Log Viewer

Simple log viewer. Works with log that have json on each line. Works in both Web (WASM) and on native.

You can use the deployed version without install at https://c-git.github.io/log-viewer/

Description of expected log file format

It is expected that the file will contain multiple json objects separated by new lines. 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"}

How to run

Make sure you are using the latest version of stable rust by running rustup update.

Native

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

Web Locally

You can compile your app to WASM and publish it as a web page.

We use Trunk to build for web target.

1. Install the required target with rustup target add wasm32-unknown-unknown.
2. Install Trunk with cargo install --locked trunk.
3. Run trunk serve to build and serve on http://127.0.0.1:8080. Trunk will rebuild automatically if you edit the project.
4. Open http://127.0.0.1:8080/index.html#dev in a browser. See the warning below.

assets/sw.js script 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 #dev to index.html will skip this caching, allowing us to load the latest builds during development.

Web Deploy

1. Just run trunk build --release.
2. It will generate a dist directory as a "static html" website
3. Upload the dist directory to any of the numerous free hosting websites including GitHub Pages.
4. 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-pages branch and / (root).

If gh-pages is not available in Source, just create and push a branch called gh-pages and it should be available.
