Introduction

Are you struggling to get started with Drop-in, a popular framework for building web applications? You're not alone. Many developers face the same issue, where they expect a seamless, zero-config experience, but end up with a frustrating error message. In this article, we'll delve into the world of Drop-in and explore the common pitfalls that lead to this error.

Expectations vs. Reality

Expectation

When using Drop-in, you expect a hassle-free experience. You run the CLI, choose a template, install dependencies, and run the start command. Voilà! Your application should be up and running without any configuration files, not even .env files. This is the promise of a zero-config experience.

Actual

However, reality is often different. You might encounter an error message that leaves you scratching your head. In this case, the error message is:

> Unexpected unhandled error.
TypeError: Missing property db at upstream
    at Module.parse (file:~/dev/test-dropin/node_modules/.pnpm/@rocicorp+zero@0.18.2025042300/node_modules/@rocicorp/zero/out/shared/src/valita.js:132:15)

This error message is cryptic, to say the least. It doesn't provide any clear indication of what went wrong or how to fix it.

Steps to Reproduce

Environment

Before we dive into the steps to reproduce the error, let's take a look at the environment:

  • Node version: v20.14.0
  • Pnpm version: 9.15.5

Steps

  1. Run the following command to create a new Drop-in project:
pnpm dlx @drop-in/new test-dropin
  1. Navigate to the project directory:
cd test-dropin
  1. Install dependencies using Pnpm:
pnpm i
  1. Select the only available template, Local First with Zero:
pnpm start
  1. Observe the error message.

Analysis

So, what's going on here? Why is Drop-in throwing an error when you expect a zero-config experience? Let's analyze the situation:

  • The error message mentions a TypeError: Missing property db at upstream. This suggests that there's an issue with the database configuration.
  • The error occurs at valita.js:132:15. This line of code is part of the @rocicorp/zero package, which is a dependency of Drop-in.
  • The error message doesn't provide any clear indication of what went wrong or how to fix it.

Conclusion

Getting started with Drop-in can be a frustrating experience, especially when you expect a zero-config experience. However, by understanding the common pitfalls and analyzing the error message, you can take the first step towards resolving the issue.

In the next section, we'll explore some possible solutions to this problem.

Possible Solutions

Solution 1: Check Database Configuration

One possible solution is to check the database configuration. Make sure that the database is properly set up and configured. You can do this by checking the .env or the database connection settings in the project configuration.

Solution 2: Update Dependencies

Another possible solution is to update the dependencies. Make sure that all dependencies, including @rocicorp/zero, are up-to-date. You can do this by running the following command:

pnpm update

Solution 3: Reinstall Dependencies

If updating dependencies doesn't work, try reinstalling them. You can do this by running the following command:

pnpm install

Solution 4: Check Project Configuration

Finally, check the project configuration. Make sure that all configuration files, including .env files, are properly set up and configured. You can do this by checking the project configuration files or by running the following command:

pnpm config

Conclusion

Getting started with Drop-in can be a challenging experience, but by understanding the common pitfalls and analyzing the error message, you can take the first step towards resolving the issue. Remember to check the database configuration, update dependencies, reinstall dependencies, and check the project configuration. With these solutions, you should be able to resolve the issue and get started with Drop-in.
