Zod Schema

zod-schema provides a powerful and flexible way to implement schema validation for Meteor collections using the popular zod library. This package allows developers to define schemas for their collections, ensuring that the data being inserted or updated adheres to specified rules and types.

Key Features:

• Schema Validation: Automatically validate documents against defined schemas when inserting or updating, helping to catch errors early in the development process.
• Soft Delete Support: Easily implement soft delete functionality with the withSoftDelete method, allowing you to mark documents as deleted without removing them from the database.
• Date Tracking: Automatically add created and updated timestamps to your documents with the withDates method.
• User Context: Track which user created a document with the withUser method, enhancing accountability and traceability.
• Flexible Validation: Skip schema validation when necessary, providing flexibility for specific use cases.

Installation

To add this package to your Meteor project, run:

How to install:

meteor add pmogollons:zod-schema

Usage

To use the zod-schema package in your Meteor project, follow these steps:

1. Define Your Schema: Use the zod library to create a schema for your collection. For example:

   1import { z } from "zod";
   2
   3const userSchema = z.object({
   4  name: z.string(),
   5  age: z.number(),
   6});

2. Create a Collection: Create a new Mongo collection and apply the schema using the withSchema method.

   1const UserCollection = new Mongo.Collection("users");
   2UserCollection.withSchema(userSchema);

3. Insert Documents: When inserting documents, the package will automatically validate them against the defined schema.

   1await UserCollection.insertAsync({ name: "Alice", age: 30 }); // Valid
   2await UserCollection.insertAsync({ name: "Bob", age: "thirty" }); // Throws ValidationError

4. Update Documents: Similarly, updates will also be validated.

   1const userId = await UserCollection.insertAsync({ name: "Charlie", age: 25 });
   2await UserCollection.updateAsync(userId, { $set: { age: 26 } }); // Valid
   3await UserCollection.updateAsync(userId, { $set: { age: "twenty-six" } }); // Throws ValidationError

5. Optional Features: You can also use additional features like soft deletes and date tracking:

   1UserCollection.withSoftDelete();
   2UserCollection.withDates();
   3UserCollection.withUser();

6. Skip Validation: If you need to skip validation for specific operations, you can do so by passing the skipSchema option:

   1await UserCollection.insertAsync({ name: "David", age: "35" }, { skipSchema: true });

7. Soft Delete: You can also use the recoverAsync method to recover a soft deleted document.

   1await UserCollection.recoverAsync({ _id: deletedUserId });

Caveats

• Not all mongo update operators are supported yet. This operations are not validated: ($unset, $inc, $mul, $rename, $min, $max, $currentDate, $, $[], $pop, $pull, $pullAll, $bit)
• When using soft delete we add an isDeleted field, when querying the collection you should add the isDeleted: false filter when you want to get the not deleted documents.
• If you are using pmogollons:nova any collection that uses soft delete will automatically add a isDeleted filter to the root collection of your query.
