It is packaged as a Neo4j user-defined procedure under the name `experimental.introspect.asJson({})`. 17 | -- 18 | 19 | == Compiling 20 | 21 | You need Java 17 for this project to compile and package. It is build against Neo4j 5 and thus requires Neo4j 5 to run. 22 | 23 | Assuming Neo4j is installed in a `NEO4J_HOME`, please execute the following steps 24 | 25 | .Stop your Neo4j instance (optional) 26 | [source,bash] 27 | ---- 28 | $NEO4J_HOME/bin/neo4j stop 29 | ---- 30 | 31 | .Package this project 32 | [source,bash] 33 | ---- 34 | ./mvnw -Dfast clean package 35 | ---- 36 | 37 | .Copy the resulting artifact into your Neo4j installation and start the latter 38 | [source,bash] 39 | ---- 40 | cp -v target/graph-schema-introspector-*.jar $NEO4J_HOME/plugins 41 | $NEO4J_HOME/bin/neo4j start 42 | ---- 43 | 44 | After a bit, the instance will have started. For the sake of a functional readme, we assume a database password `verysecret`. 45 | 46 | == Running 47 | 48 | === Retrieve the schema as JSON document 49 | 50 | You call the procedure like this: 51 | 52 | [source,cypher] 53 | ---- 54 | CALL experimental.introspect.asJson({prettyPrint: true}) 55 | ---- 56 | 57 | This will return a single column named `value` containing the schema of the database as valid JSON for further processing. 58 | 59 | The following command will use Cypher-Shell to pipe the JSON (with some post-processing) through `jq` and eventually to standard out: 60 | 61 | [source,bash] 62 | ---- 63 | $NEO4J_HOME/bin/cypher-shell -uneo4j -pverysecret --format plain --non-interactive 'CALL experimental.introspect.asJson({}) YIELD value RETURN value AS _json_' | sed -e 's/\\"/"/g' -e 's/^"//g' -e 's/"\$//g' -e 's/_json_//g' -e 's/"{/{/' -e 's/}"/}/' | jq 64 | ---- 65 | 66 | NOTE: In the script above, https://stedolan.github.io/jq/[`jq`] is used to format the JSON. While the UDF can pretty print, Cypher-Shell always quotes quotes (turning `"` into `\"`), thus making the output useless. Therefor it is processed first with `sed` and then piped through `jq`. 67 | 68 | === Retrieve the schema in a graphy format 69 | 70 | A visualization of that schema can be generated with the following statement: 71 | 72 | [source,cypher] 73 | ---- 74 | CALL experimental.introspect.asGraph({}) 75 | ---- 76 | 77 | It will visualize the schema document, not the graph itself. The result for the Movie example graph will look like this (you may have to configure the corresponding properties to be used as display names): 78 | 79 | image::docs/schema-graph.png[] 80 | 81 | A graphy result that reassembles the current `db.schema.visualization` can be achieved with 82 | 83 | [source,cypher] 84 | ---- 85 | CALL experimental.introspect.asGraph({flat:true}) 86 | ---- 87 | 88 | The same schema as above will look like this: 89 | 90 | image::docs/schema-graph-flat.png[] 91 | 92 | In both cases you'll find a `properties` field on the properties of node- and relationship object types containing the property information in the same format as the JSON field. In the latter visualization nodes that have multiple labels will only spot the first one as a `name` property and the full list will be available as standard labels or in the `$id` field in case you did use constant ids. 93 | 94 | == Options 95 | 96 | The following options can be passed as arguments: 97 | 98 | |=== 99 | |Name |Type |Meaning |Default 100 | 101 | |`prettyPrint` 102 | |Boolean 103 | |Pretty prints the generated JSON 104 | |`false` 105 | 106 | |`useConstantIds` 107 | |Boolean 108 | |Uses constant ids for the tokens, derived from their names.
