## Usage
Send a simple query
```js
const graphql = require('@octokit/graphql')
const { repository } = await graphql(`{
repository(owner:"octokit", name:"graphql.js") {
issues(last:3) {
edges {
node {
title
}
}
}
}
}`, {
headers: {
authorization: `token secret123`
}
})
```
⚠️ Do not use [template literals](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals) in the query strings as they make your code vulnerable to query injection attacks (see [#2](https://github.com/octokit/graphql.js/issues/2)). Use variables instead:
```js
const graphql = require('@octokit/graphql')
const { lastIssues } = await graphql(`query lastIssues($owner: String!, $repo: String!, $num: Int = 3) {
repository(owner:$owner, name:$repo) {
issues(last:$num) {
edges {
node {
title
}
}
}
}
}`, {
owner: 'octokit',
repo: 'graphql.js'
headers: {
authorization: `token secret123`
}
}
})
```
Create two new clients and set separate default configs for them.
```js
const graphql1 = require('@octokit/graphql').defaults({
headers: {
authorization: `token secret123`
}
})
const graphql2 = require('@octokit/graphql').defaults({
headers: {
authorization: `token foobar`
}
})
```
Create two clients, the second inherits config from the first.
```js
const graphql1 = require('@octokit/graphql').defaults({
headers: {
authorization: `token secret123`
}
})
const graphql2 = graphql1.defaults({
headers: {
'user-agent': 'my-user-agent/v1.2.3'
}
})
```
Create a new client with default options and run query
```js
const graphql = require('@octokit/graphql').defaults({
headers: {
authorization: `token secret123`
}
})
const { repository } = await graphql(`{
repository(owner:"octokit", name:"graphql.js") {
issues(last:3) {
edges {
node {
title
}
}
}
}
}`)
```
Pass query together with headers and variables
```js
const graphql = require('@octokit/graphql')
const { lastIssues } = await graphql({
query: `query lastIssues($owner: String!, $repo: String!, $num: Int = 3) {
repository(owner:$owner, name:$repo) {
issues(last:$num) {
edges {
node {
title
}
}
}
}
}`,
owner: 'octokit',
repo: 'graphql.js'
headers: {
authorization: `token secret123`
}
})
```
Use with GitHub Enterprise
```js
const graphql = require('@octokit/graphql').defaults({
baseUrl: 'https://github-enterprise.acme-inc.com/api',
headers: {
authorization: `token secret123`
}
})
const { repository } = await graphql(`{
repository(owner:"acme-project", name:"acme-repo") {
issues(last:3) {
edges {
node {
title
}
}
}
}
}`)
```
## Errors
In case of a GraphQL error, `error.message` is set to the first error from the responses `errors` array. All errors can be accessed at `error.errors`. `error.request` has the request options such as query, variables and headers set for easier debugging.
```js
const graphql = require('@octokit/graphql').defaults({
headers: {
authorization: `token secret123`
}
})
const query = `{
viewer {
bioHtml
}
}`
try {
const result = await graphql(query)
} catch (error) {
// server responds with
// {
// "data": null,
// "errors": [{
// "message": "Field 'bioHtml' doesn't exist on type 'User'",
// "locations": [{
// "line": 3,
// "column": 5
// }]
// }]
// }
console.log('Request failed:', error.request) // { query, variables: {}, headers: { authorization: 'token secret123' } }
console.log(error.message) // Field 'bioHtml' doesn't exist on type 'User'
}
```
## Partial responses
A GraphQL query may respond with partial data accompanied by errors. In this case we will throw an error but the partial data will still be accessible through `error.data`
```js
const graphql = require('@octokit/graphql').defaults({
headers: {
authorization: `token secret123`
}
})
const query = `{
repository(name: "probot", owner: "probot") {
name
ref(qualifiedName: "master") {
target {
... on Commit {
history(first: 25, after: "invalid cursor") {
nodes {
message
}
}
}
}
}
}
}`
try {
const result = await graphql(query)
} catch (error) {
// server responds with
// {
// "data": {
// "repository": {
// "name": "probot",
// "ref": null
// }
// },
// "errors": [
// {
// "type": "INVALID_CURSOR_ARGUMENTS",
// "path": [
// "repository",
// "ref",
// "target",
// "history"
// ],
// "locations": [
// {
// "line": 7,
// "column": 11
// }
// ],
// "message": "`invalid cursor` does not appear to be a valid cursor."
// }
// ]
// }
console.log('Request failed:', error.request) // { query, variables: {}, headers: { authorization: 'token secret123' } }
console.log(error.message) // `invalid cursor` does not appear to be a valid cursor.
console.log(error.data) // { repository: { name: 'probot', ref: null } }
}
```
## Writing tests
You can pass a replacement for [the built-in fetch implementation](https://github.com/bitinn/node-fetch) as `request.fetch` option. For example, using [fetch-mock](http://www.wheresrhys.co.uk/fetch-mock/) works great to write tests
```js
const assert = require('assert')
const fetchMock = require('fetch-mock/es5/server')
const graphql = require('@octokit/graphql')
graphql('{ viewer { login } }', {
headers: {
authorization: 'token secret123'
},
request: {
fetch: fetchMock.sandbox()
.post('https://api.github.com/graphql', (url, options) => {
assert.strictEqual(options.headers.authorization, 'token secret123')
assert.strictEqual(options.body, '{"query":"{ viewer { login } }"}', 'Sends correct query')
return { data: {} }
})
}
})
```
