enable Github Pages, you need to go to Repository -> Settings -> Pages -> Source -> set to
gh-pagesbranch and/(root).If
gh-pagesis not available inSource, just create and push a branch calledgh-pagesand it should be available.
