Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
mapstructure
- How do I marshal a JSON array into a map?
-
Is there any equivalent to pydantic, serde, etc?
Maybe https://github.com/mitchellh/mapstructure can do what you want? It has some options for Remainder Values and Omit Empty
-
Struggling to get JSON response data into usable struct
I've tried using mapstructure to then marshal the map fields into a struct which mostly works (it struggles with times and custom time types which requires a workaround for each case), but this doesn't feel very idiomatic and requires two passes at marshaling.
-
Return unstructed db rows to struct
Although some orders may have more records maybe a superset can be indentified that you can actually create a struct of it and after gathereing first all values into a map then convert it to a struct maybe using a library like https://github.com/mitchellh/mapstructure . this way you can at least isolate the non structured data only on the data extraction part and the rest of your application can work with well formed structs.

Trying to print JSON data from a file
Alternatively, you could try https://github.com/mitchellh/mapstructure if you don't know what your incoming structure is
-
How to ensure required fields in struct consistently?
I'm doing it by validating a map[string]any first then putting it into a structure using mapstructure. It covers most use-cases and offers the most flexibility, at the expense of a bit of performance.
-
Question about Unmarshalling
That said, it is possible to do this with JSON using something like https://github.com/tidwall/gjson or if you are fine with the switch statement but don't want to marshal and unmarshal again: https://github.com/mitchellh/mapstructure
-
What type of software do you write at your workplace?
https://github.com/mitchellh/mapstructure because we have JSON documents which contain rugged arrays ;-)
-
Help with mapstructure.Decode()
I've been using mapstructure.Decode to great effect, but currently can't figure out why a given mapping doesn't work. I'd appreciate it if someone could point out wtf I'm doing wrong or at least in the right direction:
-
map[string]interface{} decoder
What do you mean by "decode"? I've used https://github.com/mitchellh/mapstructure but that doesn't quite look like what you're doing.

Authentication system using Golang and Sveltekit - Initialization and setup
Following the completion of the series — Secure and performant full-stack authentication system using rust (actix-web) and sveltekit and Secure and performant full-stack authentication system using Python (Django) and SvelteKit — I felt I should keep the streak by building an equivalent system in PURE go with very minimal external dependencies. We won't use any fancy web framework apart from httprouter and other basic dependencies including a database driver (pq), and redis client. As usual, we'll be using SvelteKit at the front end, favouring JSDoc instead of TypeScript. The combination is ecstatic!

Connect REST API to database with Go
Go’s standard library was not built to include any specific database drivers. So we need to install a third party package. In this case we are going to install https://github.com/lib/pq. Run following command:
-
Getting EOF when connecting to a database using sqlx
For Postgres the driver comes from "github.com/lib/pq" and then it is just "postgres".
-
Is this a proper setup in Go for a postgres api?
With regards to 2. -- also, it looks like there's an important unfixed issue https://github.com/lib/pq/issues/939. I haven't verified whether the issue is up to date.
