In a react / gatsby / wordpress project, I need to pull data from a 3rd party, non-graphql API. I am attempting to parse the data returned from this API and make it available for use with graphql.
I'm following the accepted answer in this post: GatsbyJS getting data from Restful API
The error I'm receiving is:
res.data.full_options.map is not a function
Here's my code thus far:
exports.sourceNodes = async ({ actions }) => {
const { createNode } = actions;
const fetchJoinOptions = () => axios.get(`https://example.com/path/to/api`)
const res = await fetchJoinOptions()
console.log(res.data)
res.data.full_options.map((option, i) => {
})
}
console.log(res.data) outputs the following:
{
join_options: { '76': 'Yearly Membership', '366': 'Halloween Sale - 50% Off!' },
full_options: {
'76': {
optionid: '76',
siteid: '15',
networkid: '0',
deleted: '0',
enabled: '1',
orderid: '1',
option_type_id: '0',
billerid: '0',
programid: '0',
legacy: '0',
details: [Object]
},
'97': {
optionid: '97',
siteid: '15',
networkid: '0',
deleted: '0',
enabled: '1',
orderid: '43',
option_type_id: '0',
billerid: '0',
programid: '0',
legacy: '0',
details: [Object]
},
'190': {
optionid: '190',
siteid: '15',
networkid: '0',
deleted: '0',
enabled: '1',
orderid: '44',
option_type_id: '0',
billerid: '0',
programid: '0',
legacy: '0',
details: [Object]
}
},
default_option: '76',
special_options: { '236': 'Join with Gift Card' }
}
Here's the error in it's entirety:
ERROR #11321 PLUGIN
"gatsby-node.js" threw an error while running the sourceNodes lifecycle:

Could you please explain how I can map this data?
CodePudding user response:
You need to convert your response in Object.entries
or Object.values
because getting a response in Object
format not Array
.
Object.entries() and Object.values()
Example :
Object.entries()
const object1 = {
a: 'somestring',
b: 42
};
for (const [key, value] of Object.entries(object1)) {
console.log(`${key}: ${value}`);
}
// expected output:
// "a: somestring"
// "b: 42"
Object.values()
const object1 = {
a: 'somestring',
b: 42,
c: false
};
console.log(Object.values(object1));
// expected output: Array ["somestring", 42, false]
CodePudding user response:
I think that problem is that you try to iterate over object, try something like:
const output = Object.keys(res.data.full_options).map((key)=>{
something(res.data.full_options[key]) //something you want to do with this value
})
CodePudding user response:
The issue is here:
full_options: {
here full_options
is not an array its an object and map()
works on array.
To handle this, try Object.values
on full_options
, it will return an array and on array you can call map()
function.
