While following the Apollo basics tutorial, I tried to run
$ npx apollo service:push --graph=neo4j --key=user:<user>:<hash> --localSchemaFile=src/schema.graphql
from my repo created by following grand-stack-starter.
It fails with the following error:
Is it not possible to use the Apollo Graph Manager with a GRANDstack? Or could you explain how to configure the graph manager with these neo4j-graphql specific directives?
First off, thanks for this project! I had taken a few tutorials and mashed them together and had a somewhat working Neo4j backed GraphQL API running. However, this project has closed a lot of missing parts.
Is there any guidance on how to add additional data sources?
I can't seem to figure out how to have makeAugmentedSchema
work with other sources.
App and Neo4j sandbox are running condition
npm run seedDb cause following error on WSL:

I tried adding "--output public" to "build", but it didn't help.
I took two hours to carefully read code here, the Grandstack book, docs on grandstack.io.
I read docs on graphl-yoga and created my graphql with all the context for a couple of hours.
I brought in my resolvers to do some basic stuff including mutations
Finally I got a hang of the seed-db
I got my hands dirty with firebase + firebase admin SDK with everything learnt.
I now see GrandStack
at the end of the tunnel
The GraphQL schema was updated slightly - ensure the Angular client works with the updated schema.
I used an alias in my graphql query but all the react queries failed
because the sorting has to contain the original name not the alias.
Not sure if that's an issue with react passing the order by as a parameter, I think rather that neo4j-graphql-js should take the alias into account.
const GET_USER = gql`
query usersPaginateQuery(
$first: Int
$offset: Int
$orderBy: [_UserOrdering]
$filter: _UserFilter
) {
User(first: $first, offset: $offset, orderBy: $orderBy, filter: $filter) {
id
name: display_name
reputation
}
}
`
changes I had to make (from "name" to display_name
function UserList(props) {
const { classes } = props
const [order, setOrder] = React.useState('asc')
const [orderBy, setOrderBy] = React.useState('display_name') // <- here
<TableCell
key="name"
sortDirection={orderBy === 'name' ? order : false}
>
<Tooltip title="Sort" placement="bottom-start" enterDelay={300}>
<TableSortLabel
active={orderBy === 'name'}
direction={order}
onClick={() => handleSortRequest('display_name')} <!-- here -->
>
Name
</TableSortLabel>
</Tooltip>
</TableCell>
this makes it kinda inconsistent and hard to reason about.
##Also Error Handling
When the errors occurred I only saw Error
in the UI, no error message, not even in chrome debug tools
I had to run the query with the params from the react app manually against the graphql api to see the error message
it was also no error output in the terminal of api
or web-react
, even as it was running in dev-mode.
And no "errors" response data, but an HTTP 400
Deploy is failing on Now
Did you help with this error?
I'm fascinated by this Nietzsche combination, a powerful technology bomb. I'm trying to upload everything to see how it works and do this project here in GRANDstack.

Hi,
I'm struggling to setup a local docker environment using a neo4j enterprise image.
A local environment without docker seems to work:
systemctl start neo4j
npm start
, then from another pane npm run seedDb
{
data: {
u1: { id: 'u1', name: 'Will', __typename: 'User' },
...
}
}
And I can query the data from the graphql playground.
A mixed solution with API in docker connecting to local systemd neo4j fails. That's because my API docker container's localhost is different from my host localhost, and cannot query it. Not sure how to fix it, but I'd rather not end up with this solution.
When I try to use your docker-compose.yml example with neo4j and API containers, and replace the neo4j image with enterprise (also needed to add curl that's removed from the enterprise image), I fail to start the local fleet:

The java traceback error makes very little sense to me. I first thought it was due to file permissions when using volumes, but commenting that part didn't change the error.
Any idea how should I debug this?
I downloaded the latest repo and have been unable to get localhost:4000 to resolve. This should start the GraphQL API in the foreground. Instead, the error is 'Unable to connect'. After reviewing the git page, it appears work was done on ui (last update was 8 days ago). However, the api has not been updated for 2 months.
Under the Docker Compose section of the README the instructions says to make changes to the api/.env. Does that still apply after the latest commit?
looks like some incompatibility in relations usage here
for example:
type Review {
id: ID!
user: User @relation(name: "WROTE", direction: "IN")
}
when seed tried to add relation:
ar8:AddUserReviews(from:"u4",to:"r8"){id}
a bunch of validation errors happens
"Unknown argument \"userid\" on field \"AddUserReviews\" of type \"Mutation\"."
"Cannot query field \"id\" on type \"_AddUserReviewsPayload\".",
"Field \"AddUserReviews\" argument \"from\" of type \"_UserInput!\" is required but not provided.",
"Field \"AddUserReviews\" argument \"to\" of type \"_ReviewInput!\" is required but not provided.",
I inspected schema and its looks like
AddUserReviews(
from: _UserInput!
to: _ReviewInput!
): _AddUserReviewsPayload
when i try to open http://localhost:3000 the UI shows only the message "Error".
When debugging the XHR i see the attached error message.

