Drizzle ORM in 100 Seconds
Summary
TLDRDrizzle is a lightweight set of tools that enables type-safe object-relational mapping with databases like MySQL and PostgreSQL. It provides an API and TypeScript that closely matches the underlying SQL code, delivering type safety without abstraction overhead. Dedicated adapters for each database allow Drizzle to connect applications to cloud providers like RDS and Neon. An optional Prisma-like query API keeps data access concise. Drizzle Kit handles migrations. Drizzle Studio offers a GUI for local data management. The video demonstrates using Drizzle and Neon to define a schema, generate migrations, insert seed data, and run type-safe queries.

Q & A
What problem does Drizzle aim to solve?
-Drizzle aims to solve the problem of complexity and performance overhead with traditional object-relational mapping (ORM) libraries when working with SQL databases.
How does Drizzle provide a simple yet powerful API?
-Drizzle provides dedicated adapters for each database, as well as type safety and intellisense, without heavy abstractions on top of the native SQL.
What databases does Drizzle support?
-Drizzle supports popular relational databases like MySQL, PostgreSQL, and SQLite.
What tools does Drizzle offer in addition to the core library?
-Drizzle offers optional tools like a Prisma-like query API, a CLI for database migrations called Drizzle Kit, and Drizzle Studio for data management.
What JavaScript runtimes can you use Drizzle with?
-Drizzle can run on Node.js, Bun, Dino, and edge runtimes like Cloudflare Workers.
How do you define the database schema with Drizzle?
-The database schema is defined using TypeScript code and functions like pgTable() and relations() to set up tables, columns, constraints, and relationships.
What does the drizzle-kit generate command do?
-The drizzle-kit generate command converts the TypeScript schema definitions into SQL migration files that can be applied to the database.
What makes Neon a good database choice to use with Drizzle?
-Neon is easy to use, has a generous free tier, provides a fast serverless database driver, and has a dedicated Drizzle adapter and tutorial.
What are some key benefits of using Drizzle?
-Key benefits are type safety, intellisense, avoiding ORM abstraction drawbacks, dedicated adapters for each database, and optional tools like Drizzle Studio.
What is required to get started with Drizzle?
-To get started you need to install Drizzle and a compatible database driver, connect to the database, define a schema, run migrations to set up tables, and then start executing queries.

😀 Introducing drizzle - a lightweight ORM for relational databases
Paragraph 1 introduces drizzle, a lightweight object-relational mapping (ORM) tool that makes working with relational databases like MySQL, PostgreSQL, and SQLite simpler and more type-safe. It provides closely matched APIs and TypeScript to the underlying SQL code for benefits like intellisense without unnecessary abstractions. It has adapters for different databases and tools for cloud hosts like RDS and Fly.io. It also offers optional query APIs and a CLI for migrations and data management.

Highlights
Drizzle is an ORM that provides a SQL-like API and TypeScript types without complex abstractions
Instead of a single API, Drizzle has dedicated adapters for each database along with tools for popular cloud hosts
It also provides an optional Prisma-like query API for concise data fetching and joins
Drizzle Studio is a GUI for managing your data locally
You'll first need a relational database like Neon, which has a generous free tier
Define schema tables with PG table function - columns get SQL constraints via JS functions
References between tables create relationships with foreign keys
Relations function simplifies relational queries and joins
Drizzle kit generate creates migration files to apply schema to the database
Strongly typed schema prevents incorrect queries
Query API handles one-to-one, one-to-many and many-to-many relationships

Drizzle solves object-relational mapping without unnecessary overhead or leaky abstractions
Keeps data access code type-safe with intellisense while matching the underlying SQL
Optional higher-level abstractions keep application code concise and readable

drizzle om a lightweight set of tools
that makes type safe object relational
mapping with your favorite relational
database fun again most apps in the real
world rely on databases like MySQL
postgressql and SQL light to store their
critical user data but working with raw
SQL can be painful and even
life-threatening when you screw up over
the decades hundreds of libraries have
been built to abstract away SQL code to
hide its complexity inside your favorite
objectoriented programming language this
technique is called object relational
mapping it's great and null but can
often bring unnecessary performance
overhead and cause leaky abstractions
because the developers have no idea how
their underlying SQL code actually works
drizzle is an omm that takes the
opposite approach it provides an API and
typescript that closely matches the
native underly SQL code this gives you
the benefits of type safety and
intellisense without all the crazy
abstractions but how is that possible
when every database is different instead
of trying to jam everything into a
single API drizzle provides dedicated
adapters for each one of them along with
dedicated tools for popular Cloud hosts
like RDS and neon but if this code looks
too raw and uncensored for you it also
provides an optional Prisma likee query
API that keeps your data fetching and
join code concise and readable in
addition it provides an optional CLI for
handling database migrations called
drizzle kit but the cherry on top is
drizzle Studio A guey you can run
locally to manage your data to get
started you'll first need a relational
database I'm going with neon my go-to
pick for a postgress database and the
sponsor of today's video neon is awesome
because it's easy to use there's a
generous free tier and it even has a
fast serverless driver with a drizzle
adapter you don't even need to install
postgress locally just create a new
database on the dashboard both drizzle
and neon are designed to run on any
JavaScript runtime like node.js bun and
Dino as well as Edge run times like
cloudflare workers now install drizzle
and your database driver then connect to
the database in your typescript code we
could start making queries now but we
don't have any data yet first we need a
schema create a schema file then Define
tables with the PG table function each
table table has a name followed by
columns defined in this JavaScript
object columns are given constraints
with JavaScript functions that match
their SQL equivalents once a table is
defined we can reference it in other
tables to create relationships with
foreign keys and optionally we can use
the relations function to simplify
relational queries and Joints now let's
convert this typescript code into
postgressql by running the drizzle kit
generate command that creates a
directory with our migration files which
we can then apply to Neon with this
migrate function and now we can use
drizzle SQL like a to insert data into
the database and because the schema is
strongly typed it's impossible to write
incorrect queries in addition because we
also created a relation in our schema we
can use the query API to fetch records
based on one to one one to many or many
to many relationships this has been
