The Digital Garden plugin is fantastic. It's free and open source, and the service it depends on, Vercel, has a free version.
However, the free version of Vercel has a limit on the number of deployments, which is 100 per day. We may run out of the quota if we want to tune some details.
Thankfully, the plugin's author provided a local deployment method that works well.
I just put some details in here for documentation.
Full discussion: Local deployment · oleeskild/obsidian-digital-garden · Discussion (github.com)

1. Clone the digital garden repo (we might have done this before if we've already modified the custom-style.scss or other files to customize our garden)
2. In terminal, cd to the repo folder, type npm install express --save

> cd <path to the repo>
> npm install express --save

3. On the same place, add a new file app.js with the following content:

const express = require('express')
const app = express()
const port = 8080; 

app.use(express.static('dist'))

app.get('*', (req, res)=>{
  res.redirect("/404")
})

app.listen(port, () => {
  console.log(`Digital garden running on port ${port}`)
})   

4. On terminal, execute the following:

> npm install
> npm run build
> node app.js

5. On the browser, type localhost:8080, our garden should appear

After we made some changes, to see the new contents, first type ctrl + c to interrupt the current one, then type npm run build and node app.js again.
