Language format for the date in GraphQL

[MaralS]

Description

For a client, I'm using this amazing framework to build a fast web app. However, I'm beginning with GraphQL. I noticed that the date is formatted to display months in English. I wanted to know which parameters is necessary to display the date in french.

Environment

Gatsby version: 1.1.27
Node.js version: 8.9.3
Operating System: OS X El Capitan 10.11.6

File contents (if changed):

gatsby-node.js:

const path = require('path');

exports.createPages = ({ boundActionCreators, graphql }) => {
const { createPage } = boundActionCreators;

const blogPostTemplate = path.resolve(`src/templates/blog-post.js`);

return graphql(`{
allMarkdownRemark(
  sort: { order: DESC, fields: [frontmatter___date] }
  limit: 1000
) {
  edges {
    node {
      excerpt(pruneLength: 250)
      html
      id
      frontmatter {
        date
        path
        title
      
      }
    }
  }
}

}`)
.then(result => {
if (result.errors) {
return Promise.reject(result.errors);
}

        result.data.allMarkdownRemark.edges
            .forEach(({ node }) => {
                createPage({
                    path: node.frontmatter.path,
                    component: blogPostTemplate,
                    context: {} // additional data can be passed via context
                });
            });
    });

}

GraphQL Query :

export const pageQuery = graphql`

query BlogPostByPath($path: String!) {
markdownRemark(frontmatter: { path: { eq: $path } }) {
html
frontmatter {
date(formatString: "DD/MM/YYYY")
path
title

    image{
      childImageSharp{
        sizes(maxWidth: 1000, quality: 100, cropFocus: CENTER, toFormat: JPG) {
            ...GatsbyImageSharpSizes
        }
        responsiveSizes(quality: 70){
          src
          srcSet
        }
      }
    }
  }
}

}
`;

Actual result

I just have the month date like DD/MM/YYYY with numbers like 12/05/2017.

Expected behavior

I wanted to show the date like : 12 mai 2017

Thank you in advance for your help,

kind regards,

Maral.

The GraphQL date field takes an optional locale argument for modifying how the date is formatted #2652

Good luck with the client site!

Is it possible to show how to get this working on my example? I'm trying to sort on the "datumString"which has a format like "01-12-2018" (first of december, 2018).

{
  allThirdPartyClubwedstrijden(
    sort: {fields: datumString, order: ASC}
    filter: {
      uitslag: {eq: ""}
      datumString: {ne: null}
    }
    limit: 5
  ){
    edges {
      node {
        datumString
        tTNaam
        tUNaam
        uitslag
        beginTijd
      }
    }
  }
}
