Tips for incorporating SectionList sections in React Native using an array

I am working with an array of objects named movies (const movies = movie[]). Each movie object includes properties like name, description, date and duration.

  movie: {
    name: string;
    description: string;
    date: Date;
    duration: number
  }

My goal is to utilize a React Native SectionList component to create sections based on the movie's date:

**20 june 2020:**

Movie name | description | duration

Movie name | description | duration

**18 april 2020:**

Movie name | description | duration

Movie name | description | duration

...

How can I generate these sections and group my movies by date? I attempted using lodash with const groupedMovies = groupBy(movies, movie => movie.date), but it resulted in a collection and not an array.

Reference: https://reactnative.dev/docs/sectionlist

typescript react-native lodash react-native-sectionlist

Answer №1

If you're looking to transform the data structure from:

{
   "18 april 2020": [{...}, {...}, {...}],
   ...
}

to this format:

[
   { "title": "18 April 2020", "data": [{...}, {...}, {...}] },
   ...
]

You can achieve this conversion using the following code snippet:

const groupedMovies = groupBy(movies, movie => movie.date);
let data = Object.entries(groupedMovies).map(([key, value]) => ({ title: key, data: value }))

Alternatively, you can also use lodash's map function like so:

const groupedMovies = groupBy(movies, movie => movie.date);
let data = map(groupedMovies, (value, key) => ({ title: key, data: value }))
