Leptos Axum Starter Template

This is a template for use with the Leptos web framework and the cargo-leptos tool using Axum.

Creating your template repo

If you don't have cargo-leptos installed you can install it with

cargo install cargo-leptos

Then run

cargo leptos new --git leptos-rs/start-axum

to generate a new project template.

cd {{project-name}}

to go to your newly created project. Feel free to explore the project structure, but the best place to start with your application code is in src/app.rs. Additionally, Cargo.toml may need updating as new versions of the dependencies are released, especially if things are not working after a cargo update.

Running your project

cargo leptos watch

Installing Additional Tools

By default, cargo-leptos uses nightly Rust, cargo-generate, and sass. If you run into any trouble, you may need to install one or more of these tools.

  1. rustup toolchain install nightly --allow-downgrade - make sure you have Rust nightly
  2. rustup target add wasm32-unknown-unknown - add the ability to compile Rust to WebAssembly
  3. cargo install cargo-generate - install cargo-generate binary (should be installed automatically in future)
  4. npm install -g sass - install dart-sass (should be optional in future

Compiling for Release

cargo leptos build --release

Will generate your server binary in target/server/release and your site package in target/site

Testing Your Project

cargo leptos end-to-end
cargo leptos end-to-end --release

Cargo-leptos uses Playwright as the end-to-end test tool. Tests are located in end2end/tests directory.

Executing a Server on a Remote Machine Without the Toolchain

After running a cargo leptos build --release the minimum files needed are:

  1. The server binary located in target/server/release
  2. The site directory and all files within located in target/site

Copy these files to your remote server. The directory structure should be:

{{project-name}}
site/

Set the following environment variables (updating for your project as needed):

LEPTOS_OUTPUT_NAME="{{project-name}}"
LEPTOS_SITE_ROOT="site"
LEPTOS_SITE_PKG_DIR="pkg"
LEPTOS_SITE_ADDR="127.0.0.1:3000"
LEPTOS_RELOAD_PORT="3001"

Finally, run the server binary.

leptos-tutorial's Issues

`create_resource` error expected a `std::ops::Fn<()>`

Error as of tag leptos tut(lesson): 6.1 Async - Loading Data with Resources in this repo.

I'm working through the Leptos Book/Tutorial and I've hit a wall at section 6.1 Loading Data with Resources.

I have copied the Source and Cargo.toml from CodeSandbox.

This code works as expected on CodeSandbox but I'm getting a compile error on my local machine.

The full error is:
6 1-error

And the related source:
6 1-source

I have tried the CodeSandbox Source form the next two entries (6.2 Suspense, 6.3 Transition) all work as expected on CodeSandbox, but fail with similar errors relating to create_resource on my machine.

I have noted the compiler help:

    = help: the trait `std::ops::Fn<()>` is not implemented for `ReadSignal<{integer}>`
    = note: wrap the `ReadSignal<{integer}>` in a closure with no arguments: `|| { /* code */ }`
note: required by a bound in `leptos::create_resource`

and fiddled around trying to implement its suggestion to no avail. But I really don't know enough about rust or leptos at this point to make sense of all this. I'm pretty much just guessing.


My environment:

rustc -V: rustc 1.73.0-nightly (474709a9a 2023-08-03)

trunk -V: trunk 0.17.2

macOS: Monterey 12.6.7

Cargo.toml:

[package]
name = "app"
version = "0.1.0"
edition = "2021"

[dependencies]
leptos = { git = "https://github.com/leptos-rs/leptos" }
console_log = "0.2"
log = "0.4"
console_error_panic_hook = "0.1.7"
gloo-timers = { version = "0.2", features = ["futures"] }

I tried rolling back to rust v 1.69 and leptos 0.4.0 and still got the same result.

Any suggestions, hints or guess are much appreciated!
