Possible disadvantages of Postgres.js

  • Learning Curve
    Developers who are new to this library might face a learning curve as it might differ from other more commonly used PostgreSQL libraries.
  • Maturity
    Compared to older libraries like node-postgres (pg), it might lack the extensive documentation and long-term usage by large projects.
  • Niche Use Case
    May not be the best fit for applications that require a middleware ORM or the abstractions provided by traditional ORMs.
  • Smaller Ecosystem
    While it is growing, the ecosystem of third-party tools and plugins is not as large as those for some established libraries.

  • Why Node.js needs a virtual file system
    Bun provides native MySQL, SQlite, and Postgres drivers. I'm not saying Node should support every db in existence but the ones I listed are critical infrastructure at this point. When using Postgres in Node you either rely on the old pg which pulls 13 dependencies[1] or postgres[2] which is much better and has zero deps but mostly depends on a single guy.

  • Show HN: Pg-typesafe โ€“ Strongly typed queries for PostgreSQL and TypeScript
    Is there a way to make this work with https://github.com/porsager/postgres ? It's very close to raw SQL but with safe substitutions. I use it with Zod, but it would be great to have the types derived automatically. - Source: Hacker News / 5 months ago
  • Pipelining in psql (PostgreSQL 18)
    I really want to use pipelining for our "em.flush" of sending all INSERTs & UPDATEs to the db as part of a transaction, b/c my initial prototyping showed a 3-6x increase: https://joist-orm.io/blog/initial-pipelining-benchmark/ If you're not in a transaction, afaiu pipelining is not as applicable/useful b/c any SQL statement failing in the pipeline fails all other queries after it, and imo it would suck for... - Source: Hacker News / 9 months ago
  • Node.js can now execute TypeScript files
    > What are you missing? Everything else needed to make a backend app. At the very least, Node should provide fundamental pieces like database drivers. Currently the best PG driver[1] depends on a single guy. Bun already provides its own PG driver [2] and Jarred has written they will keep investing into more built-in APIs.

  • Neon Is Generally Available: Serverless Postgres
    I want to use this as a chance to bring attention to a GitHub issue that I think would help reduce friction for Neon: https://github.com/neondatabase/neon/issues/4989. Having run a local dev environment connected to Neon and tests connected to Neon got in our way of adoption. We'd prefer to develop and run tests against a regular Postgres localhost database. To the PMs of Neon, put yourself in the shoes of a new... - Source: Hacker News / over 2 years ago

  • Exploring Goja: A Golang JavaScript Runtime
    I work on the D2 project ([0]) and we switched from other Javascript runners (v8go) to Goja. Using a JS runtime with a dependency on cgo means your Go program loses the (huge) benefit of cross-compiling to different architectures, since at build time it gets linked to the architecture-specific libc. If you're interested in some production code with Goja, this is our code for calling RoughJS [1] from Go in order to... - Source: Hacker News / almost 2 years ago
  • I want to contribute to open source but don't know where to start
    You're welcome in D2! I maintain a Text to diagram language, released a few months ago, 13k+ stars, I'm actively tagging issues that are good first issues, clean well-tested Go, and I'm happy to help you get that first merge in. Feel free to chime in on any issue that looks interesting! https://github.com/terrastruct/d2. Source: about 3 years ago
  • Concrete Diagramming, a Lightweight Alternative to C4
    Right. It's okay to leave written documentation on SaaS (e.g. Notion), because the text is the artifact. If they're shutting down, or I don't like them anymore, I just move the text. But if Ilograph goes down, all I have is useless YAML. Our team went through this thought process when we decided to open source our text-to-diagram language, users need to be able to reproduce their docs even if we shut down... - Source: Hacker News / over 3 years ago
