GraphQL Query Recipes
This document contains common GraphQL query recipes for you to use or take example of. You should read the "Managed IoT Cloud - GraphQL API" first so you know how to run the following queries.
1. Query all rules available to the currently authorized user. Sort by rule name.
MIC.graphql({
query: `
query ($sort: String) {
allRules(searchOptions: { sort: $sort }) {
name
description
id
enabled
}
}
`,
variables: {
sort: 'name'
}
})2. Query all resources created for (or by) the Thing Type "490".
MIC.graphql({
query: `
query thingTypeResources($thingTypeId: String!) {
thingTypeResources(thingTypeId: $thingTypeId) {
resources {
id
name
type
metadata {
label
unit
isSettable
isVirtual
custom {
label
value
}
}
}
}
}
`,
variables: {
thingTypeId: '490'
}
})3. Query for the first page of all online Things for the Thing Type ID "490". Use "Oslo/Europe" as the time-zone and sort by Thing label name.
MIC.graphql({
query: `
query allThings(
$searchOptions: ListThingsSearchOptions,
$timezone: String
) {
allThings(searchOptions: $searchOptions) {
pageInfo {
page
pages
size
itemCount
totalCount
}
things {
thingName
label
domain
domainConnection {
name
}
thingTypeConnection {
label
}
thingType
lastHeardFrom(
momentFunction: {
name: fromNow,
arguments: "true",
timezone: $timezone
}
)
createdAt(
momentFunction: {
name: fromNow,
arguments: "true",
timezone: $timezone
}
)
state
description
hasNetworkedThings
parentThingName
}
}
}
`,
variables: {
searchOptions: {
filter: {
thingTypes: ['490'],
thingStatus: -1
},
paging: {
page: 1
},
sorting: {
sort: 'label.lowercase'
}
},
timezone: 'Europe/Oslo'
}
})4. Query for all information of a Thing with the Name "00001341".
MIC.graphql({
query: `
query thing($thingName: String!) {
thing(thingName: $thingName) {
shadow
domainTopic
domain
label
thingName
createdAt
thingType
parentThingName
hasNetworkedThings
description
thingTypeConnection {
resourcesConnection {
resources {
id
name
type
subthingType
metadata {
label
unit
isSettable
isVirtual
custom {
label
value
}
}
}
}
}
networkedThingsConnection {
pageInfo {
page
pages
size
itemCount
totalCount
}
things {
label
thingName
thingType
hasNetworkedThings
}
}
}
}
`,
variables: {
thingName: '00001341'
}
})5. Query observations (using Elasticsearch) for a Thing with Name "00001341" and Type "490". Restrict the observation results to 100 hit per page and a resource called "pm25". Specify a "from" and "to" date. Sort by timestamp in descending order.
MIC.graphql({
query: `
query (
$thingName: String!,
$thingType: String!,
$resourceStatePath: String!,
$from: String!,
$to: String!,
$timestampFormat: String,
$timezone: String
) {
thingObservations(
searchOptions: {
filter: {
thingName: $thingName,
period: {
from: $from,
to: $to
},
resources: [$resourceStatePath],
thingTypes: [$thingType]
},
paging: {
size: 100
},
sorting: {
sort: "-timestamp"
}
}
) {
pageInfo {
totalCount
}
observations {
timestamp(
momentFunction: {
name: format,
arguments: [$timestampFormat],
timezone: $timezone
}
)
state
}
}
}
`,
variables: {
thingType: '490',
thingName: '00001341',
resourceStatePath: 'pm25',
from: '2019-03-09T23:00:00.000Z',
to: '2019-03-17T20:58:53.922Z',
timezone: 'Europe/Oslo'
}
})
