# Faster rebuilds with [`cargo-plonk`](https://crates.io/crates/cargo-plonk)
|
||
|
|
|
||
|
|
This document describes how to use `cargo plonk` to speed up Deno rebuilds for
|
||
|
|
faster dev cycles.
|
||
|
|
|
||
|
|
```
|
||
|
|
cargo install cargo-plonk
|
||
|
|
```
|
||
|
|
|
||
|
|
## How it works
|
||
|
|
|
||
|
|
Plonk works by hot swapping symbols using a fresh dynamic library of the local
|
||
|
|
crates.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
First, compile Deno normally.
|
||
|
|
|
||
|
|
```
|
||
|
|
cargo build -p deno [--release]
|
||
|
|
```
|
||
|
|
|
||
|
|
Run the following command to start watching for changes in `ext/webgpu` crate
|
||
|
|
and hot swap `init_ops_and_esm` function into the previously built `deno` bin.
|
||
|
|
|
||
|
|
```
|
||
|
|
cargo plonk run \
|
||
|
|
--package deno_webgpu \
|
||
|
|
--symbol init_ops_and_esm \
|
||
|
|
--bin deno \
|
||
|
|
--watch
|
||
|
|
```
|
||
|
|
|
||
|
|
> Important:
|
||
|
|
>
|
||
|
|
> Currently, this will only works for symbols that have been "materialized" in
|
||
|
|
> their crates. Cross-crate generics will not work.
|
||
|
|
|
||
|
|
You can use `cargo plonk run` to re-run commands on changes.
|
||
|
|
|
||
|
|
```
|
||
|
|
cargo plonk run -v \
|
||
|
|
-p deno_webgpu \
|
||
|
|
-s init_ops_and_esm \
|
||
|
|
-b deno \
|
||
|
|
--watch \
|
||
|
|
-- eval "await navigator.gpu.requestAdapter()" --unstable
|
||
|
|
```
|
||
|
|
|
||
|

| profile | `cargo build` | `cargo plonk build` |
|

|
|
| --------- | ------------- | ------------------- |
|
||
|
|
| `debug` | 42 s | 0.5s |
|
||
|
|
| `release` | 5 mins 12 s | 2s |
|

|
|
## Debugging
|
||
|
|
|
||
|
|
Use the `-v`/`--verbose` flag to turn on debug info.
