Today I learned

You can throw errors in Express and handle them correctly.

In this gist I put an example of how you can use it with Zod to customize the ZodError to a readable error message.

Before Express V5 you had to use express-async-errors, but now you can do this automatically.

You can pass --experimental-strip-types to enable Node.js to run TS files:

node --experimental-strip-types

• Use --watch flag to run on watch mode (no need for nodemon anymore!)
• Use --env-file=.env to handle the dotenv file

I once struggled with updating the updatedAt date of the post on my previous attempts to blog.

simple-git enables me to do this and many other cool stuff with git.

For example, on /now page the updated time can be fetched by passing the file:

const git = simpleGit();
let lastCommit: GitLogCommit | null = null;
const file = path.join(process.cwd(), 'src', 'pages', 'now.astro');
 
try {
  const log = await git.log({ file });
  lastCommit = log.latest;
} catch (err) {
  console.error(err);
}

Then just format it with dayjs:

dayjs(lastCommit?.date).format('YYYY-MM-DD HH:mm');
