# Using deno
|
||||
|
||||
You can build the example with
|
||||
|
||||
```sh
|
||||
$ ./build.sh
|
||||
```
|
||||
|
||||
and test it with
|
||||
|
||||
```sh
|
||||
$ deno run --allow-read test.ts
|
||||
```
|
||||
|
||||
The `--allow-read` flag is needed because the wasm file is read during runtime.
|
||||
This will be fixed when https://github.com/denoland/deno/issues/5609 is resolved.
