Setup

> Make sure your mysql database is accessible everywhere you are planning to build your site from.

Within plugins in the gridsome-config.js file, add the connection settings and queries for the data you need.

``javascript:title=gridsome-config.js
// gridsome-config.js

module.exports = {
plugins: [
{
use: 'gridsome-source-mysql',
options: {
connection: {
host: 'localhost', // required
port: 3306,
user: 'root', // required
password: 'secret', // required
database: 'my_db', // required
connectionLimit : 10
},
debug: true, // Default false on production
ignoreImages: false, // Do not download any images
imageDirectory: 'sql_images',
regex: /()_\d(.(jpg|png|svg|jpeg))/i, // Default false
queries: [ // required
{
name: 'Author',
route: '/authors/:path',
path: 'fullname',
sql: SELECT id, fullname, avatar, url FROM author,
images: ['avatar'] // Default []
},
{
name: 'Post',
path: 'title',
sql: SELECT id, title, image, gallery, author as author_id, excerpt, body, created FROM post WHERE published = ?,
args: [1],
images: ['image', ['gallery']] //Gallery contains comma delimited string of image url.
}
]
}
}
]
}
`

Relationship ids should be in the format of xxx_id where xxx is the name of another query.

Usage

On the above example two content types will be created Post and Author with author_id being a relation:

`
query {
allPost {
edges {
node {
title
path
image (width: 600, height: 600)
gallery {
index
image (width: 400, height: 400)
}
excerpt
author {
fullname
url
avatar (width: 100, height: 100)
}
}
}
}
}
`

Definitions

regex: Specify false to not use or a regex expression that has 2 capture groups. This can be used to remove duplicate files for example the value /()_\d(.(jpg|png|svg|jpeg))/i renames all files that end with _\d eg. _1, _2; since we assume them to be duplicate files. We DO NOT change the source url since it might be the original file (not ending with _\d) isn't used.

Field | Type | Info
---|---|---
name | string | Name of the resulting content type
route? | string | Specify a dynamic route structure eg. /blog/:path
path | function(slugify, row, parentRow?): string | Return the path for the given row
path | { prefix?: string, field: string, suffix?: string } | field should exist on each row and will be slugified
path | string | Name of a field on each row to slugify and use as path
sql | string | A SQL Query with optional placeholders ? which will be replaced by args in order
args? | array | Simple array of static values
args? | function(parentRow?): array | Return array of values based on data from the parentRow or dynamic calculated data, eg. [Date.now()]
json? | array | Names of fields that contain JSON strings to convert into an object or else null
images? | array | Names of fields on rows that contain urls of images to download and optimize via Gridsome
subs | array | Array of Query to execute per result of the current query

MySQL Query Examples

Generate comma seperated urls and ids

The following is an example of how you can generated the fields for using as a one-to-many relationship in graphql and also joining image urls.

`
queries: [
{
name: 'Product',
path: 'slug',
images: ['image', ['gallery']] // Default []
sql: SELECT
pc.product_id as id,
cats.category_ids,
pc.sku,
pc.name,
pc.price,
pc.slug,
CONCAT('https://example.com/media/', pc.image) as image,
media.images as 'gallery',
FROM product_catalog pc
INNER JOIN (
SELECT product_id, GROUP_CONCAT(CONCAT('https://example.com/media/catalog/product',value)) AS 'images'
FROM product_media
GROUP BY product_id
) media
ON media.product_id = pc.product_id
INNER JOIN (
SELECT product_id, GROUP_CONCAT(category_id) AS 'category_ids'
FROM product_category
GROUP BY product_id
) cats
ON cats.product_id = pc.product_id
WHERE pc.status = 1
},
{
name: 'Category',
route: '/category/:path',
path: 'path',
images: [(row, addImageUrl) => {
if (row['image']) {
row['image'] = addImageUrl(https://example.com/media/${row['image']})
}
}],
sql: SELECT
category_id AS 'id',
name,
image,
parent_id AS 'category_id',
position,
level,
product_count AS 'count'
FROM category_catelog
WHERE active = 1
}
]
`

In the above example cats.category_ids will result in an array of Category content types if you have specified a query for Category

Images in this database were relative, so in order for them to be downloaded they need to be concatenated with the site origin.

In the Category query, we change the parent_id to output as category_id since we want it to be linked to another Category` automatically.