So I do as directed, however when I fire up the graphql server and check out the schema, I get queries like Review , User etc which I suspect point to the Yelp dataset. Also the React App just renders error and the console shows the following:
[GraphQL error]: Message: The client is unauthorized due to authentication failure., Location: [object Object], Path: User
I've run into an issue with deploying to Zeit now. They updated their platform to v2 and now when I deploy I just get a set of static files on Zeit now.
I tried to launch the grand-stack-starter project with Docker by following the instructions in the README file but that didn't work.
To make it work, I had to change :
"GRAPHQL_URI=http://api:4000" in api/.env file to "GRAPHQL_URI=http://api:4000"
"REACT_APP_GRAPHQL_URI=http://localhost:4000" in ui/.env file to "REACT_APP_GRAPHQL_URI=http://localhost:4000/graphql"
I think it was because the UI could not send GET or POST requests to the server.
I might have added CORS with Express to make it work. But maybe it works without it too.
Hey,
I had to make some adjustments for making the backend api
as a micro-service.
You can check the new template repo: https://github.com/denvash/GRANDstack-backend-starter
Features
- Backend as micro-service.
- Empowered version of
grand-stack-stater

I believe this has to do with running the create-react-app
development server without an interactive shell. For instance, setting:
stdin_open: true
tty: true
in the docker-compose.yml
file works. Based on the discussion here: facebook/create-react-app#8688 it appears that the preferred solution is to set the environment variable CI=true
to tell react-scripts to not expect an interactive session.
The latest version of material-ui is 4.2.1, and some components break if the latest version of mui isn't used.
Codesandbox can host both node.js and React apps, but I'm not sure how it handles monorepos. Perhaps deploys as two separate codesandboxes?
the default schema will not be compatible with existing databases
(should probably check that, or that the db is empty)
an npm run inferSchema
that updates the schema file would be good
Hi, I would like to practice GraphQL and schema forming with this starter project. Is it possible for you to provide a copy of the Neo4j database used in the example?
I might have had it installed globally?
Perhaps a note makes sense.
I am new to neo4j (maybe I missing something).
Related forum issue (Without solution):
https://community.neo4j.com/t/grandstack-npm-run-seeddb-econnrefused/17680
I follow all the steps from readme.md
(Local setup
option).
Maybe related (my env file):
NEO4J_URI=bolt://localhost:7687
NEO4J_USER=neo4j
NEO4J_PASSWORD=letmein
GRAPHQL_LISTEN_PORT=4001
GRAPHQL_URI=http://localhost:4001/graphql
In the case where a non-default database is used, add option for specifying via .ENV file
Currently following the walkthrough at: https://www.youtube.com/watch?v=rPC71lUhK_I

Just tried the docker-compose route for spinning up the master branch, which fails out of the box just now because .env is pointing to localhost:4001 instead of localhost:4000. Was committed in April, am assuming it relates to work in progress or something?
Changing back to localhost:4000 gives you a working app.
I downloaded and started using the GRANDstack docker-compose.yml file -- thank you for such a quick start!
I ran into a problem in the UI: the initial "usersPaginateQuery" query is written incorrectly. As it is written, it encounters this HTTP 400 error at the API:
Query:
query usersPaginateQuery(
$first: Int
$offset: Int
$orderBy: _UserOrdering
) {
User(first: $first, offset: $offset, orderBy: $orderBy) {
id
name
avgStars
numReviews
}
}
Response:
Variable \"$orderBy\" of type \"_UserOrdering\" used in position expecting type \"[_UserOrdering]\"
By adding [
and ]
around "_UserOrdering" in the query, it then begins working. The correct query is:
query usersPaginateQuery(
$first: Int
$offset: Int
$orderBy: [_UserOrdering]
) {
User(first: $first, offset: $offset, orderBy: $orderBy) {
id
name
avgStars
numReviews
}
}
It's more confusing to do it at every start of the app.
Perhaps as a seedDb:indexes
I am trying to set up Authentication in my GrandStack starter. I have scoured the docs and graphql-auth-directives readme but I still can not set up authentication correctly. Is there a FULL working example using authentication in grandstack anywhere?? This would be SOOOO helpful. In the docs there are several different solutions mentioned but I have no idea how to set any of them up correctly. Any example of a fully working using authentication (signup/login) would go a long way.
Hello , i'm trying to add dateTime scalar, i followed this tuto https://www.okgrow.com/posts/using-scalar-types-to-improve-graphql-schemas , i populated my seeder with data, added a dateTime field to my type and inserted some data with created_at as dateTime but when i execute npm start i get the following error " throw new Error('Type "' + typeRef.name.value + '" not found in document.');
^
Error: Type "DateTime" not found in document."
I can't figure out what causes this error.

