Create a js file that exports schema
, (and optionally keyReducers
and count
)
const keyReducers = {
"{env}": fakerjs => {
return fakerjs.random.arrayElement(["prod", "staging"]);
},
"{userID}": fakerjs => {
return fakerjs.random.alphaNumeric(5);
},
"{postID}": fakerjs => {
return fakerjs.random.alphaNumeric(5);
}
};
const schema = {
"{env}": {
users: {
"{userID}": {
comment_count: "number",
username: "string",
is_verified: "boolean",
created_at: "timestamp"
}
},
posts: {
"{postID}": {
post_title: "string",
post_data: (faker, key) => {
// return faker.random.words(5)
return key.split("/").join("-") + ":post_data";
},
author_id: "{userID}",
created_at: "timestamp"
}
},
comments: {
"{postID}": {
"{commentID}": {
value: "๐",
userID: "{userID}"
}
}
}
}
};
const count = 5;
module.exports = {
schema,
keyReducers,
count
};
Then run :
generate-json path/to/schema.js path/to/output-directory/
This will create 3 files in path/to/output-directory/
:
tree.json
keys.json
values.json
