Post mutation to graphql with axios

Question

This query in grahiql works:

mutation {
  addSkill(id:"5",name:"Javascript",level:1,type:"frontend") {
    status
    id
    name
    level
    type
  }
}

What is the equivalent to post with axios?

I've tried this, but keep getting a 400 request response.

{"errors":[{"message":"Syntax Error: Unterminated string.","locations":[{"line":3,"column":82}]}]}

This is what I tried:

axios
  .post(config.apiendpoint, {
    query: `
      mutation addSkill($id:String!, $name:String!, $level:Float!, $type:String!) {
        mutation addSkill(id:$id, name:$name", level:$level, type:$type) { 
          status
          id
          name
          level
          type
        }
      }
    `,
    variables: {
      id: String(id),
      name: this.form.name,
      level: this.form.level,
      type: this.form.type,
    },
  })
  .then(res => console.log(res))
  .catch(err => console.log(err))

Am sure the values in the variables are of the right type and is not empty too.

I would avoid including variables directly in the query like this, because that way you have to constantly adjust how your variables fit into the template literal, like stringifying stuff and adding quotes.

Use graphql print to do it for you!

Try this:

import axios from 'axios';
import { print } from 'graphql';
import gql from 'graphql-tag';

const ADD_SKILL = gql`
mutation addSkill($id:String!, $name:String!, $level:Float!, $type:String!) {
  addSkill(id:$id, name:$name, level:$level, type:$type) { 
    status
    id
    name
    level
    type
  }
}
`

axios.post(config.apiendpoint, {
  query: print(ADD_SKILL),
  variables: {
    id: String(id),
    name: this.form.name,
    level: parseFloat(this.form.level),
    type: this.form.type,
  },
})
.then(res => console.log(res))
.catch(err => console.log(err))