Hi, thanks for a great project. I was wondering how to provide a list of ids to a resolver.
{
User(["0", "22"]) {_id}
}
I'm following the documentation on custom scalars from packages and trying to add the JSON
scalar to the grand-stack-starter. I am getting an error whenever I try to start the api:
Error: Type "JSON" not found in document.
at ASTDefinitionBuilder._resolveType (/app/node_modules/graphql/utilities/buildASTSchema.js:134:11)
The only changes I made to the starter are those outlined in the docs: added a scalar JSON
to the schema and a new resolver:
schema.graphql
scalar JSON
type Foo {
aField: JSON
}
type User {
id: ID!
name: String
friends: [User] @relation(name: "FRIENDS", direction: "BOTH")
reviews: [Review] @relation(name: "WROTE", direction: "OUT")
avgStars: Float @cypher(statement: "MATCH (this)-[:WROTE]->(r:Review) RETURN toFloat(avg(r.stars))")
numReviews: Int @cypher(statement: "MATCH (this)-[:WROTE]->(r:Review) RETURN COUNT(r)")
}
type Business {
id: ID!
name: String
address: String
city: String
state: String
reviews: [Review] @relation(name: "REVIEWS", direction: "IN")
categories: [Category] @relation(name: "IN_CATEGORY", direction: "OUT")
}
type Review {
id: ID!
stars: Int
text: String
business: Business @relation(name: "REVIEWS", direction: "OUT")
user: User @relation(name: "WROTE", direction: "IN")
}
type Category {
name: ID!
businesses: [Business] @relation(name: "IN_CATEGORY", direction: "IN")
}
type Query {
usersBySubstring(substring: String, first: Int = 10, offset: Int = 0): [User] @cypher(statement: "MATCH (u:User) WHERE u.name CONTAINS $substring RETURN u")
}
graphql-schema.js
import { neo4jgraphql } from "neo4j-graphql-js";
import GraphQLJSON from 'graphql-type-json';
import fs from "fs";
import path from "path";
export const typeDefs = fs
.readFileSync(

)
.toString("utf-8");
export const resolvers = {
JSON: GraphQLJSON,
Query: {

}
};
What am I doing wrong here?

Hi,
as the title states. Couldn´t npm start the /ui without manually installing npm i classnames.
Consider adding this package to the package.json.
I'm used to working on python/graphene, so my question is likely simply a matter of my not being familiar with graphql-js and how neo4j-graphql fits in.
Hi
I am running a latest neo4j 4.x.x database in docker container. I can connect from neo4j browser without any issues(create, delete, fetch etc... all works) with bolt driver but not able connect to from the node js grandstack api project.
NOTE: It was working fine with the older version and I have upgraded the database and downloaded the latest API code from this repo.
ERROR #1: Please ensure that your database is listening on the correct host and port and that you have compatible encryption settings both on Neo4j server and driver. Note that the default encryption setting has changed in Neo4j 4.0. Caused by: connect EADDRNOTAVAIL 255.255.255.255:7687
Another issue: After default installation of the GRAND stack(out of the box) on windows OS, npm start is giving me an error as below. I had to split the commands( in windows bash (build separately then copy..) and run to make it to work (work around)

Currently the inferSchema.js script (which is used by npm run inferschema:write
) ignores the NEO4J_ENCRYPTED environment variable and just defaults to unencrypted:
https://github.com/grand-stack/grand-stack-starter/blob/master/scripts/inferSchema.js#L9
Take into account the encryption flag and the NEO4J_DATABASE env var when running this script
As a workaround --encrypted
can be manually appended to the call to the grandstack cli if encrypted connection is needed, for example:
node_modules/.bin/grandstack graphql inferschema --neo4j-uri neo4j://07de346a.databases.neo4j.io --neo4j-user summit --neo4j-password summit --schema-file ./api/src/schema.graphql --encrypted
The ability to use a modular or plugin based graphql schema would help greatly with using GraphQL in extensible applications using the GRAND stack.
