Frequently Asked Questions

Semo is a bit slow, how can I optimize it?

Compared to some scripts with simpler and more straightforward logic, Semo considers many flexibility settings, including but not limited to multi-layer scanning of plugins, configuration override rules, hook mechanisms, etc. Among these, the biggest impact comes from the I/O burden of plugin scanning. Some optimizations have already shown some effect.

Furthermore, up to now, the focus has been on exploring the various possibilities of Semo in business development. Performance issues haven't been a major concern yet, so the priority has been on exploring and accommodating various possibilities.

Speed can be further increased by narrowing the plugin scan scope:

semo status --disable-global-plugin --disable-home-plugin

If you don't want to type this every time, you can put it in the .semorc.yml file:

--disable-global-plugin: true
--disable-home-plugin: true

or

disableGlobalPlugin: true
disableHomePlugin: true

Can Semo directly run Typescript commands?

Simply put, no. If it could, wouldn't it become Deno? However, under specific conditions, it is possible. Here are the steps:

1. Your project should have the typescript and tsx packages

ts-node could also be an option here, but testing showed tsx has better compatibility.

pnpm add typescript tsx -D

2. Initialize tsconfig.json

npx tsc --init

You can configure it as needed, but the minimum required change is:

"target": "es6",

The reason is that the transformed code contains async/await.

3. Configure a scripts command in package.json

"scripts": {
    "semo": "tsx ./node_modules/@semo/cli/lib/bin.js"
}

4. Modify .semorc.yml

Add support for typescript:

typescript: true

5. Finally, create a TypeScript command-line script

semo g command test
pnpm semo test

Lastly, this method is more suitable for defining local commands. Performance is slower than executing compiled code, but the development experience is better. We can even choose not to build the Semo code at all and only execute it locally under tsx.
