I have a problem and I need to transform a query graphql to a json object. That is, I get a query in the following way and I would like to have a json of that query. How could I do it? I've been searching and I haven't found a way.
Thank you.
query {
Patient(id:4){
id
birthDate {
year,
day
}
name {
text
}
}
}
Any GraphQL document, whether it's a query or a schema, can be represented as an AST object. This is the standard way to represent a GraphQL document as an object. You can parse a document string into an object using the core library:
const { parse } = require('graphql')
const object = parse(`
query {
# ...
}
`)
The object can be converted back into a string as well:
const { print } = require('graphql')
const string = print(object)
GraphQL does not define a JSON standard for queries.
If you want to express a graphQL in JSON, you can define your own structure and write your own serializers. but it will not be supported by any graphQL service
EDIT: I found an NPM package that does that. It is not a standard whatsoever, but if you really need it, you can use this package: https://www.npmjs.com/package/json-to-graphql-query
There is an online converter:

But if use token address, you need add backslash before double quotes (tested in postman). For example this is graphql query:
{
pairs(where: {token0: "0x1381f369d9d5df87a1a04ed856c9dbc90f5db2fa", token1: "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"}) {
token0 {
name
symbol
}
token0Price
token1 {
name
symbol
}
token1Price
}
}
And this is result of conversion to JSON from previous link:
{
"query": "{ pairs(where: {token0: "0x1381f369d9d5df87a1a04ed856c9dbc90f5db2fa", token1: "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"}) { token0 { name symbol } token0Price token1 { name symbol } token1Price }}"
}
Just add backslashes before double quotes near token addresses. Result:
{
"query": "{ pairs(where: {token0: \"0x1381f369d9d5df87a1a04ed856c9dbc90f5db2fa\", token1: \"0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2\"}) { token0 { name symbol } token0Price token1 { name symbol } token1Price }}"
}
According to the documentation: to POST a graphQL query to a webservice in a JSON body, simply remove all newlines from the graphQL query, then put it in the following JSON:
{
"query": "[graphQL query here]",
"variables": {}
}
In your case, this would look like:
{
"query": "query { Patient(id:4){ id birthDate { year, day } name { text } } }",
"variables": {}
}
Invalid Syntax. I had to use it without square brackets: { "query": "graphQL query here", "variables": {} } for it to work.
