# Fluent Bit / wasi_serde_json
This source source tree provides an example of WASM program with WASI mode.
## Prerequisites
* Rust
* rustc 1.61.0 (fe5b13d68 2022-05-18)
* [rustup](https://rustup.rs/) (For preparing rust compiler and toolchains)
## How to build
Add `wasm32-wasi` target for Rust toolchain:
```console
$ rustup target add wasm32-wasi
```
Then, execute _cargo build_ as follows:
```console
$ cargo build --target wasm32-wasi --release
```
Finally, under target/wasm32-wasi/release directory, `*.wasm` file will be created:
```console
$ ls target/wasm32-wasi/release/*.wasm
target/wasm32-wasi/release/wasi_serde_json.wasm
```
## How to confirm WASI integration
Create parsers.conf as follows:
```ini
[PARSER]
Name wasi
Format json
Time_Key time
Time_Format %Y-%m-%dT%H:%M:%S.%L %z
```
And Create fluent-bit configuration file as follows:
```ini
[SERVICE]
Flush 1
Daemon Off
Parsers_File parsers.conf
Log_Level info
HTTP_Server Off
HTTP_Listen 0.0.0.0
HTTP_Port 2020
[INPUT]
Name exec_wasi
Tag exec.wasi.local
WASI_Path /path/to/wasi_serde_json.wasm
Parser wasi
[OUTPUT]
Name stdout
Match *
```
